3e7aeb78ab Networking changes for 6.8. 
Core & protocols
 ----------------
 
  - Analyze and reorganize core networking structs (socks, netdev,
    netns, mibs) to optimize cacheline consumption and set up
    build time warnings to safeguard against future header changes.
    This improves TCP performances with many concurrent connections
    up to 40%.
 
  - Add page-pool netlink-based introspection, exposing the
    memory usage and recycling stats. This helps indentify
    bad PP users and possible leaks.
 
  - Refine TCP/DCCP source port selection to no longer favor even
    source port at connect() time when IP_LOCAL_PORT_RANGE is set.
    This lowers the time taken by connect() for hosts having
    many active connections to the same destination.
 
  - Refactor the TCP bind conflict code, shrinking related socket
    structs.
 
  - Refactor TCP SYN-Cookie handling, as a preparation step to
    allow arbitrary SYN-Cookie processing via eBPF.
 
  - Tune optmem_max for 0-copy usage, increasing the default value
    to 128KB and namespecifying it.
 
  - Allow coalescing for cloned skbs coming from page pools, improving
    RX performances with some common configurations.
 
  - Reduce extension header parsing overhead at GRO time.
 
  - Add bridge MDB bulk deletion support, allowing user-space to
    request the deletion of matching entries.
 
  - Reorder nftables struct members, to keep data accessed by the
    datapath first.
 
  - Introduce TC block ports tracking and use. This allows supporting
    multicast-like behavior at the TC layer.
 
  - Remove UAPI support for retired TC qdiscs (dsmark, CBQ and ATM) and
    classifiers (RSVP and tcindex).
 
  - More data-race annotations.
 
  - Extend the diag interface to dump TCP bound-only sockets.
 
  - Conditional notification of events for TC qdisc class and actions.
 
  - Support for WPAN dynamic associations with nearby devices, to form
    a sub-network using a specific PAN ID.
 
  - Implement SMCv2.1 virtual ISM device support.
 
  - Add support for Batman-avd mulicast packet type.
 
 BPF
 ---
 
  - Tons of verifier improvements:
    - BPF register bounds logic and range support along with a large
      test suite
    - log improvements
    - complete precision tracking support for register spills
    - track aligned STACK_ZERO cases as imprecise spilled registers. It
      improves the verifier "instructions processed" metric from single
      digit to 50-60% for some programs
    - support for user's global BPF subprogram arguments with few
      commonly requested annotations for a better developer experience
    - support tracking of BPF_JNE which helps cases when the compiler
      transforms (unsigned) "a > 0" into "if a == 0 goto xxx" and the
      like
    - several fixes
 
  - Add initial TX metadata implementation for AF_XDP with support in
    mlx5 and stmmac drivers. Two types of offloads are supported right
    now, that is, TX timestamp and TX checksum offload.
 
  - Fix kCFI bugs in BPF all forms of indirect calls from BPF into
    kernel and from kernel into BPF work with CFI enabled. This allows
    BPF to work with CONFIG_FINEIBT=y.
 
  - Change BPF verifier logic to validate global subprograms lazily
    instead of unconditionally before the main program, so they can be
    guarded using BPF CO-RE techniques.
 
  - Support uid/gid options when mounting bpffs.
 
  - Add a new kfunc which acquires the associated cgroup of a task
    within a specific cgroup v1 hierarchy where the latter is identified
    by its id.
 
  - Extend verifier to allow bpf_refcount_acquire() of a map value field
    obtained via direct load which is a use-case needed in sched_ext.
 
  - Add BPF link_info support for uprobe multi link along with bpftool
    integration for the latter.
 
  - Support for VLAN tag in XDP hints.
 
  - Remove deprecated bpfilter kernel leftovers given the project
    is developed in user-space (https://github.com/facebook/bpfilter).
 
 Misc
 ----
 
  - Support for parellel TC self-tests execution.
 
  - Increase MPTCP self-tests coverage.
 
  - Updated the bridge documentation, including several so-far
    undocumented features.
 
  - Convert all the net self-tests to run in unique netns, to
    avoid random failures due to conflict and allow concurrent
    runs.
 
  - Add TCP-AO self-tests.
 
  - Add kunit tests for both cfg80211 and mac80211.
 
  - Autogenerate Netlink families documentation from YAML spec.
 
  - Add yml-gen support for fixed headers and recursive nests, the
    tool can now generate user-space code for all genetlink families
    for which we have specs.
 
