/dev/oldmem: Remove the interface
/dev/oldmem provides the interface for us to access the "old memory" in the dump-capture kernel. Unfortunately, no one actually uses this interface. And this interface could actually cause some real problems if used on ia64 where the cached/uncached accesses are mixed. See the discussion from the link: https://lkml.org/lkml/2013/4/12/386. So Eric suggested that we should remove /dev/oldmem as an unused piece of code. [akpm@linux-foundation.org: mention /dev/oldmem obsolescence in devices.txt] Suggested-by: "Eric W.

rtc: add ability to push out an existing wakealarm using sysfs
This adds the ability for the rtc sysfs code to handle += characters at the beginning of a wakealarm setting string. This will allow the user to attempt to push out an existing wakealarm by a provided amount. In the case that the += characters are provided but the alarm is not active -EINVAL is returned. his is useful, at least for my purposes in suspend/resume testing. The basic test goes something like: 1. Set a wake alarm from userspace 5 seconds in the future 2. Start the suspend process (echo mem > /sys/power/state) 3. After ~2.5 seconds if userspace is still running (using another thread to check this), move the wake alarm 5 more seconds If the "move" involves an unset of the wakealarm then there's a period of time where the system is midway through suspending but has no wake alarm. It will get stuck. We'd rather not remove the "move" since the idea is to avoid a cancelled suspend when the alarm fires _during_ suspend. It is difficult for the test to tell the difference between a suspend that was cancelled because the alarm fired too early and a suspend that was Signed-off-by: Bernie Thompson <bhthompson@chromium.org> Cc: Alessandro Zummo <a.zummo@towertech.it> Cc: Doug Anderson <dianders@chromium.org> Cc: "Rafael J.

pagemap: prepare to reuse constant bits with page-shift
In order to reuse bits from pagemap entries gracefully, we leave the entries as is but on pagemap open emit a warning in dmesg, that bits 55-60 are about to change in a couple of releases. Next, if a user issues soft-dirty clear command via the clear_refs file (it was disabled before v3.9) we assume that he's aware of the new pagemap format, note that fact and report the bits in pagemap in the new manner. The "migration strategy" looks like this then: 1. existing users are not affected -- they don't touch soft-dirty feature, thus see old bits in pagemap, but are warned and have time to fix themselves 2. those who use soft-dirty know about new pagemap format 3. some time soon we get rid of any signs of page-shift in pagemap as well as this trick with clear-soft-dirty affecting pagemap format.

mm: soft-dirty bits for user memory changes tracking
The soft-dirty is a bit on a PTE which helps to track which pages a task
writes to. In order to do this tracking one should
1. Clear soft-dirty bits from PTEs ("echo 4 > /proc/PID/clear_refs)
2. Wait some time.
3. Read soft-dirty bits (55'th in /proc/PID/pagemap2 entries)
To do this tracking, the writable bit is cleared from PTEs when the
soft-dirty bit is. Thus, after this, when the task tries to modify a
page at some virtual address the #PF occurs and the kernel sets the
soft-dirty bit on the respective PTE.
Note, that although all the task's address space is marked as r/o after
the soft-dirty bits clear, the #PF-s that occur after that are processed
fast. This is so, since the pages are still mapped to physical memory,
and thus all the kernel does is finds this fact out and puts back
writable, dirty and soft-dirty bits on the PTE.
Another thing to note, is that when mremap moves PTEs they are marked
with soft-dirty as well, since from the user perspective mremap modifies
the virtual memory at mremap's new address.

