4e02370f64 During testing Sedat Dilek hit a "suspicious RCU usage" splat that pointed
out a real bug. During suspend and resume the tlb_flush tracepoint is
 called when the CPU is going offline. As the CPU has been noted as offline,
 RCU is ignoring that CPU, which means that it can not use RCU protected
 locks. When tracepoints are activated, they require RCU locking, and
 if RCU is ignoring a CPU that runs a tracepoint, there is a chance that
 the tracepoint could cause corruption.
 
 The solution was to change the tracepoint into a TRACE_EVENT_CONDITION()
 which allows us to check a condition to determine if the tracepoint
 should be called or not. If the condition is not met, the rcu protected
 code will not be executed. By adding the condition
 "cpu_online(smp_processor_id())", this will prevent the RCU protected
 code from being executed if the CPU is marked offline.
 
 After adding this, another bug was discovered. As RCU checks rcu callers,
 if a rcu call is not done, there is no check (obviously). We found that
 tracepoints could be added in RCU ignored locations and not have lockdep
 complain until the tracepoint is activated. This missed places where
 tracepoints were added in places they should not have been. To fix this,
 code was added in 3.18 that if lockdep is enabled, any tracepoint will
 still call the rcu checks even if the tracepoint is not enabled. The bug
 here, is that the check does not take the CONDITION into account. As the
 condition may prevent tracepoints from being activated in RCU ignored
 areas (as the one patch does), we get false positives when we enable
 lockdep and hit a tracepoint that the condition prevents it from being
 called in a RCU ignored location. The fix for this is to add the
 CONDITION to the rcu checks, even if the tracepoint is not enabled.

6c8465a82a x86/tlb/trace: Do not trace on CPU that is offline
When taking a CPU down for suspend and resume, a tracepoint may be called
when the CPU has been designated offline. As tracepoints require RCU for
protection, they must not be called if the current CPU is offline.

Unfortunately, trace_tlb_flush() is called in this scenario as was noted
by LOCKDEP:

By converting the tlb_flush tracepoint to a TRACE_EVENT_CONDITION where the
condition is cpu_online(smp_processor_id()), we can avoid calling RCU protected
code when the CPU is offline.

a05d59a567 tracing: Add condition check to RCU lockdep checks
The trace_tlb_flush() tracepoint can be called when a CPU is going offline.
When a CPU is offline, RCU is no longer watching that CPU and since the
tracepoint is protected by RCU, it must not be called. To prevent the
tlb_flush tracepoint from being called when the CPU is offline, it was
converted to a TRACE_EVENT_CONDITION where the condition checks if the
CPU is online before calling the tracepoint.

Unfortunately, this was not enough to stop lockdep from complaining about
it. Even though the RCU protected code of the tracepoint will never be
called, the condition is hidden within the tracepoint, and even though the
condition prevents RCU code from being called, the lockdep checks are
outside the tracepoint (this is to test tracepoints even when they are not
enabled).

Even though tracepoints should be checked to be RCU safe when they are not
enabled, the condition should still be considered when checking RCU.

Hopefully the final pull request for 3.19: this ended up with a
 slightly higher volume than wished, but I put them all as they are

 Most of commits are from ASoC, and have been stewed for a while in
 linux-next.  The only change in the common code is the regression
 fixes for ASoC AC97 stuff wrt device registrations.  The rest are
 device-specific, mostly small fixes in various ASoC drivers and

43c6116573 Revert "IB/core: Add support for extended query device caps"
While commit 7e36ef8205 ("IB/core: Temporarily disable
ex_query_device uverb") is correct as it makes the extended
QUERY_DEVICE uverb (which came as part of commit 5a77abf9a9
("IB/core: Add support for extended query device caps") and commit
860f10a799 ("IB/core: Add flags for on demand paging support")) not
available to userspace, it doesn't address the initial issue regarding
ib_copy_to_udata() [1][2].

Additionally, further discussions around this new uverb seems to
conclude it would require a different data structure than the one
currently described in <rdma/ib_user_verbs.h> [3].

Both of these issues require a revert of the changes, so this patch
partially reverts commit 8cdd312cfe ("IB/mlx5: Implement the ODP
capability query verb") and commit 860f10a799 ("IB/core: Add flags
for on demand paging support") and fully reverts commit 5a77abf9a9
("IB/core: Add support for extended query device caps").