  - A bunch of additional module descriptions fixes.
 
  - Catch incorrect freeing of pages belonging to a page pool.
 
 Driver API
 ----------
 
  - Rust abstractions for network PHY drivers; do not cover yet the
    full C API, but already allow implementing functional PHY drivers
    in rust.
 
  - Introduce queue and NAPI support in the netdev Netlink interface,
    allowing complete access to the device <> NAPIs <> queues
    relationship.
 
  - Introduce notifications filtering for devlink to allow control
    application scale to thousands of instances.
 
  - Improve PHY validation, requesting rate matching information for
    each ethtool link mode supported by both the PHY and host.
 
  - Add support for ethtool symmetric-xor RSS hash.
 
  - ACPI based Wifi band RFI (WBRF) mitigation feature for the AMD
    platform.
 
  - Expose pin fractional frequency offset value over new DPLL generic
    netlink attribute.
 
  - Convert older drivers to platform remove callback returning void.
 
  - Add support for PHY package MMD read/write.

de927f6c0b s390 updates for 6.8 merge window 
- Add machine variable capacity information to /proc/sysinfo.
 
 - Limit the waste of page tables and always align vmalloc area size
   and base address on segment boundary.
 
 - Fix a memory leak when an attempt to register interruption sub class
   (ISC) for the adjunct-processor (AP) guest failed.
 
 - Reset response code AP_RESPONSE_INVALID_GISA to understandable
   by guest AP_RESPONSE_INVALID_ADDRESS in response to a failed
   interruption sub class (ISC) registration attempt.
 
 - Improve reaction to adjunct-processor (AP) AP_RESPONSE_OTHERWISE_CHANGED
   response code when enabling interrupts on behalf of a guest.
 
 - Fix incorrect sysfs 'status' attribute of adjunct-processor (AP) queue
   device bound to the vfio_ap device driver when the mediated device is
   attached to a guest, but the queue device is not passed through.
 
 - Rework struct ap_card to hold the whole adjunct-processor (AP) card
   hardware information. As result, all the ugly bit checks are replaced
   by simple evaluations of the required bit fields.
 
 - Improve handling of some weird scenarios between service element (SE)
   host and SE guest with adjunct-processor (AP) pass-through support.
 
 - Change local_ctl_set_bit() and local_ctl_clear_bit() so they return the
   previous value of the to be changed control register. This is useful if
   a bit is only changed temporarily and the previous content needs to be
   restored.
 
 - The kernel starts with machine checks disabled and is expected to enable
   it once trap_init() is called. However the implementation allows machine
   checks early. Consistently enable it in trap_init() only.
 
 - local_mcck_disable() and local_mcck_enable() assume that machine checks
   are always enabled. Instead implement and use local_mcck_save() and
   local_mcck_restore() to disable machine checks and restore the previous
   state.
 
 - Modification of floating point control (FPC) register of a traced
   process using ptrace interface may lead to corruption of the FPC

Pull s390 updates from Alexander Gordeev:

 - Add machine variable capacity information to /proc/sysinfo.

 - Limit the waste of page tables and always align vmalloc area size and
   base address on segment boundary.

 - Fix a memory leak when an attempt to register interruption sub class
   (ISC) for the adjunct-processor (AP) guest failed.

 - Reset response code AP_RESPONSE_INVALID_GISA to understandable by
   guest AP_RESPONSE_INVALID_ADDRESS in response to a failed
   interruption sub class (ISC) registration attempt.

 - Improve reaction to adjunct-processor (AP)
   AP_RESPONSE_OTHERWISE_CHANGED response code when enabling interrupts
   on behalf of a guest.

 - Fix incorrect sysfs 'status' attribute of adjunct-processor (AP)
   queue device bound to the vfio_ap device driver when the mediated
   device is attached to a guest, but the queue device is not passed
   through.

 - Rework struct ap_card to hold the whole adjunct-processor (AP) card
   hardware information. As result, all the ugly bit checks are replaced
   by simple evaluations of the required bit fields.

 - Improve handling of some weird scenarios between service element (SE)
   host and SE guest with adjunct-processor (AP) pass-through support.

 - Change local_ctl_set_bit() and local_ctl_clear_bit() so they return
   the previous value of the to be changed control register. This is
   useful if a bit is only changed temporarily and the previous content
   needs to be restored.

