6e10aa1fee rpmsg updates for v6.12
This performs minor cleanup/refactor of the Qualcomm GLINK code, in
 order to then add trace events related to the messages exchange with the
 remote side, useful for debugging a range of interoperability issues.
 
 The nested structs with flexible array members, in the same driver, is
 then rewritten to avoid the risk of invalid accesses.

5c480f1da8 remoteproc updates for v6.12
This adds remoteproc support for the Cortex M4F found in AM62x and AM64x
 of the TI K3 family, support for the modem remoteproc in the Qualcomm
 SDX75, and audio, compute and general-purpose DSPs of the Qualcomm
 SA8775P.
 
 The i.MX remoteproc driver gains support for blocking and non-blocking
 mailbox transmissions, followed by the implementation of poweroff and
 reboot mechanisms, using the same. This is followed by a few bug fixes
 and minor improvements.
 
 A few cleanups and bug fixes for the TI K3 DSP and R5F drivers are
 introduced.
 
 Support for mapping SRAM regions into the AMD-Xilinx Zynqmp R5 cores is
 added.
 
 The Ingenic, TI DA8xx, TI Keystone, TI K3, ST slim drivers are
 simplified using devres helpers for various allocations.
 
 Uses of of_{find,get}_property() are replaced with of_property_present()
 where possible.

 "Mostly just a set of fixes in here, or little changes that didn't get
  included in the initial pull request. This contains:

   - Move the SQPOLL napi polling outside the submission lock (Olivier)

   - Rename of the "copy buffers" API that got added in the 6.12 merge
     window. There's really no copying going on, it's just referencing
     the buffers. After a bit of consideration, decided that it was
     better to simply rename this to avoid potential confusion (me)

   - Shrink struct io_mapped_ubuf from 48 to 32 bytes, by changing it to
     start + len tracking rather than having start / end in there, and
     by removing the caching of folio_mask when we can just calculate it
     from folio_shift when we need it (me)

   - Fixes for the SQPOLL affinity checking (me, Felix)

   - Fix for how cqring waiting checks for the presence of task_work.
     Just check it directly rather than check for a specific
     notification mechanism (me)

   - Tweak to how request linking is represented in tracing (me)

   - Fix a syzbot report that deliberately sets up a huge list of
     overflow entries, and then hits rcu stalls when flushing this list.
     Just check for the need to preempt, and drop/reacquire locks in the
     loop. There's no state maintained over the loop itself, and each
     entry is yanked from head-of-list (me)"

9ab27b0186 The core clk framework is left largely untouched this time around except for
support for the newly ratified DT property 'assigned-clock-rates-u64'. I'm much
 more excited about the support for loading DT overlays from KUnit tests so that
 we can test how the clk framework parses DT nodes during clk registration. The
 clk framework has some places that are highly DeviceTree dependent so this
 charts the path to extend the KUnit tests to cover even more framework code in
 the future. I've got some more tests on the list that use the DT overlay
 support, but they uncovered issues with clk unregistration that I'm still
 working on fixing.
 
 Outside the core, the clk driver update pile is dominated by Qualcomm and
 Renesas SoCs, making it fairly usual. Looking closer, there are fixes for
 things all over the place, like adding missing clk frequencies or moving
 defines for the number of clks out of DT binding headers into the drivers.
 There are even conversions of DT bindings to YAML and migration away from
 strings to describe clk topology. Overall it doesn't look unusual so I expect
 the new drivers to be where we'll have fixes in the coming weeks.
 
 Core:
  - KUnit tests for clk registration and fixed rate basic clk type
  - A couple more devm helpers, one consumer and one provider
  - Support for assigned-clock-rates-u64
 
 New Drivers:
  - Camera, display and GPU clocks on Qualcomm SM4450
  - Camera clocks on Qualcomm SM8150
  - Rockchip rk3576 clks
  - Microchip SAM9X7 clks
  - Renesas RZ/V2H(P) (R9A09G057) clks
 