Merge branch 'for-linus' of git://git.linaro.org/people/rmk/linux-arm
Pull ARM updates from Russell King:
"This contains the usual updates from other people (listed below) and
the usual random muddle of miscellaneous ARM updates which cover some
low priority bug fixes and performance improvements.
I've started to put the pull request wording into the merge commits,
which are:
- NoMMU stuff:
This includes the following series sent earlier to the list:
- nommu-fixes
- R7 Support
- MPU support
I've left out the ARCH_MULTIPLATFORM/!MMU stuff that Arnd and I
were discussing today until we've reached a conclusion/that's had
some more review.
This is rebased (and re-tested) on your devel-stable branch because
otherwise there were going to be conflicts with Uwe's V7M work now
that you've merged that. I've included the fix for limiting MPU to
CPU_V7.
- Huge page support
These changes bring both HugeTLB support and Transparent HugePage
(THP) support to ARM. Only long descriptors (LPAE) are supported
in this series.
The code has been tested on an Arndale board (Exynos 5250).
- LPAE updates
Please pull these miscellaneous LPAE fixes I've been collecting for
a while now for 3.11. They've been tested and reviewed by quite a
few people, and most of the patches are pretty trivial. -- Will Deacon.
- arch_timer cleanups
Please pull these arch_timer cleanups I've been holding onto for a
while. They're the same as my last posting, but have been rebased
to v3.10-rc3.
- mpidr linearisation (multiprocessor id register - identifies which
CPU number we are in the system)
This patch series that implements MPIDR linearization through a
simple hashing algorithm and updates current cpu_{suspend}/{resume}
code to use the newly created hash structures to retrieve context
pointers. It represents a stepping stone for the implementation of
power management code on forthcoming multi-cluster ARM systems.
It has been tested on TC2 (dual cluster A15xA7 system), iMX6q,
OMAP4 and Tegra, with processors hitting low-power states requiring
warm-boot resume through the cpu_resume code path"

Pull workqueue changes from Tejun Heo: "Surprisingly, Lai and I didn't break too many things implementing custom pools and stuff last time around and there aren't any follow-up changes necessary at this point. The only change in this pull request is Viresh's patches to make some per-cpu workqueues to behave as unbound workqueues dependent on a boot param whose default can be configured via a config option. This leads to higher processing overhead / lower bandwidth as more work items are bounced across CPUs; however, it can lead to noticeable powersave in certain configurations - ~10% w/ idlish constant workload on a big.LITTLE configuration according to Viresh. This is because per-cpu workqueues interfere with how the scheduler perceives whether or not each CPU is idle by forcing pinned tasks on them, which makes the scheduler's power-aware scheduling decisions less effective. Its effectiveness is likely less pronounced on homogenous configurations and this type of optimization can probably be made automatic; however, the changes are pretty minimal and the affected workqueues are clearly marked, so it's an easy gain for some configurations for the time being with pretty unintrusive changes." * 'for-3.11' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq: fbcon: queue work on power efficient wq block: queue work on power efficient wq PHYLIB: queue work on system_power_efficient_wq workqueue: Add system wide power_efficient workqueues workqueues: Introduce new flag WQ_POWER_EFFICIENT for power oriented workqueues |

Merge branch 'core-mutexes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull WW mutex support from Ingo Molnar:
"This tree adds support for wound/wait style locks, which the graphics
guys would like to make use of in the TTM graphics subsystem.
Wound/wait mutexes are used when other multiple lock acquisitions of a
similar type can be done in an arbitrary order. The deadlock handling
used here is called wait/wound in the RDBMS literature: The older
tasks waits until it can acquire the contended lock. The younger
tasks needs to back off and drop all the locks it is currently
holding, ie the younger task is wounded.
See this LWN.net description of W/W mutexes:
https://lwn.net/Articles/548909/
The comments there outline specific usecases for this facility (which
have already been implemented for the DRM tree).
Also see Documentation/ww-mutex-design.txt for more details"

ARM SoC late changes
These are changes that arrived a little late before the merge
window or that have multiple dependencies on previous branches
so they did not fit into one of the earlier ones. There
are 10 branches merged here, a total of 39 non-merge commits.
Contents are a mixed bag for the above reasons:
* Two new SoC platforms: ST microelectronics stixxxx and
the TI 'Nspire' graphing calculator. These should have
been in the 'soc' branch but were a little late
* Support for the Exynos 5420 variant in mach-exynos,
which is based on the other exynos branches to avoid
conflicts.
* Various small changes for sh-mobile, ux500 and davinci
* Common clk support for MSM
Conflicts:
* In Kconfig.debug, various additions trivially conflict,
the list should be kept in alphabetical order when
resolving.