 - The kernel starts with machine checks disabled and is expected to
   enable it once trap_init() is called. However the implementation
   allows machine checks early. Consistently enable it in trap_init()
   only.

 - local_mcck_disable() and local_mcck_enable() assume that machine
   checks are always enabled. Instead implement and use
   local_mcck_save() and local_mcck_restore() to disable machine checks
   and restore the previous state.

 - Modification of floating point control (FPC) register of a traced
   process using ptrace interface may lead to corruption of the FPC
   register of the tracing process. Fix this.

 - kvm_arch_vcpu_ioctl_set_fpu() allows to set the floating point
   control (FPC) register in vCPU, but may lead to corruption of the FPC
   register of the host process. Fix this.

 - Use READ_ONCE() to read a vCPU floating point register value from the

c299010061 asm-generic cleanups for 6.8 
A series from Baoquan He cleans up the asm-generic/io.h to remove the
 ioremap_uc() definition from everything except x86, which still needs it
 for pre-PAT systems. This series notably contains a patch from Jiaxun Yang
 that converts MIPS to use asm-generic/io.h like every other architecture
 does, enabling future cleanups.
 
 Some of my own patches fix -Wmissing-prototype warnings in architecture
 specific code across several architectures. This is now needed as the
 warning is enabled by default. There are still some remaining warnings
 in minor platforms, but the series should catch most of the widely used
 ones make them more consistent with one another.
 
 David McKay fixes a bug in __generic_cmpxchg_local() when this is used
 on 64-bit architectures. This could currently only affect parisc64
 and sparc64.
 
 Additional cleanups address from Linus Walleij, Uwe Kleine-König,
 Thomas Huth, and Kefeng Wang help reduce unnecessary inconsistencies
 between architectures.

a05aea98d4 sysctl-6.8-rc1 
To help make the move of sysctls out of kernel/sysctl.c not incur a size
 penalty sysctl has been changed to allow us to not require the sentinel, the
 final empty element on the sysctl array. Joel Granados has been doing all this
 work. On the v6.6 kernel we got the major infrastructure changes required to
 support this. For v6.7 we had all arch/ and drivers/ modified to remove
 the sentinel. For v6.8-rc1 we get a few more updates for fs/ directory only.
 The kernel/ directory is left but we'll save that for v6.9-rc1 as those patches
 are still being reviewed. After that we then can expect also the removal of the
 no longer needed check for procname == NULL.
 
 Let us recap the purpose of this work:
 
   - this helps reduce the overall build time size of the kernel and run time
     memory consumed by the kernel by about ~64 bytes per array
   - the extra 64-byte penalty is no longer inncurred now when we move sysctls
     out from kernel/sysctl.c to their own files
 
 Thomas Weißschuh also sent a few cleanups, for v6.9-rc1 we expect to see further
 work by Thomas Weißschuh with the constificatin of the struct ctl_table.
 
 Due to Joel Granados's work, and to help bring in new blood, I have suggested
 for him to become a maintainer and he's accepted. So for v6.9-rc1 I look forward
 to seeing him sent you a pull request for further sysctl changes. This also
 removes Iurii Zaikin as a maintainer as he has moved on to other projects and
 has had no time to help at all.

78273df7f6 header cleanups for 6.8 
The goal is to get sched.h down to a type only header, so the main thing
 happening in this patchset is splitting out various _types.h headers and
 dependency fixups, as well as moving some things out of sched.h to
 better locations.
 
 This is prep work for the memory allocation profiling patchset which
 adds new sched.h interdepencencies.
 
 Testing - it's been in -next, and fixes from pretty much all
 architectures have percolated in - nothing major.

999a36b52b bcachefs updates for 6.8: 
- btree write buffer rewrite: instead of adding keys to the btree write
    buffer at transaction commit time, we know journal them with a
    different journal entry type and copy them from the journal to the
    write buffer just prior to journal write.
 
    This reduces the number of atomic operations on shared cachelines
    in the transaction commit path and is a signicant performance
    improvement on some workloads: multithreaded 4k random writes went
    from ~650k iops to ~850k iops.
 
  - Bring back optimistic spinning for six locks: the new implementation
    doesn't use osq locks; instead we add to the lock waitlist as normal,
    and then spin on the lock_acquired bit in the waitlist entry, _not_
    the lock itself.
 