 Updates:
  - Mark a bunch of struct freq_tbl const to reduce .data usage
  - Add Qualcomm MSM8226 A7PLL and Regera PLL support
  - Fix the Qualcomm Lucid 5LPE PLL configuration sequence to not reuse
    Trion, as they do differ
  - A number of fixes to the Qualcomm SM8550 display clock driver
  - Fold Qualcomm SM8650 display clock driver into SM8550 one
  - Add missing clocks and GDSCs needed for audio on Qualcomm MSM8998
  - Add missing USB MP resets, GPLL9, and QUPv3 DFS to Qualcomm SC8180X
  - Fix sdcc clk frequency tables on Qualcomm SC8180X
  - Drop the Qualcomm SM8150 gcc_cpuss_ahb_clk_src
  - Mark Qualcomm PCIe GDSCs as RET_ON on sm8250 and sm8540 to avoid them
    turning off during suspend
  - Use the HW_CTRL mechanism on Qualcomm SM8550 video clock controller
    GDSCs
  - Get rid of CLK_NR_CLKS defines in Rockchip DT binding headers
  - Some fixes for Rockchip rk3228 and rk3588
  - Exynos850: Add clock for Thermal Management Unit
  - Exynos7885: Fix duplicated ID in the header, add missing TOP PLLs and
    add clocks for USB block in the FSYS clock controller
  - ExynosAutov9: Add DPUM clock controller
  - ExynosAutov920: Add new (first) clock controllers: TOP and PERIC0

Merge tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux

Pull clk updates from Stephen Boyd:
 "The core clk framework is left largely untouched this time around
  except for support for the newly ratified DT property
  'assigned-clock-rates-u64'.

  I'm much more excited about the support for loading DT overlays from
  KUnit tests so that we can test how the clk framework parses DT nodes
  during clk registration. The clk framework has some places that are
  highly DeviceTree dependent so this charts the path to extend the
  KUnit tests to cover even more framework code in the future. I've got
  some more tests on the list that use the DT overlay support, but they
  uncovered issues with clk unregistration that I'm still working on
  fixing.

  Outside the core, the clk driver update pile is dominated by Qualcomm
  and Renesas SoCs, making it fairly usual. Looking closer, there are
  fixes for things all over the place, like adding missing clk
  frequencies or moving defines for the number of clks out of DT binding
  headers into the drivers. There are even conversions of DT bindings to
  YAML and migration away from strings to describe clk topology. Overall
  it doesn't look unusual so I expect the new drivers to be where we'll
  have fixes in the coming weeks.

  Core:
   - KUnit tests for clk registration and fixed rate basic clk type
   - A couple more devm helpers, one consumer and one provider
   - Support for assigned-clock-rates-u64

  New Drivers:
   - Camera, display and GPU clocks on Qualcomm SM4450
   - Camera clocks on Qualcomm SM8150
   - Rockchip rk3576 clks
   - Microchip SAM9X7 clks
   - Renesas RZ/V2H(P) (R9A09G057) clks

  Updates:
   - Mark a bunch of struct freq_tbl const to reduce .data usage
   - Add Qualcomm MSM8226 A7PLL and Regera PLL support
   - Fix the Qualcomm Lucid 5LPE PLL configuration sequence to not reuse
     Trion, as they do differ
   - A number of fixes to the Qualcomm SM8550 display clock driver
   - Fold Qualcomm SM8650 display clock driver into SM8550 one
   - Add missing clocks and GDSCs needed for audio on Qualcomm MSM8998
   - Add missing USB MP resets, GPLL9, and QUPv3 DFS to Qualcomm SC8180X
   - Fix sdcc clk frequency tables on Qualcomm SC8180X
   - Drop the Qualcomm SM8150 gcc_cpuss_ahb_clk_src
   - Mark Qualcomm PCIe GDSCs as RET_ON on sm8250 and sm8540 to avoid
     them turning off during suspend
   - Use the HW_CTRL mechanism on Qualcomm SM8550 video clock controller

4e2c9cd7dc i2c-for-6.12-rc1
I2C core
 ========
 
 After 15 years of deprecation, the I2C_COMPAT symbol has finally been
 removed. Also client addresses are now locked during initialization to
 prevent race conditions between different kinds of instantiation. Scoped
 foreach OF child loops are now used. And the testunit has received some
 cleanups and documentation improvements as well as two new tests, one
 for repeated start and one for triggering SMBusAlert interrupts.
 
 I2C host drivers
 ================
 
 The DesignWare and the Renesas I2C drivers have received most of
 the changes in this pull request.
 