ARM SoC driver specific changes
These changes are all driver specific and cross over between arm-soc contents and some other subsystem, in these cases cpufreq, crypto, dma, pinctrl, mailbox and usb, and the subsystem owners agreed to have these changes merged through arm-soc. As we proceed to untangle the dependencies between platform code and driver code, the amount of changes in this category is fortunately shrinking, for 3.11 we have 16 branches here and 101 non-merge changesets, the majority of which are for the stedma40 dma engine driver used in the ux500 platform. Cleaning up that code touches multiple subsystems, but gets rid of the dependency in the end. The mailbox code moved out from mach-omap2 to drivers/mailbox is an intermediate step and is still omap specific at the moment. Patches exist to generalize the subsystem and add other drivers with the same API, but those did not make it for 3.11. Conflicts: * In cpu-db8500.c results from the removal of the u8500_of_init_devices function in combination with the split of u8500_auxdata_lookup. * In arch/arm/mach-omap2/devices.c, the includes got reshuffled. we need to keep linux/wl12xx.h and linux/platform_data/mailbox-omap.h. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iQIVAwUAUdLnomCrR//JCVInAQJI/A/9FydsQa9sdnzLFgcdX5BeRRwkXLfDifCM zDTfUBo+LriKOs7QHblmDg1MnY1UMB2IfrdHD0FsjK7WbZ/91EMAGDPYcI7Fu4+u pGStxwWi2v+oCT1jjeOkCPT7hdCqogsSpybYq8itSb+zdvdOi6U35dWEKz8xGqz4 vTL9gTZbJP0kowkjIcaryk7FIj7BTIvMCW8n55JZEkDe0BuSJGYn5c3Mntut12ZK 5xM2PeNe2sd3dIdA6XbM2ye/XmYa8xY8Qu4/ijxfH1gnJLvz9Unp96nRXpEbIeMb BH2Sro8dxsMCaweIQhSRKGnUWMYO/Rh7/+5EqzJ163Ezthx9nvHXJY2ndWuD7uM1 IcGrMxLtqP22TEMtZAVEATDp/5ymxEo5GM+eayUojQDn213wOJjRs5xz5IBsH4KM 8CM/gpadWmLjWku72yEV4lryLcdS0NVQzpTnEbILEGOU4u7qJtxRAp7x7tWBtFg8 4m/eWcSVk/U2SYbXmQHsfukuWgKY0cnZbctPcdnaqXwTP7toJEAK3gxoMtWh49Jq 2M2PVFyFejaaq5b/71wAJ7ePYw56H0N/F3RsGpPE55AY15++gSoQ+3t2Si68hDw8 NtyJMkQYpTvtqJbHXWpQQ3Zfs7pDBe01WDV7i+m4JTNggxUDaO/t1Fqp+fEksm4J r+luEf5Gcgk= =mJsI -----END PGP SIGNATURE----- Merge tag 'drivers-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC driver specific changes from Arnd Bergmann: "These changes are all driver specific and cross over between arm-soc contents and some other subsystem, in these cases cpufreq, crypto, dma, pinctrl, mailbox and usb, and the subsystem owners agreed to have these changes merged through arm-soc.