  - BCH_IOCTL_DEV_USAGE_V2, which allows for new data types
  - BCH_IOCTL_OFFLINE_FSCK, which runs the kernel implementation of fsck
    but without mounting: useful for transparently using the kernel
    version of fsck from 'bcachefs fsck' when the kernel version is a
    better match for the on disk filesystem.
 
  - BCH_IOCTL_ONLINE_FSCK: online fsck. Not all passes are supported yet,
    but the passes that are supported are fully featured - errors may be
    corrected as normal.
 
    The new ioctls use the new 'thread_with_file' abstraction for kicking
    off a kthread that's tied to a file descriptor returned to userspace
    via the ioctl.
 
  - btree_paths within a btree_trans are now dynamically growable,
    instead of being limited to 64. This is important for the
    check_directory_structure phase of fsck, and also fixes some issues
    we were having with btree path overflow in the reflink btree.
 
  - Trigger refactoring; prep work for the upcoming disk space accounting
    rewrite
 
  - Numerous bugfixes :)

Merge tag 'bcachefs-2024-01-10' of https://evilpiepirate.org/git/bcachefs

Pull bcachefs updates from Kent Overstreet:

 - btree write buffer rewrite: instead of adding keys to the btree write
   buffer at transaction commit time, we now journal them with a
   different journal entry type and copy them from the journal to the
   write buffer just prior to journal write.

   This reduces the number of atomic operations on shared cachelines in
   the transaction commit path and is a signicant performance
   improvement on some workloads: multithreaded 4k random writes went
   from ~650k iops to ~850k iops.

 - Bring back optimistic spinning for six locks: the new implementation
   doesn't use osq locks; instead we add to the lock waitlist as normal,
   and then spin on the lock_acquired bit in the waitlist entry, _not_
   the lock itself.

 - New ioctls:

    - BCH_IOCTL_DEV_USAGE_V2, which allows for new data types

    - BCH_IOCTL_OFFLINE_FSCK, which runs the kernel implementation of
      fsck but without mounting: useful for transparently using the
      kernel version of fsck from 'bcachefs fsck' when the kernel
      version is a better match for the on disk filesystem.

    - BCH_IOCTL_ONLINE_FSCK: online fsck. Not all passes are supported
      yet, but the passes that are supported are fully featured - errors
      may be corrected as normal.

   The new ioctls use the new 'thread_with_file' abstraction for kicking
   off a kthread that's tied to a file descriptor returned to userspace
   via the ioctl.

 - btree_paths within a btree_trans are now dynamically growable,
   instead of being limited to 64. This is important for the
   check_directory_structure phase of fsck, and also fixes some issues
   we were having with btree path overflow in the reflink btree.

 - Trigger refactoring; prep work for the upcoming disk space accounting
   rewrite

 - Numerous bugfixes :)

Other than the update to MAINTAINERS, this PR has only a fix to stop
 ecryptfs from inadvertently mounting case-insensitive filesystems that
 it cannot handle, which would otherwise caused post-mount failures.  It
 has been on linux-next for the past month and a half.
 
 As a side note, the optimization to the case-insensitive comparison code
 that you suggested, and the negative dentry support are still on the
 list, and were postponed to the next release.

acc657692a keys, dns: Fix size check of V1 server-list header 
Fix the size check added to dns_resolver_preparse() for the V1 server-list
header so that it doesn't give EINVAL if the size supplied is the same as
the size of the header struct (which should be valid).

This can be tested with:

        echo -n -e '\0\0\01\xff\0\0' | keyctl padd dns_resolver desc @p

which will give "add_key: Invalid argument" without this fix.

Just a couple fixes and no new features. I've been reviewing and testing
 TPM patches for encrypted and integrity protected commuinications [1] but
 they did not made yet to this release.
 
 This was also first release I tested with my still heavily in-development
 test suite for linux integrity [2]. I'm refining this at the moment
 to run keyutils test suite, which could be potentially also run by a Gitlab
 runner for keyutis repository.

68da4c44b9 ext4: fix inconsistent between segment fstrim and full fstrim 
Suppose we issue two FITRIM ioctls for ranges [0,15] and [16,31] with
mininum length of trimmed range set to 8 blocks. If we have say a range of
blocks 10-22 free, this range will not be trimmed because it straddles the
boundary of the two FITRIM ranges and neither part is big enough. This is a
bit surprising to some users that call FITRIM on smaller ranges of blocks
to limit impact on the system. Also XFS trims all free space extents that
overlap with the specified range so we are inconsistent among filesystems.
Let's change ext4_try_to_trim_range() to consider for trimming the whole
free space extent that straddles the end of specified range, not just the
part of it within the range.