 The first has has undergone through a series of cleanups that
 have been sent to the mailing list a year ago for the first time
 and finally get merged in this pull request. They are many, from
 typos (e.g. i2/i2c), to cosmetics, to refactoring (e.g. move
 inline functions to librarieas) and many others.
 
 Besides that, all the DesignWare Kconfig options have been
 grouped under the I2C_DESIGNWARE_CORE and this required some
 adaptation in many of the kernel configuration files for
 different arm and mips boards.
 
 Follows the list of the rest of the changes grouped by type of
 change.
 
 Cleanups
 --------
 The Qualcomm Geni platform improves the exit path in the runtime
 resume function.
 
 The Intel LJCA driver loses "target_addr" parameter in
 ljca_i2c_stop() because it was unused.
 
 The MediaTek controller intializes the restart_flag in the
 transfer function using the ternary conditional operator ("? :")
 instead of initializing it in different parts.
 
 Constified a few global data structures in the virtio driver.
 
 The Renesas driver simplifies the bus speed handling in the init
 function making it more readable.
 
 Improved an if/else statement in probe function of the Renesas
 R-Car driver.
 
 The iMX/MXC driver switches to using the RUNTIME_PM_OPS() instead
 of SET_RUNTIME_PM_OPS().
 
 Still in the iMX/MXC driver a comma ',' has been replaced by a
 semicolon ';', while in different drivers the ',' has been
 removed from the '{ }' delimiters.
 
 Finally three devm_clk_get_enabled() have been used to simplify
 the devm_clk_get/clk_prepare_enable tuple in the Renesas EMEV2,
 Ingenic and MPC drivers.
 
 Refactors
 ---------
 The Nuvoton fixes a potential out of boundary array access. This
 is not a bug fix because the issue could never occur due to
 hardware not having the properties listed in the array. The
 change makes the driver more future proof and, at the same time,
 silences code analyzers.
 
 Improvements
 ------------
 The Renesas I2C (riic) driver undergoes several patches improving
 the runtime power management handling.
 
 The Intel i801 driver uses a more descriptive adapter's name to
 show the presence of the IDF feature.
 
 In the Intel Denverton (ismt) adapter the pending transactions
 are killed when irq's can't complete their handling, triggering a
 timeout. This could have been considered as a bug fix, but
 because, standing to Vasily, it's very sporadic, I preferred
 considering the patch rather as an improvement.
 
 New Feature
 -----------
 The Renesas I2C (riic) driver now supports the fast mode plus.
 
 New support
 -----------
 Added support for:
 
     - Renesas R9A08G045
     - Rockchip RK3576
     - KEBA I2C
     - Theobroma Systems Mule Multiplexer.
 
 The Keba comes with a new driver, i2c-keba.c.
 The Mule is an i2c multiplexer and it also comes with a new
 driver, mux/i2c-mux-mule.c.
 
 Core patch
 ----------
 This pull request includes also a patch in the I2C framework, in
 i2c-core-base.c where the runtime PM functions have been replaced
 in order to allow to be accessed during the device add.
 
 Devicetree
 ----------
 Some cleanups in the devicetree, as well. nVidia and Qualcomm
 bindings improve their "if:then:" blocks. While the aspeed
 binding loses the "multi-master" property because it was
 redundant.
 
 The i2c-sprd binding has been converted to YAML.

d7dfb07d4d firewire updates for v6.12
The batch of changes includes the followwing:
 
 - Replacing tasklet with usual workqueue for isochronous context
 - Replacing IDR with XArray
 - Utilizing guard macro where possible
 - Printing deprecation warning when enabling debug parameter of
   firewire-ohci module
 
 Additionally, it includes a single patch for sound subsystem which the
 subsystem maintainer acked:
 
 - Switching to nonatomic PCM operation
 
 In FireWire subsystem, tasklet has been used as the bottom half of 1394
 OHCi hardIRQ so long. In the recent kernel updates, BH workqueue has
 been available, and some developers have proposed replacing tasklet with
 BH workqueue. While it is fortunate that developers are still considering
 the legacy subsystem, a simple replacement is not necessarily suitable.
 
