Pull more xfs updates from Dave Chinner:
"This is the second update for XFS that I mentioned in the original
pull request last week.
It contains a revert for a suspend regression in 4.4 and a fix for a
long standing log recovery issue that has been further exposed by all
the log recovery changes made in the original 4.5 merge.
There is one more thing in this pull request - one that I forgot to
merge into the origin. That is, pulling the XFS_IOC_FS[GS]ETXATTR
ioctl up to the VFS level so that other filesystems can also use it
for modifying project quota IDs
Summary:
- promotion of XFS_IOC_FS[GS]ETXATTR ioctl to the vfs level so that
it can be shared with other filesystems. The ext4 project quota
functionality is the first target for this. The commits in this
series have not been updated with review or final SOB tags because
the branch they were originally published in was needed by ext4.
Those tags are:

NFS on a 2 node ocfs2 cluster each node exporting dir. The lock causing
the hang is the global bit map inode lock. Node 1 is master, has the
lock granted in PR mode; Node 2 is in the converting list (PR -> EX).
There are no holders of the lock on the master node so it should
downconvert to NL and grant EX to node 2 but that does not happen.
BLOCKED + QUEUED in lock res are set and it is on osb blocked list.
Threads are waiting in __ocfs2_cluster_lock on BLOCKED. One thread
wants EX, rest want PR. So it is as though the downconvert thread needs
to be kicked to complete the conv.
The hang is caused by an EX req coming into __ocfs2_cluster_lock on the
heels of a PR req after it sets BUSY (drops l_lock, releasing EX
thread), forcing the incoming EX to wait on BUSY without doing anything.
PR has called ocfs2_dlm_lock, which sets the node 1 lock from NL -> PR,
queues ast.
At this time, upconvert (PR ->EX) arrives from node 2, finds conflict
with node 1 lock in PR, so the lock res is put on dlm thread's dirty
listt.
After ret from ocf2_dlm_lock, PR thread now waits behind EX on BUSY till
awoken by ast.
Now it is dlm_thread that serially runs dlm_shuffle_lists, ast, bast, in
that order. dlm_shuffle_lists ques a bast on behalf of node 2 (which
will be run by dlm_thread right after the ast). ast does its part, sets
UPCONVERT_FINISHING, clears BUSY and wakes its waiters. Next,
dlm_thread runs bast. It sets BLOCKED and kicks dc thread. dc thread
runs ocfs2_unblock_lock, but since UPCONVERT_FINISHING set, skips doing
anything and reques.
Inside of __ocfs2_cluster_lock, since EX has been waiting on BUSY ahead
of PR, it wakes up first, finds BLOCKED set and skips doing anything but
clearing UPCONVERT_FINISHING (which was actually "meant" for the PR
thread), and this time waits on BLOCKED. Next, the PR thread comes out
of wait but since UPCONVERT_FINISHING is not set, it skips updating the
l_ro_holders and goes straight to wait on BLOCKED. So there, we have a
hang! Threads in __ocfs2_cluster_lock wait on BLOCKED, lock res in osb
blocked list. Only when dc thread is awoken, it will run
ocfs2_unblock_lock and things will unhang.
One way to fix this is to wake the dc thread on the flag after clearing
UPCONVERT_FINISHING

rs->begin in ratelimit is set in two cases.
1) when rs->begin was not initialized
2) when rs->interval was passed
For case #2, current ratelimit sets the begin to 0. This incurrs
improper suppression. The begin value will be set in the next ratelimit
call by 1). Then the time interval check will be always false, and
rs->printed will not be initialized. Although enough time passed,
ratelimit may return 0 if rs->printed is not less than rs->burst. To
reset interval properly, begin should be jiffies rather than 0.
For an example code below:
static DEFINE_RATELIMIT_STATE(mylimit, 1, 1);
for (i = 1; i <= 10; i++) {
if (__ratelimit(&mylimit))
printk("ratelimit test count %d\n", i);
msleep(3000);
}
test result in the current code shows suppression even there is 3 seconds sleep.