1f6bc02f18 ext4: fallback to complex scan if aligned scan doesn't work 
Currently in case the goal length is a multiple of stripe size we use
ext4_mb_scan_aligned() to find the stripe size aligned physical blocks.
In case we are not able to find any, we again go back to calling
ext4_mb_choose_next_group() to search for a different suitable block
group. However, since the linear search always begins from the start,
most of the times we end up with the same BG and the cycle continues.

With large fliesystems, the CPU can be stuck in this loop for hours
which can slow down the whole system. Hence, until we figure out a
better way to continue the search (rather than starting from beginning)
in ext4_mb_choose_next_group(), lets just fallback to
ext4_mb_complex_scan_group() in case aligned scan fails, as it is much
more likely to find the needed blocks.

There's nothing page-specific happening in ext4_da_do_write_end();
it's merely used for its refcount & lock, both of which are folio

7c784d6248 ext4: allow for the last group to be marked as trimmed 
The ext4 filesystem tracks the trim status of blocks at the group
level.  When an entire group has been trimmed then it is marked as
such and subsequent trim invocations with the same minimum trim size
will not be attempted on that group unless it is marked as able to be
trimmed again such as when a block is freed.

Currently the last group can't be marked as trimmed due to incorrect
logic in ext4_last_grp_cluster(). ext4_last_grp_cluster() is supposed
to return the zero based index of the last cluster in a group. This is
then used by ext4_try_to_trim_range() to determine if the trim
operation spans the entire group and as such if the trim status of the
group should be recorded.

ext4_last_grp_cluster() takes a 0 based group index, thus the valid
values for grp are 0..(ext4_get_groups_count - 1). Any group index
less than (ext4_get_groups_count - 1) is not the last group and must
have EXT4_CLUSTERS_PER_GROUP(sb) clusters. For the last group we need
to calculate the number of clusters based on the number of blocks in
the group. Finally subtract 1 from the number of clusters as zero
based indexing is expected.  Rearrange the function slightly to make
it clear what we are calculating and returning.

Reproducer:
// Create file system where the last group has fewer blocks than
// blocks per group
$ mkfs.ext4 -b 4096 -g 8192 /dev/nvme0n1 8191
$ mount /dev/nvme0n1 /mnt

Before Patch:
$ fstrim -v /mnt
/mnt: 25.9 MiB (27156480 bytes) trimmed
// Group not marked as trimmed so second invocation still discards blocks
$ fstrim -v /mnt
/mnt: 25.9 MiB (27156480 bytes) trimmed

After Patch:
fstrim -v /mnt
/mnt: 25.9 MiB (27156480 bytes) trimmed
// Group marked as trimmed so second invocation DOESN'T discard any blocks
fstrim -v /mnt
/mnt: 0 B (0 bytes) trimmed

Pull afs updates from David Howells:
 "The majority of the patches are aimed at fixing and improving the AFS
  filesystem's rotation over server IP addresses, but there are also
  some fixes from Oleg Nesterov for the use of read_seqbegin_or_lock().

   - Fix fileserver probe handling so that the next round of probes
     doesn't break ongoing server/address rotation by clearing all the
     probe result tracking. This could occasionally cause the rotation
     algorithm to drop straight through, give a 'successful' result
     without actually emitting any RPC calls, leaving the reply buffer
     in an undefined state.

     Instead, detach the probe results into a separate struct and
     allocate a new one each time we start probing and update the
     pointer to it. Probes are also sent in order of address preference
     to try and improve the chance that the preferred one will complete
     first.

   - Fix server rotation so that it uses configurable address
     preferences across on the probes that have completed so far than
     ranking them by RTT as the latter doesn't necessarily give the best
     route. The preference list can be altered by writing into
     /proc/net/afs/addr_prefs.

   - Fix the handling of Read-Only (and Backup) volume callbacks as
     there is one per volume, not one per file, so if someone performs a
     command that, say, offlines the volume but doesn't change it, when
     it comes back online we don't spam the server with a status fetch
     for every vnode we're using. Instead, check the Creation timestamp
     in the VolSync record when prompted by a callback break.

   - Handle volume regression (ie. a RW volume being restored from a
     backup) by scrubbing all cache data for that volume. This is
     detected from the VolSync creation timestamp.