 As a first step towards dropping tasklet, I've investigated the
 feasibility for 1394 OHCI isochronous context, and concluded that usual
 workqueue is available. In the context, the batch of packets is processed
 in the specific queue, thus the timing jitter caused by task scheduling is
 not so critical. Additionally, DMA transmission can be scheduled
 per-packet basis, therefore the context can be sleep between the operation
 of transmissions. Furthermore, in-kernel protocol implementation involves
 some CPU-bound tasks, which can sometimes consumes CPU time so long. These
 characteristics suggest that usual workqueue is suitable, through BH
 workqueues are not.
 
 The replacement with usual workqueue allows unit drivers to process the
 content of packets in non-atomic context. It brings some reliefs to some
 drivers in sound subsystem that spin-lock is not mandatory anymore during
 isochronous packet processing.

Pull pci updates from Bjorn Helgaas:
 "Enumeration:

   - Wait for device readiness after reset by polling Vendor ID and
     looking for Configuration RRS instead of polling the Command
     register and looking for non-error completions, to avoid hardware
     retries done for RRS on non-Vendor ID reads (Bjorn Helgaas)

   - Rename CRS Completion Status to RRS ('Request Retry Status') to
     match PCIe r6.0 spec usage (Bjorn Helgaas)

   - Clear LBMS bit after a manual link retrain so we don't try to
     retrain a link when there's no downstream device anymore (Maciej W.
     Rozycki)

   - Revert to the original link speed after retraining fails instead of
     leaving it restricted to 2.5GT/s, so a future device has a chance
     to use higher speeds (Maciej W. Rozycki)

   - Wait for each level of downstream bus, not just the first, to
     become accessible before restoring devices on that bus (Ilpo
     Järvinen)

     single IRQ line and cannot set the affinity of each MSI to a
     specific CPU core (Marek Vasut)

   - Use MSI_FLAG_NO_AFFINITY and remove unnecessary .irq_set_affinity()
     implementations in aardvark, altera, brcmstb, dwc, mediatek-gen3,
     mediatek, mobiveil, plda, rcar, tegra, vmd, xilinx-nwl,
     xilinx-xdma, and xilinx drivers to avoid 'IRQ: set affinity failed'

   - Add support for the ACPI _DSM PCIe SSD status LED management, which
     is functionally similar to NPEM but mediated by platform firmware
     (Mariusz Tkaczyk)

  Device trees:

   - Drop minItems and maxItems from ranges in PCI generic host binding
     since host bridges may have several MMIO and I/O port apertures
     (Frank Li)

   - Add kirin, rcar-gen2, uniphier DT binding top-level constraints for
     clocks (Krzysztof Kozlowski)

  Altera PCIe controller driver:

   - Convert altera DT bindings from text to YAML (Matthew Gerlach)

   - Replace TLP_REQ_ID() with macro PCI_DEVID(), which does the same
     thing and is what other drivers use (Jinjie Ruan)

  Broadcom STB PCIe controller driver:

     statements (Frank Li)

   - Expand comments for erratum ERR010728 workaround (Frank Li)

736cd2c1ae nfs: add "NFS Client and Server Interlock" section to localio.rst
This section answers a new FAQ entry:

9. How does LOCALIO make certain that object lifetimes are managed
   properly given NFSD and NFS operate in different contexts?

   See the detailed "NFS Client and Server Interlock" section below.

The first half of the section details NeilBrown's elegant design
for LOCALIO's nfs_uuid_t based interlock and is heavily based on
Neil's "net namespace refcounting" description here:
  https://marc.info/?l=linux-nfs&m=172498546024767&w=2

The second half of the section details the per-cpu-refcount introduced
to ensure NFSD's nfsd_serv isn't destroyed while in use by a LOCALIO
client.

92945bd81c nfs: add Documentation/filesystems/nfs/localio.rst
This document gives an overview of the LOCALIO auxiliary RPC protocol
added to the Linux NFS client and server to allow them to reliably
handshake to determine if they are on the same host.

Once an NFS client and server handshake as "local", the client will
bypass the network RPC protocol for read, write and commit operations.
Due to this XDR and RPC bypass, these operations will operate faster.