Tetsuo Handa reported underflow of NR_MLOCK on munlock.
Testcase:
#include <stdio.h>
#include <stdlib.h>
#include <sys/mman.h>
#define BASE ((void *)0x400000000000)
#define SIZE (1UL << 21)
int main(int argc, char *argv[])
{
void *addr;
system("grep Mlocked /proc/meminfo");
addr = mmap(BASE, SIZE, PROT_READ | PROT_WRITE,
MAP_ANONYMOUS | MAP_PRIVATE | MAP_LOCKED | MAP_FIXED,
-1, 0);
if (addr == MAP_FAILED)
printf("mmap() failed\n"), exit(1);
munmap(addr, SIZE);
system("grep Mlocked /proc/meminfo");
return 0;
}
It happens on munlock_vma_page() due to unfortunate choice of nr_pages
data type:
__mod_zone_page_state(zone, NR_MLOCK, -nr_pages);
For unsigned int nr_pages, implicitly casted to long in
__mod_zone_page_state(), it becomes something around UINT_MAX.
munlock_vma_page() usually called for THP as small pages go though
pagevec.
Let's make nr_pages signed int.
Similar fixes in 6cdb18ad98a4 ("mm/vmstat: fix overflow in
mod_zone_page_state()") used `long' type, but `int' here is OK for a
count of the number of sub-pages in a huge page.
Fixes: ff6a6da60b89 ("mm: accelerate munlock() treatment of THP pages")

Expose an interface to allow users to mark several accesses together as
being user space accesses, allowing batching of the surrounding user
space access markers (SMAP on x86, PAN on arm64, domain register
switching on arm).
This is currently only used for the user string lenth and copying
functions, where the SMAP overhead on x86 drowned the actual user
accesses (only noticeable on newer microarchitectures that support SMAP
in the first place, of course).
* user access batching branch:
Use the new batched user accesses in generic user string handling
Add 'unsafe' user access functions for batched accesses

Commit d1cd21427747 ("pwm: Set enable state properly on failed call to
enable") introduced a mutex that is needed to protect internal state of
PWM devices. Since that mutex is acquired in pwm_set_polarity() and in
pwm_enable() and might potentially block, all PWM devices effectively
become "might sleep".
It's rather pointless to keep the .can_sleep field around, but given
that there are external users let's postpone the removal for the next
release cycle.

Pull more power management and ACPI updates from Rafael Wysocki:
"This includes fixes on top of the previous batch of PM+ACPI updates
and some new material as well.
From the new material perspective the most significant are the driver
core changes that should allow USB devices to stay suspended over
system suspend/resume cycles if they have been runtime-suspended
already beforehand. Apart from that, ACPICA is updated to upstream
revision 20160108 (cosmetic mostly, but including one fixup on top of
the previous ACPICA update) and there are some devfreq updates the
didn't make it before (due to timing).
A few recent regressions are fixed, most importantly in the cpuidle
menu governor and in the ACPI backlight driver and some x86 platform
drivers depending on it.
Some more bugs are fixed and cleanups are made on top of that.
Specifics:
- Modify the driver core and the USB subsystem to allow USB devices
to stay suspended over system suspend/resume cycles if they have
been runtime-suspended already beforehand and fix some bugs on top
of these changes (Tomeu Vizoso, Rafael Wysocki).
- Update ACPICA to upstream revision 20160108, including updates of
the ACPICA's copyright notices, a code fixup resulting from a
regression fix that was necessary in the upstream code only (the
regression fixed by it has never been present in Linux) and a
compiler warning fix (Bob Moore, Lv Zheng).
- Fix a recent regression in the cpuidle menu governor that broke it
on practically all architectures other than x86 and make a couple
of optimizations on top of that fix (Rafael Wysocki).
- Clean up the selection of cpuidle governors depending on whether or
not the kernel is configured for tickless systems (Jean Delvare).
- Revert a recent commit that introduced a regression in the ACPI
backlight driver, address the problem it attempted to fix in a
different way and revert one more cosmetic change depending on the
problematic commit (Hans de Goede).
- Add two more ACPI backlight quirks (Hans de Goede).
- Fix a few minor problems in the core devfreq code, clean it up a
bit and update the MAINTAINERS information related to it (Chanwoo
Choi, MyungJoo Ham).
- Improve an error message in the ACPI fan driver (Andy Lutomirski).
- Fix a recent build regression in the cpupower tool (Shreyas
Prabhu)"