   - Adjust abort handling and abort -> error mapping to match better
     with what other AFS clients do.

   - Fix offline and busy volume state handling as they only apply to
     individual server instances and not entire volumes and the rotation
     algorithm should go and look at other servers if available. Also
     make it sleep briefly before each retry if all the volume instances
     are unavailable"

Pull btrfs updates from David Sterba:
 "There are no exciting changes for users, it's been mostly API
  conversions and some fixes or refactoring.

  The mount API conversion is a base for future improvements that would
  come with VFS. Metadata processing has been converted to folios, not
  yet enabling the large folios but it's one patch away once everything
  gets tested enough.

  Core changes:

   - convert extent buffers to folios:
      - direct API conversion where possible
      - performance can drop by a few percent on metadata heavy
        workloads, the folio sizes are not constant and the calculations
        add up in the item helpers
      - both regular and subpage modes
      - data cannot be converted yet, we need to port that to iomap and
        there are some other generic changes required

   - convert mount to the new API, should not be user visible:
      - options deprecated long time ago have been removed: inode_cache,
        recovery
      - the new logic that splits mount to two phases slightly changes
        timing of device scanning for multi-device filesystems
      - LSM options will now work (like for selinux)

   - convert delayed nodes radix tree to xarray, preserving the
     preload-like logic that still allows to allocate with GFP_NOFS

   - more validation of sysfs value of scrub_speed_max

   - refactor chunk map structure, reduce size and improve performance

   - extent map refactoring, smaller data structures, improved
     performance

   - reduce size of struct extent_io_tree, embedded in several
     structures

   - temporary pages used for compression are cached and attached to a
     shrinker, this may slightly improve performance

   - in zoned mode, remove redirty extent buffer tracking, zeros are
     written in case an out-of-order is detected and proper data are
     written to the actual write pointer

   - cleanups, refactoring, error message improvements, updated tests

   - verify and update branch name or tag

   - remove unwanted text"

496530c7c1 erofs: avoid debugging output for (de)compressed data 
Syzbot reported a KMSAN warning,

The root cause is that the printed decompressed buffer may be filled

used for debugging, get rid of them now.

41daf06ea1 linux_kselftest-kunit-6.8-rc1 
This KUnit update for Linux 6.8-rc1 consists of:
 
 - a new feature that adds APIs for managing devices introducing
   a set of helper functions which allow devices (internally a
   struct kunit_device) to be created and managed by KUnit.
   These devices will be automatically unregistered on
   test exit. These helpers can either use a user-provided
   struct device_driver, or have one automatically created and
   managed by KUnit. In both cases, the device lives on a new
   kunit_bus.
 
 - changes to switch drm/tests to use kunit devices
 
 - several fixes and enhancements to attribute feature
 
 - changes to reorganize deferred action function introducing
   KUNIT_DEFINE_ACTION_WRAPPER
 
 - new feature adds ability to run tests after boot using debugfs
 
 - fixes and enhancements to string-stream-test:
   - parse ERR_PTR in string_stream_destroy()
   - unchecked dereference in bug fix in debugfs_print_results()
   - handling errors from alloc_string_stream()

Pull power management updates from Rafael Wysocki:
 "These add support for new processors (Sierra Forest, Grand Ridge and
  Meteor Lake) to the intel_idle driver, make intel_pstate run on
  Emerald Rapids without HWP support and adjust it to utilize EPP values
  supplied by the platform firmware, fix issues, clean up code and
  improve documentation.

  The most significant fix addresses deadlocks in the core system-wide
  resume code that occur if async_schedule_dev() attempts to run its
  argument function synchronously (for example, due to a memory
  allocation failure). It rearranges the code in question which may
  increase the system resume time in some cases, but this basically is a
  removal of a premature optimization. That optimization will be added
  back later, but properly this time.

Pull thermal control updates from Rafael Wysocki:
 "These add support for the D1/T113s THS controller to the sun8i driver
  and a DT-based mechanism for platforms to indicate a preference to
  reboot (instead of shutting down) on crossing a critical trip point,
  fix issues, make other improvements (in the IPA governor, the Intel
  HFI driver, the exynos driver and the thermal netlink interface among
  other places) and clean up code.

  One long-standing issue addressed here is that trip point crossing
  notifications sent to user space might be unreliable due to the
  incorrect handling of trip point hysteresis in the thermal core:
  multiple notifications might be sent for the same event or there might
  be events without any notification at all.