ARM SoC device tree changes
These changes from 30 individual branches for the most part update device tree files, but there are also a few source code changes that have crept in this time, usually in order to atomically move over a driver from using hardcoded data to DT probing. A number of platforms change their DT files to use the C preprocessor, which is causing a bit of churn, but that is hopefully only this once. There are a few conflicts with the other branches unfortunately: * in exynos5440.dtsi and kirkwood-6281.dtsi, device nodes are added from multiple branches. Need to be careful to have the right set of closing braces as git gets this one wrong. * In kirkwood.dtsi, one 'ranges' line got split into two lines, while another line got added. Order of the lines does not matter. * in sama5d3.dtsi, some cleanup was merged the wrong way, causing a bogus conflict. We want the 'dmas' and 'dma-names' properties to get added here. * Two lines got removed independently in arch/arm/mach-mxs/mach-mxs.c * Contents get added independently in arch/arm/mach-omap2/cclock33xx_data.c -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iQIVAwUAUdLnpGCrR//JCVInAQI50RAAsXbH1SGvjKJemXhRkFloPDYpCbgdDUFr ChUbjNV1xsY/jaNCfMa5/Qo7lgz/Ot7BpJef9fZn7ret+dc7nchqe/4iIkAokAUh E4ao9D1dP5aAA0ihdbSQHCZtR/0SUR81h6BoOVuo/1mvEiBaFbWAeYe8/6LJd9II OU1w9bDmjfZWYFUXs+j2VF76ueZQ+kz69XDKZUGtkqN76m1AL8lGDurj5jxvyllF VJns8d9q2nr2q9PferfajK6rkOIPaTpwKblxZHUgobCyOitZaiZM0NgF733TsNM6 HXmhDhkcn7T81+SiHVfigJ/nxo9UgU4zNJCODF3WZIwGIj3FbxvCOpdCYi2NhCO8 oLcgDk57tpoKpB3gvAmYVQHP9FIepFa/WAWyPIADA7PkpYrwgc4v+cLEHXpd8SRv viLLIa5QuNdMeaK+Md9OKmKZFd7uFD9jiMtmdm6IpEVDDjMgoteb2XSoEtNebmtY MfbW4okn118a2dFKKaPTKcXVW/a5FRp2JGfB0A58RQHaJWj3JsY1bFn/xWPEpTOA IWB/HHMln0LYTL2AXN9HcaL1jnGI1Wq5eWBurX+cXQ/ij1A6jfoRKYglx7AQqOHj iWcGYtKLLJCgiWFnLSwcljZhfoYr0/z7rhns6yo7/vhN0riy+M84OgN4HbAmUzc1 Bgy9PnJTNo8= =8PtJ -----END PGP SIGNATURE----- Merge tag 'dt-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC device tree changes from Arnd Bergmann: "These changes from 30 individual branches for the most part update device tree files, but there are also a few source code changes that have crept in this time, usually in order to atomically move over a driver from using hardcoded data to DT probing.

ARM SoC specific changes
These changes are all to SoC-specific code, a total of 33 branches on 17 platforms were pulled into this. Like last time, Renesas sh-mobile is now the platform with the most changes, followed by OMAP and EXYNOS. Two new platforms, TI Keystone and Rockchips RK3xxx are added in this branch, both containing almost no platform specific code at all, since they are using generic subsystem interfaces for clocks, pinctrl, interrupts etc. The device drivers are getting merged through the respective subsystem maintainer trees. One more SoC (u300) is now multiplatform capable and several others (shmobile, exynos, msm, integrator, kirkwood, clps711x) are moving towards that goal with this series but need more work. Also noteworthy is the work on PCI here, which is traditionally part of the SoC specific code. With the changes done by Thomas Petazzoni, we can now more easily have PCI host controller drivers as loadable modules and keep them separate from the platform code in drivers/pci/host. This has already led to the discovery that three platforms (exynos, spear and imx) are actually using an identical PCIe host controller and will be able to share a driver once support for spear and imx is added.