56bcd0f07f nfs: implement client support for NFS_LOCALIO_PROGRAM
The LOCALIO auxiliary RPC protocol consists of a single "UUID_IS_LOCAL"
RPC method that allows the Linux NFS client to verify the local Linux
NFS server can see the nonce (single-use UUID) the client generated and
made available in nfs_common for subsequent lookup and verification
by the NFS server.  If matched, the NFS server populates members in the
nfs_uuid_t struct.  The NFS client then transfers these nfs_uuid_t
struct member pointers to the nfs_client struct and cleans up the
nfs_uuid_t struct.  See: fs/nfs/localio.c:nfs_local_probe()

This protocol isn't part of an IETF standard, nor does it need to be
considering it is Linux-to-Linux auxiliary RPC protocol that amounts
to an implementation detail.

Localio is only supported when UNIX-style authentication (AUTH_UNIX, aka
AUTH_SYS) is used (enforced by fs/nfs/localio.c:nfs_local_probe()).

The UUID_IS_LOCAL method encodes the client generated uuid_t in terms of
the fixed UUID_SIZE (16 bytes).  The fixed size opaque encode and decode
XDR methods are used instead of the less efficient variable sized
methods.

Having a nonce (single-use uuid) is better than using the same uuid
for the life of the server, and sending it proactively by client
rather than reactively by the server is also safer.

b9f5dd57f4 nfs/localio: use dedicated workqueues for filesystem read and write
For localio access, don't call filesystem read() and write() routines
directly.  This solves two problems:

1) localio writes need to use a normal (non-memreclaim) unbound
   workqueue.  This avoids imposing new requirements on how underlying
   filesystems process frontend IO, which would cause a large amount
   of work to update all filesystems.  Without this change, when XFS
   starts getting low on space, XFS flushes work on a non-memreclaim
   work queue, which causes a priority inversion problem:

2) Some filesystem writeback routines can end up taking up a lot of
   stack space (particularly XFS).  Instead of risking running over
   due to the extra overhead from the NFS stack, we should just call
   these routines from a workqueue job.  Since we need to do this to
   address 1) above we're able to avoid possibly blowing the stack
   "for free".

Use of dedicated workqueues improves performance over using the
system_unbound_wq.

Also, the creds used to open the file are used to override_creds() in
both nfs_local_call_read() and nfs_local_call_write() -- otherwise the
workqueue could have elevated capabilities (which the caller may not).

Lastly, care is taken to set PF_LOCAL_THROTTLE | PF_MEMALLOC_NOIO in
nfs_do_local_write() to avoid writeback deadlocks.

The PF_LOCAL_THROTTLE flag prevents deadlocks in balance_dirty_pages()
by causing writes to only be throttled against other writes to the
same bdi (it keeps the throttling local).  Normally all writes to
bdi(s) are throttled equally (after throughput factors are allowed
for).

The PF_MEMALLOC_NOIO flag prevents the lower filesystem IO from
causing memory reclaim to re-enter filesystems or IO devices and so
prevents deadlocks from occuring where IO that cleans pages is
waiting on IO to complete.

70ba381e1a nfs: add LOCALIO support
Add client support for bypassing NFS for localhost reads, writes, and
commits. This is only useful when the client and the server are
running on the same host.

nfs_local_probe() is stubbed out, later commits will enable client and
server handshake via a Linux-only LOCALIO auxiliary RPC protocol.

This has dynamic binding with the nfsd module (via nfs_localio module
which is part of nfs_common). LOCALIO will only work if nfsd is
already loaded.

The "localio_enabled" nfs kernel module parameter can be used to
disable and enable the ability to use LOCALIO support.

CONFIG_NFS_LOCALIO enables NFS client support for LOCALIO.

Lastly, LOCALIO uses an nfsd_file to initiate all IO. To make proper
use of nfsd_file (and nfsd's filecache) its lifetime (duration before
nfsd_file_put is called) must extend until after commit, read and
write operations. So rather than immediately drop the nfsd_file
reference in nfs_local_open_fh(), that doesn't happen until
nfs_local_pgio_release() for read/write and not until
nfs_local_release_commit_data() for commit. The same applies to the
reference held on nfsd's nn->nfsd_serv. Both objects' lifetimes and
associated references are managed through calls to
nfs_to->nfsd_file_put_local().

fa4983862e nfsd: add LOCALIO support
Add server support for bypassing NFS for localhost reads, writes, and
commits. This is only useful when both the client and server are
running on the same host.

If nfsd_open_local_fh() fails then the NFS client will both retry and
fallback to normal network-based read, write and commit operations if
localio is no longer supported.

