Current implementation of HFS+ driver has small issue with remount
option.  Namely, for example, you are unable to remount from RO mode
into RW mode by means of command "mount -o remount,rw /dev/loop0
/mnt/hfsplus".  Trying to execute sequence of commands results in an
error message:

  mount /dev/loop0 /mnt/hfsplus
  mount -o remount,ro /dev/loop0 /mnt/hfsplus
  mount -o remount,rw /dev/loop0 /mnt/hfsplus

  mount: you must specify the filesystem type

  mount -t hfsplus -o remount,rw /dev/loop0 /mnt/hfsplus

  mount: /mnt/hfsplus not mounted or bad option

The reason of such issue is failure of mount syscall:

  mount("/dev/loop0", "/mnt/hfsplus", 0x2282a60, MS_MGC_VAL|MS_REMOUNT, NULL) = -1 EINVAL (Invalid argument)

Namely, hfsplus_parse_options_remount() method receives empty "input"
argument and return false in such case.  As a result, hfsplus_remount()
returns -EINVAL error code.

This patch fixes the issue by means of return true for the case of empty
"input" argument in hfsplus_parse_options_remount() method.

Commit bcf24e1d ("mmc: omap_hsmmc: use the generic config for
omap2plus devices"), enabled the build for other platforms for compile
testing.

sh-allmodconfig now fails with:

    include/linux/omap-dma.h:171:8: error: expected identifier before numeric constant
    make[4]: *** [drivers/mmc/host/omap_hsmmc.o] Error 1

This happens because SuperH #defines "CCR", which is one of the enum
values in include/linux/omap-dma.h.  There's a similar issue with "CCR2"
on sh2a.

As "CCR" and "CCR2" are too generic names for global #defines, prefix
them with "SH_" to fix this.

Global quota files are accessed from different nodes.  Thus we cannot
cache offset of quota structure in the quota file after we drop our node
reference count to it because after that moment quota structure may be
freed and reallocated elsewhere by a different node resulting in
corruption of quota file.

Fix the problem by clearing dq_off when we are releasing dquot structure.
We also remove the DB_READ_B handling because it is useless -
DQ_ACTIVE_B is set iff DQ_READ_B is set.

Currently symbols that are absolute addresses are incorrectly displayed
in /proc/kallsyms if the kernel is loaded with kASLR.

The problem was that the scripts/kallsyms.c file which generates the
array of symbol names and addresses uses an relocatable value for all
symbols, even absolute symbols.  This patch fixes that.

Several kallsyms output in different boot states for comparison:

LZ4 as implemented in the kernel differs from the default method now

because munlock_vma_pages_range() thinks it's unexpectedly in the middle
of a THP page.  This can be reproduced with default config since 3.11
kernels.  A reproducer can be found in the kernel's selftest directory
for networking by running ./psock_tpacket.

The problem is that an order=2 compound page (allocated by
alloc_one_pg_vec_page() is part of the munlocked VM_MIXEDMAP vma (mapped
by packet_mmap()) and mistaken for a THP page and assumed to be order=9.

The checks for THP in munlock came with commit ff6a6da6 ("mm:
accelerate munlock() treatment of THP pages"), i.e.  since 3.9, but did
not trigger a bug.  It just makes munlock_vma_pages_range() skip such
compound pages until the next 512-pages-aligned page, when it encounters
a head page.  This is however not a problem for vma's where mlocking has
no effect anyway, but it can distort the accounting.

Since commit 7225522b ("mm: munlock: batch non-THP page isolation
and munlock+putback using pagevec") this can trigger a VM_BUG_ON in
PageTransHuge() check.

This patch fixes the issue by adding VM_MIXEDMAP flag to VM_SPECIAL, a
list of flags that make vma's non-mlockable and non-mergeable.  The
reasoning is that VM_MIXEDMAP vma's are similar to VM_PFNMAP, which is
already on the VM_SPECIAL list, and both are intended for non-LRU pages
where mlocking makes no sense anyway.  Related Lkml discussion can be
found in [2].

Sometimes the cleanup after memcg hierarchy testing gets stuck in
mem_cgroup_reparent_charges(), unable to bring non-kmem usage down to 0.

There may turn out to be several causes, but a major cause is this: the
workitem to offline parent can get run before workitem to offline child;
parent's mem_cgroup_reparent_charges() circles around waiting for the
child's pages to be reparented to its lrus, but it's holding
cgroup_mutex which prevents the child from reaching its
mem_cgroup_reparent_charges().

Further testing showed that an ordered workqueue for cgroup_destroy_wq
is not always good enough: percpu_ref_kill_and_confirm's call_rcu_sched
stage on the way can mess up the order before reaching the workqueue.