ARM SoC cleanups

Lots of bug fixes, cleanups and optimizations. In the bug fixes
category, of note is a fix for on-line resizing file systems where the block size is smaller than the page size (i.e., file systems 1k blocks on x86, or more interestingly file systems with 4k blocks on Power or ia64 systems.) In the cleanup category, the ext4's punch hole implementation was significantly improved by Lukas Czerner, and now supports bigalloc file systems. In addition, Jan Kara significantly cleaned up the write submission code path. We also improved error checking and added a few sanity checks. In the optimizations category, two major optimizations deserve mention. The first is that ext4_writepages() is now used for nodelalloc and ext3 compatibility mode. This allows writes to be submitted much more efficiently as a single bio request, instead of being sent as individual 4k writes into the block layer (which then relied on the elevator code to coalesce the requests in the block queue). Secondly, the extent cache shrink mechanism, which was introduce in 3.9, no longer has a scalability bottleneck caused by the i_es_lru spinlock. Other optimizations include some changes to reduce CPU usage and to avoid issuing empty commits unnecessarily. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iQIcBAABCAAGBQJR0XhgAAoJENNvdpvBGATwMXkQAJwTPk5XYLqtAwLziFLvM6wG 0tWa1QAzTNo80tLyM9iGqI6x74X5nddLw5NMICUmPooOa9agMuA4tlYVSss5jWzV yyB7vLzsc/2eZJusuVqfTKrdGybE+M766OI6VO9WodOoIF1l51JXKjktKeaWegfv NkcLKlakD4V+ZASEDB/cOcR/lTwAs9dQ89AZzgPiW+G8Do922QbqkENJB8mhalbg rFGX+lu9W0f3fqdmT3Xi8KGn3EglETdVd6jU7kOZN4vb5LcF5BKHQnnUmMlpeWMT ksOVasb3RZgcsyf5ZOV5feXV601EsNtPBrHAmH22pWQy3rdTIvMv/il63XlVUXZ2 AXT3cHEvNQP0/yVaOTCZ9xQVxT8sL4mI6kENP9PtNuntx7E90JBshiP5m24kzTZ/ zkIeDa+FPhsDx1D5EKErinFLqPV8cPWONbIt/qAgo6663zeeIyMVhzxO4resTS9k U2QEztQH+hDDbjgABtz9M/GjSrohkTYNSkKXzhTjqr/m5huBrVMngjy/F4/7G7RD vSEx5aXqyagnrUcjsupx+biJ1QvbvZWOVxAE/6hNQNRGDt9gQtHAmKw1eG2mugHX +TFDxodNE4iWEURenkUxXW3mDx7hFbGZR0poHG3M/LVhKMAAAw0zoKrrUG5c70G7 XrddRLGlk4Hf+2o7/D7B =SwaI -----END PGP SIGNATURE----- Merge tag 'ext4_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4 Pull ext4 update from Ted Ts'o: "Lots of bug fixes, cleanups and optimizations.

locks: give the blocked_hash its own spinlock
There's no reason we have to protect the blocked_hash and file_lock_list with the same spinlock. With the tests I have, breaking it in two gives a barely measurable performance benefit, but it seems reasonable to make this locking as granular as possible.

locks: add a new "lm_owner_key" lock operation
Currently, the hashing that the locking code uses to add these values to the blocked_hash is simply calculated using fl_owner field. That's valid in most cases except for server-side lockd, which validates the owner of a lock based on fl_owner and fl_pid. In the case where you have a small number of NFS clients doing a lot of locking between different processes, you could end up with all the blocked requests sitting in a very small number of hash buckets. Add a new lm_owner_key operation to the lock_manager_operations that will generate an unsigned long to use as the key in the hashtable. That function is only implemented for server-side lockd, and simply XORs the fl_owner and fl_pid. Signed-off-by: Jeff Layton <jlayton@redhat.com> Acked-by: J.

locks: protect most of the file_lock handling with i_lock
Having a global lock that protects all of this code is a clear scalability problem. Instead of doing that, move most of the code to be protected by the i_lock instead. The exceptions are the global lists that the ->fl_link sits on, and the ->fl_block list. ->fl_link is what connects these structures to the global lists, so we must ensure that we hold those locks when iterating over or updating these lists. Furthermore, sound deadlock detection requires that we hold the blocked_list state steady while checking for loops. We also must ensure that the search and update to the list are atomic. For the checking and insertion side of the blocked_list, push the acquisition of the global lock into __posix_lock_file and ensure that checking and update of the blocked_list is done without dropping the lock in between. On the removal side, when waking up blocked lock waiters, take the global lock before walking the blocked list and dequeue the waiters from the global list prior to removal from the fl_block list. With this, deadlock detection should be race free while we minimize excessive file_lock_lock thrashing. Finally, in order to avoid a lock inversion problem when handling /proc/locks output we must ensure that manipulations of the fl_block list are also protected by the file_lock_lock.