Pull ACPI updates from Rafael Wysocki:
 "From the new features standpoint, the most significant change here is
  the addition of CSI-2 and MIPI DisCo for Imaging support to the ACPI
  device enumeration code that will allow MIPI cameras to be enumerated
  through the platform firmware on systems using ACPI.

  Also significant is the switch-over to threaded interrupt handlers for
  the ACPI SCI and the dedicated EC interrupt (on systems where the
  former is not used) which essentially allows all ACPI code to run with
  local interrupts enabled. That should improve responsiveness
  significantly on systems where multiple GPEs are enabled and the
  handling of one SCI involves many I/O address space accesses which
  previously had to be carried out in one go with disabled interrupts on
  the local CPU.

  Apart from the above, the ACPI thermal zone driver will use the
  Thermal fast Sampling Period (_TFP) object if available, which should
  allow temperature changes to be followed more accurately on some
  systems, the ACPI Notify () handlers can run on all CPUs (not just on
  CPU0), which should generally speed up the processing of events
  signaled through the ACPI SCI, and the ACPI power button driver will
  trigger wakeup key events via the input subsystem (on systems where it
  is a system wakeup device)

  In addition to that, there are the usual bunch of fixes and cleanups.

  Specifics:

   - Add CSI-2 and DisCo for Imaging support to the ACPI device
     enumeration code (Sakari Ailus, Rafael J. Wysocki)

   - Adjust the cpufreq thermal reduction algorithm in the ACPI
     processor driver for Tegra241 (Srikar Srimath Tirumala, Arnd
     Bergmann)

   - Make acpi_proc_quirk_mwait_check() x86-specific (Rafael J. Wysocki)

   - Switch over ACPI to using a threaded interrupt handler for the SCI
     (Rafael J. Wysocki)

   - Allow ACPI Notify () handlers to run on all CPUs and clean up the
     ACPI interface for deferred events processing (Rafael J. Wysocki)

   - Switch over the ACPI EC driver to using a threaded handler for the
     dedicated IRQ on systems without the EC GPE (Rafael J. Wysocki)

   - Adjust code using ACPICA spinlocks and the ACPI EC driver spinlock
     to keep local interrupts on (Rafael J. Wysocki)

     lists (Rafael J. Wysocki)

35f11a3710 * MTD 
Apart from preventing the mtdblk to run on top of ftl or ubiblk (which
 may cause security issues and has no meaning anyway), there are a few
 misc fixes.
 
 * Raw NAND
 
 Two meaningful changes this time. The conversion of the brcmnand driver
 to the ->exec_op() API, this series brought additional changes to the
 core in order to help controller drivers to handle themselves the WP pin
 during destructive operations when relevant.
 
 There is also a series bringing important fixes to the sequential read
 feature.
 
 As always, there is as well a whole bunch of miscellaneous W=1 fixes,
 together with a few runtime fixes (double free, timeout value, OOB
 layout, missing register initialization) and the usual load of remove
 callbacks turned into void (which led to switch the txx9ndfmc driver to
 use module_platform_driver()).
 
 * SPI NOR
 
 SPI NOR comes with die erase support for multi die flashes, with new
 octal protocols (1-1-8 and 1-8-8) parsed from SFDP and with an updated
 documentation about what the contributors shall consider when proposing
 flash additions or updates.

da96801729 regulator: Updates for v6.8 
The main updates for this release are around monitoring of regulators,
 largely for error handling purposes.  We allow the stream of regulator
 events to be seen by userspace as netlink events and allow system
 integrators to describe individual regulators as system critical with
 information on how long the system is expected to last on error.  The
 system level error handling is very much about best effort problem
 mitigation rather than providing something fully robust, the initial
 drive was to provide a mechanism for trying to avoid initiating any new
 writes to flash once we notice the power going out.
 
 Otherwise it's very quiet, mainly several new Qualcomm devices.
 
  - Support for marking regulators as system critical and providing
    information on how long the system might last with those regulators
    in a failure state, hooked into the existing critical shutdown error
    handling.
  - Optional support for generating netlink events for events, there are
    use cases for system monitoring UIs and error handling.
  - A command line option to leave unused controllable regulators
    enabled, useful for debugging.  We already only disable regulators we
    were explicitly given permission to control.
  - Support for Quacomm MP5496, PM8010 and PM8937.