Instead, when offlining a memcg, call mem_cgroup_reparent_charges() on
all its children (and grandchildren, in the correct order) to have their
charges reparented first.

d8ad3055 ("mm/memcg: iteration skip memcgs not yet fully

It's elusive, and harder to get than the original, but for a couple of
days before rc1, I several times saw a endless loop similar to that
supposedly being fixed.

This time it was a tighter loop in __mem_cgroup_iter_next(): because we
can get here when our root has already been offlined, and the ordering
of conditions was such that we then just cycled around forever.

While debug_dma_assert_idle() checks if a given *page* is actively
undergoing dma the valid granularity of a dma mapping is a *cacheline*.
Sander's testing shows that the warning message "DMA-API: exceeded 7
overlapping mappings of pfn..." is falsely triggering.  The test is
simply mapping multiple cachelines in a given page.

Ultimately we want overlap tracking to be valid as it is a real api
violation, so we need to track active mappings by cachelines.  Update
the active dma tracking to use the page-frame-relative cacheline of the
mapping as the key, and update debug_dma_assert_idle() to check for all
possible mapped cachelines for a given page.

However, the need to track active mappings is only relevant when the
dma-mapping is writable by the device.  In fact it is fairly standard
for read-only mappings to have hundreds or thousands of overlapping
mappings at once.  Limiting the overlap tracking to writable
(!DMA_TO_DEVICE) eliminates this class of false-positive overlap
reports.

Note, the radix gang lookup is sub-optimal.  It would be best if it
stopped fetching entries once the search passed a page boundary.
Nevertheless, this implementation does not perturb the original net_dma
failing case.  That is to say the extra overhead does not show up in
terms of making the failing case pass due to a timing change.

Commit bf6bddf1 ("mm: introduce compaction and migration for
ballooned pages") introduces page_count(page) into memory compaction
which dereferences page->first_page if PageTail(page).

This results in a very rare NULL pointer dereference on the
aforementioned page_count(page).  Indeed, anything that does
compound_head(), including page_count() is susceptible to racing with
prep_compound_page() and seeing a NULL or dangling page->first_page
pointer.

This patch uses Andrea's implementation of compound_trans_head() that
deals with such a race and makes it the default compound_head()
implementation.  This includes a read memory barrier that ensures that
if PageTail(head) is true that we return a head page that is neither
NULL nor dangling.  The patch then adds a store memory barrier to
prep_compound_page() to ensure page->first_page is set.

This is the safest way to ensure we see the head page that we are
expecting, PageTail(page) is already in the unlikely() path and the
memory barriers are unfortunately required.

Hugetlbfs is the exception, we don't enforce a store memory barrier
during init since no race is possible.

 "These three commits fix a recent intel_pstate regression and two old
  bugs that should be fixed in -stable too, one in the ACPI processor
  driver and one in the firmare loader.

  Specifics:

   - One of the recent intel_pstate driver fixes introduced a rounding
     error that on some systems causes the frequency to be stuck at the
     lowest level forever.  Fix from Dirk Brandewie.

   - The firmware_class driver's PM notifier doesn't handle the
     PM_RESTORE_PREPARE event during hibernation image restore and that
     leads to a deadlock on umhelper_sem in __usermodehelper_disable().
     Fix from Sebastian Capella.

   - acpi_processor_set_throttling() abuses set_cpus_allowed_ptr() in a
     nasty way which triggers the WARN_ON_ONCE() in wq_worker_waking_up()
     among other things.  Fix from Lan Tianyu"

Jonathan writes:

Fourth set of IIO fixes for the 3.14 kernel.

A single line patch fixing a regression that was introduced in 3.13 in the
reworking of the mxs touch screen and ADC drivers to be interrupt rather
than polling driven.  It resulted in a stray double reporting of the release
coordinate in the touch screen driver.  The bug lay in the adc side
of the driver which left the statemachine in the wrong state.

Add a maintainers entry for the Armada DRM driver.

Pull device mapper fixes from Mike Snitzer:
 "A few dm-cache fixes, an invalid ioctl handling fix for dm multipath,
  a couple immutable biovec fixups for dm mirror, and a few dm-thin
  fixes.

  There will likely be additional dm-thin metadata and data resize fixes
  to include in 3.14-rc6 next week.

  Note to stable-minded folks: Immutable biovecs were introduced in
  3.14, so the related fixups for dm mirror are not needed in stable@
  kernels"

Pull sound fixes from Takashi Iwai:
 "It's a bad habit to get a higher volume of fixes often lately, but
  things happen again.

  All commits found here are real bug fixes, and are mostly trivial.
  Most of changes in ASoC are the fixes for enum items due to the wrong
  API usages, in addition to a few DAPM mutex deadlock and other fixes.
  In HD-audio, only fixups for HP laptops.  Although diffstat shows
  much, the changes are simple: there are just so many different device
  entries there"