Don't pass inode to ->d_hash() and ->d_compare()
Instances either don't look at it at all (the majority of cases) or only want it to find the superblock (which can be had as dentry->d_sb). A few cases that want more are actually safe with dentry->d_inode - the only precaution needed is the check that it hadn't been replaced with NULL by rmdir() or by overwriting rename(), which case should be simply treated as cache miss.

[readdir] introduce iterate_dir() and dir_context
iterate_dir(): new helper, replacing vfs_readdir(). struct dir_context: contains the readdir callback (and will get more stuff in it), embedded into whatever data that callback wants to deal with; eventually, we'll be passing it to ->readdir() replacement instead of (data,filldir) pair.

Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull networking fixes from David Miller:
1) Found via trinity:
If you connect up an ipv6 socket to an ipv4 mapped address then an
ipv6 one, sendmsg() can croak because ip6_sk_dst_check() assumes the
route cached in the socket is an ipv6 one. In this case there is an
ipv4 route attached, so it gets stomped on.
Reported by Dave Jones and Hannes Frederic Sowa, fixed by Eric
Dumazet.
2) AF_KEY notifications leak some kernel memory to userspace, fix from
Mathias Krause.
3) DLCI calls __dev_get_by_name() without proper locking, and dlci_del
doesn't validate that the device being deleted is actually a DLCI
one. Fixes from Li Zefan.
4) Length check on bluetooth l2cap information responses is wrong, each
response type has a different lenth, so we should make sure it's in
a given range rather than enforce one single valid length. From
Jaganath Kanakkassery.
5) Receive FIFO overflow is really easy to trigger in stress scenerios
in the sh_eth driver, but the event isn't being handled properly at
all. Specifically, the mask of error interrupts doesn't include the
event so we never clear it, resulting in the driver becomming wedged
processing an interrupt that never gets cleared.
Fix from Sergei Shtylyov.
6) qlcnic sleeps while holding a spinlock, use mdelay() instead of
msleep(). From Shahed Shaikh.
7) Missing curly braces causes SIP netfilter NAT module to always drop
packets. Fix from Balazs Peter Odor.
8) ipt_ULOG in netfilter passes the wrong value to timer setup, causing
the timer to dereference crap when it fires. Fix from Gao Feng.
9) Missing RCU protection around txq->axq_acq traversal in
ath_txq_schedule(). Fix from Felix Fietkau.
10) Idle state transition test in ath9k_htc_config() is reversed, fix
from Sujith Manoharan.
11) IPV6 forwarding handles unicast Router Alert packets incorrectly.
It tests the wrong option state. Previously opt->ra being non-zero
indicated a router alert marking in the SKB, but now it's indicated
by a bit in opt->flags. Fix from YOSHIFUJI Hideaki.
12) SKB leak in GRE tunnel GSO handling, from Eric Dumazet.
13) get_user_pages_fast() error handling in TUN and MACVTAP use the same
local variable for the base index and the loop iterator for page
traversal, oops! Fix from Michael S Tsirkin.
14) ipv6_get_lladdr() can fail, and we must therefore check it's return
value in inet6_set_iftoken(). For from Hannes Frederic Sowa.
15) If you change an interface name and meanwhile can sneak in something
that looks up the name (like SO_BINDTODEVICE or SIOCGIFNAME) we can
deadlock with CONFIG_PREEMPT=n. Fix this by providing a helper
function that properly uses raw_seqcount_begin(). From Nicolas
Schichan.
16) Chain noise calibration test is inverted in iwlwifi, fix from
Nikolay Martynov.
17) Properly set TX iwlwifi descriptor flags for back requests. Fix
from Emmanuel Grumbach.
18) We can't assume skb_transport_header() is set in xt_TCPOPTSTRAP
module, fix from Pablo Neira Ayuso.
19) Some crummy APs don't provide the proper High Throughput info in
association response frames. Add a workaround by assume we'll use
whatever is in the beacon/probe. Fix from Johannes Berg.
20) mac80211 call to rate_idx_match_mask() swaps two arguments (mask and
channel width). Fix from Simon Wunderlich.
21) xt_TCPMSS (like xt_TCPOPTSTRAP) must not try to handle fragmented
frames. Fix from Phil Oester.
22) Fix rate control regression causing iwlwifi/iwlegacy chips to use
1Mbit/s on pre-11n networks. From Moshe Benji and Stanslaw Gruszka.
23) Disable brcmsmac power-save functions, they cause regressions. From
Arend van Spriel.
24) Enforce a sane minimum MTU in l2cap_build_cmd() otherwise we can
easily crash. Fix from Anderson Lizardo.
25) If a learning packet arrives during vxlan_stop() we crash, easily
fixed by checking netif_running(). From Stephen Hemminger.
26) Static vxlan FDB entries should not be migrated, also from Stephen.
27) skb_clone() failures not handled in vxlan_xmit(), oops. Also from
Stephen.
28) Add minimal driver for AR816x/AR817x ethernet chips, from Johannes
Berg.
29) Fix regression in userspace VLAN acceleration control, added by the
802.1ad support changes. Fix from Fernando Luis Vazquez Cao.
30) Interval selection for MLD queries in the bridging code was
reversed. Fix from Linus Lüssing.
31) ipv6's ndisc_send_redirect() erroneously writes to the packet we
received not the packet we are building to send out. Fix from
Matthias Schiffer.
32) Don't free netdev before unregistering it, in usb_8dev can driver.
From Marc Kleine-Budde.
33) Fix nl80211 attribute buffer races, from Johannes Berg.
34) Although netlink_diag.h is under uapi/ it isn't present in Kbuild.
From Stephen Hemminger.
35) Wrong address and family passed to MD5 key lookups in TCP, from
Aydin Arik.
36) phy_type attribute created by SFC driver should not be writable.
From Ben Hutchings.
37) Receive/Transmit queue allocations in pxa168_eth and mv643xx_eth
should use kzalloc(). Otherwise if setup fails half-way, we'll
dereference garbage when trying to teardown the rings. From Lubomir
Rintel.
38) Fix double-allocation of dst (resulting in unfreeable net device) in
ipv6's init_loopback(). From Gao Feng.
39) Fix fragmentation handling SKB leak in netfilter conntrack, we were
freeing the wrong skb pointer. From Phil Oester.
40) Don't report "-1" (SPEED_UNKNOWN) in bond_miimon_commit(), from
Nikolay Aleksandrov.
41) davinci_cpdma doesn't check for DMA mapping errors, letting the
device scribble to random addresses. From Sebastian Siewior.