Pull ARM SoC multiplatform code updates from Arnd Bergmann:
"This branch is the culmination of 5 years of effort to bring the ARMv6
and ARMv7 platforms together such that they can all be enabled and
boot the same kernel. It has been a tremendous amount of cleanup and
refactoring by a huge number of people, and creation of several new
(and major) subsystems to better abstract out all the platform details
in an appropriate manner.
The bulk of this branch is a large patchset from Arnd that brings
several of the more minor and older platforms we have closer to
multiplatform support. Among these are MMP, S3C64xx, Orion5x, mv78xx0
and realview Much of this is moving around header files from old mach
directories, but there are also some cleanup patches of debug_ll
(lowlevel debug per-platform options) and other parts.
Linus Walleij also has some patchs to clean up the older ARM Realview
platforms by finally introducing DT support, and Rob Herring has some
for ARM Versatile which is now DT-only. Both of these platforms are
now multiplatform.
Finally, a couple of patches from Russell for Dove PMU, and a fix from
Valentin Rothberg for Exynos ADC, which were rebased on top of the
series to avoid conflicts"

Pull SCSI target updates from Nicholas Bellinger:
"The highlights this round include:
- Introduce configfs support for unlocked configfs_depend_item()
(krzysztof + andrezej)
- Conversion of usb-gadget target driver to new function registration
interface (andrzej + sebastian)
- Enable qla2xxx FC target mode support for Extended Logins (himansu +
giridhar)

get_initiator_node_acl() lookup. (hch + nab)
- Fix target/user block-size handling, and make sure netlink reaches
all network namespaces (sheng + andy)
Note there is an outstanding bug-fix series for remote I_T nexus port
TMR LUN_RESET has been posted and still being tested, and will likely
become post -rc1 material at this point"

Larry Finger reports:
"My PowerBook G4 Aluminum with a 32-bit PPC processor fails to boot for
the 4.4-git series".
This is likely due to X still needing /dev/mem access on this platform.
CONFIG_IO_STRICT_DEVMEM is not yet safe to turn on when
CONFIG_STRICT_DEVMEM=y.
Remove the default so that old configurations do not change behavior.
Fixes: 90a545e98126 ("restrict /dev/mem to idle io memory ranges")

Changing page->mem_cgroup of a live page is tricky and fragile. In
particular, the memcg writeback code relies on that mapping being stable
and users of mem_cgroup_replace_page() not overlapping with dirtyable
inodes.
Page cache replacement doesn't have to do that, though. Instead of being
clever and transferring the charge from the old page to the new,
force-charge the new page and leave the old page alone. A temporary
overcharge won't matter in practice, and the old page is going to be freed
shortly after this anyway. And this is not performance critical.

Swap cache pages are freed aggressively if swap is nearly full (>50%
currently), because otherwise we are likely to stop scanning anonymous
when we near the swap limit even if there is plenty of freeable swap cache
pages. We should follow the same trend in case of memory cgroup, which
has its own swap limit.

The following patches will add more functions to the memcg section of
include/linux/swap.h. Some of them will need values defined below the
current location of the section. So let's move the section to the end of
the file. No functional changes intended.

mem_cgroup_lruvec_online() takes lruvec, but it only needs memcg. Since
get_scan_count(), which is the only user of this function, now possesses
pointer to memcg, let's pass memcg directly to mem_cgroup_online() instead
of picking it out of lruvec and rename the function accordingly.

memcg will come in handy in get_scan_count(). It can already be used for
getting swappiness immediately in get_scan_count() instead of passing it
around. The following patches will add more memcg-related values, which
will be used there.