Care is taken to ensure the same NFS security mechanisms are used
(authentication, etc) regardless of whether localio or regular NFS
access is used.  The auth_domain established as part of the traditional
NFS client access to the NFS server is also used for localio.  Store
auth_domain for localio in nfsd_uuid_t and transfer it to the client
if it is local to the server.

Relative to containers, localio gives the client access to the network
namespace the server has.  This is required to allow the client to
access the server's per-namespace nfsd_net struct.

This commit also introduces the use of NFSD's percpu_ref to interlock
nfsd_destroy_serv and nfsd_open_local_fh, to ensure nn->nfsd_serv is
not destroyed while in use by nfsd_open_local_fh and other LOCALIO
client code.

symbols to the NFS client:

- Make nfsd_open_local_fh() symbol and other required NFSD symbols
  available to NFS in a global 'nfs_to' nfsd_localio_operations
  struct (global access suggested by Trond, nfsd_localio_operations
  suggested by NeilBrown).  The next commit will also introduce
  nfsd_localio_ops_init() that init_nfsd() will call to initialize
  'nfs_to'.

- Introduce nfsd_file_file() that provides access to nfsd_file's
  backing file.  Keeps nfsd_file structure opaque to NFS client (as
  suggested by Jeff Layton).

- Introduce nfsd_file_put_local() that will put the reference to the
  nfsd_file's associated nn->nfsd_serv and then put the reference to
  the nfsd_file (as suggested by NeilBrown).

2a33a85be4 nfs_common: add NFS LOCALIO auxiliary protocol enablement
fs/nfs_common/nfslocalio.c provides interfaces that enable an NFS
client to generate a nonce (single-use UUID) and associated nfs_uuid_t
struct, register it with nfs_common for subsequent lookup and
verification by the NFS server and if matched the NFS server populates
members in the nfs_uuid_t struct.

nfs_common's nfs_uuids list is the basis for localio enablement, as
such it has members that point to nfsd memory for direct use by the
client (e.g. 'net' is the server's network namespace, through it the
client can access nn->nfsd_serv).

This commit also provides the base nfs_uuid_t interfaces to allow
proper net namespace refcounting for the LOCALIO use case.

CONFIG_NFS_LOCALIO controls the nfs_common, NFS server and NFS client
enablement for LOCALIO. If both NFS_FS=m and NFSD=m then
NFS_COMMON_LOCALIO_SUPPORT=m and nfs_localio.ko is built (and provides
nfs_common's LOCALIO support).

Add new funtion svcauth_map_clnt_to_svc_cred_local which maps a

Following from net/sunrpc/auth_unix.c:unx_marshal() it is clear that
->fsuid and ->fsgid must be used (rather than ->uid and ->gid).  In
addition, these uid and gid must be translated with from_kuid_munged()
so local client uses correct uid and gid when acting as local server.

Jeff Layton noted:
  This is where the magic happens. Since we're working in

2c8919848d SUNRPC: remove call_allocate() BUG_ONs
Remove BUG_ON if p_arglen=0 to allow RPC with void arg.
Remove BUG_ON if p_replen=0 to allow RPC with void return.

The former was needed for the first revision of the LOCALIO protocol
which had an RPC that took a void arg:

    /* raw RFC 9562 UUID */
    typedef u8 uuid_t<UUID_SIZE>;

    program NFS_LOCALIO_PROGRAM {
        version LOCALIO_V1 {
            void
                NULL(void) = 0;

            uuid_t
                GETUUID(void) = 1;
        } = 1;
    } = 400122;

The latter is needed for the final revision of the LOCALIO protocol
which has a UUID_IS_LOCAL RPC which returns a void:

    /* raw RFC 9562 UUID */
    typedef u8 uuid_t<UUID_SIZE>;

    program NFS_LOCALIO_PROGRAM {
        version LOCALIO_V1 {
            void
                NULL(void) = 0;

            void
                UUID_IS_LOCAL(uuid_t) = 1;
        } = 1;
    } = 400122;

There is really no value in triggering a BUG_ON in response to either
of these previously unsupported conditions.

NeilBrown would like the entire 'if (proc->p_proc != 0)' branch
removed (not just the one BUG_ON that must be removed for LOCALIO's
immediate needs of returning void).