mutex: Add support for wound/wait style locks
Wound/wait mutexes are used when other multiple lock acquisitions of a similar type can be done in an arbitrary order. The deadlock handling used here is called wait/wound in the RDBMS literature: The older tasks waits until it can acquire the contended lock. The younger tasks needs to back off and drop all the locks it is currently holding, i.e. the younger task is wounded. For full documentation please read Documentation/ww-mutex-design.txt.

Merge branch 'sti/soc' into next/late
From Srinivas Kandagatla <srinivas.kandagatla@st.com>: This patch-set adds basic support for STMicroelectronics STi series SOCs which includes STiH415 and STiH416 with B2000 and B2020 board support. STiH415 and STiH416 are dual-core ARM Cortex-A9 CPU, designed for use in Set-top-boxes. The SOC support is available in mach-sti which contains support code for STiH415, STiH416 SOCs including the generic board support. The reason for adding two SOCs at this patch set is to show that no new C code is required for second SOC(STiH416) support. * sti/soc: ARM: stih41x: Add B2020 board support ARM: stih41x: Add B2000 board support ARM: sti: Add DEBUG_LL console support ARM: sti: Add STiH416 SOC support ARM: sti: Add STiH415 SOC support Signed-off-by: Olof Johansson <olof@lixom.net> |