7b02190c27 mm/debug_pagealloc: fix build failure on ppc and some other archs
Kim Phillips reported following build failure.

  LD      init/built-in.o
  mm/built-in.o: In function `free_pages_prepare':
  mm/page_alloc.c:770: undefined reference to `.kernel_map_pages'
  mm/built-in.o: In function `prep_new_page':

  mm/built-in.o: In function `map_pages':
  mm/compaction.c:61: undefined reference to `.kernel_map_pages'
  make: *** [vmlinux] Error 1

Reason for this problem is that commit 031bc5743f
("mm/debug-pagealloc: make debug-pagealloc boottime configurable")
forgot to remove the old declaration of kernel_map_pages() for some
architectures.  This patch removes them to fix build failure.

7ef3ff2fea nilfs2: fix deadlock of segment constructor over I_SYNC flag
Nilfs2 eventually hangs in a stress test with fsstress program.  This
issue was caused by the following deadlock over I_SYNC flag between
nilfs_segctor_thread() and writeback_sb_inodes():

  nilfs_segctor_thread()
    nilfs_segctor_thread_construct()
      nilfs_segctor_unlock()
        nilfs_dispose_list()
          iput()
            iput_final()
              evict()
                inode_wait_for_writeback()  * wait for I_SYNC flag

  writeback_sb_inodes()
     * set I_SYNC flag on inode->i_state
    __writeback_single_inode()
      do_writepages()
        nilfs_writepages()
          nilfs_construct_dsync_segment()
            nilfs_segctor_sync()
               * wait for completion of segment constructor
    inode_sync_complete()
       * clear I_SYNC flag after __writeback_single_inode() completed

writeback_sb_inodes() calls do_writepages() for dirty inodes after
setting I_SYNC flag on inode->i_state.  do_writepages() in turn calls
nilfs_writepages(), which can run segment constructor and wait for its
completion.  On the other hand, segment constructor calls iput(), which
can call evict() and wait for the I_SYNC flag on
inode_wait_for_writeback().

Since segment constructor doesn't know when I_SYNC will be set, it
cannot know whether iput() will block or not unless inode->i_nlink has a
non-zero count.  We can prevent evict() from being called in iput() by
implementing sop->drop_inode(), but it's not preferable to leave inodes
with i_nlink == 0 for long periods because it even defers file
truncation and inode deallocation.  So, this instead resolves the
deadlock by calling iput() asynchronously with a workqueue for inodes
with i_nlink == 0.

f5e03a4989 memcg, shmem: fix shmem migration to use lrucare
It has been reported that 965GM might trigger

  VM_BUG_ON_PAGE(!lrucare && PageLRU(oldpage), oldpage)

in mem_cgroup_migrate when shmem wants to replace a swap cache page
because of shmem_should_replace_page (the page is allocated from an
inappropriate zone).  shmem_replace_page expects that the oldpage is not
on LRU list and calls mem_cgroup_migrate without lrucare.  This is
obviously incorrect because swapcache pages might be on the LRU list
(e.g. swapin readahead page).

Fix this by enabling lrucare for the migration in shmem_replace_page.
Also clarify that lrucare should be used even if one of the pages might
be on LRU list.

The BUG_ON will trigger only when CONFIG_DEBUG_VM is enabled but even
without that the migration code might leave the old page on an
inappropriate memcg' LRU which is not that critical because the page
would get removed with its last reference but it is still confusing.

23aaed6659 mm: pagewalk: call pte_hole() for VM_PFNMAP during walk_page_range
walk_page_range() silently skips vma having VM_PFNMAP set, which leads
to undesirable behaviour at client end (who called walk_page_range).
Userspace applications get the wrong data, so the effect is like just
confusing users (if the applications just display the data) or sometimes
killing the processes (if the applications do something with
misunderstanding virtual addresses due to the wrong data.)

For example for pagemap_read, when no callbacks are called against
VM_PFNMAP vma, pagemap_read may prepare pagemap data for next virtual
address range at wrong index.

Eventually userspace may get wrong pagemap data for a task.
Corresponding to a VM_PFNMAP marked vma region, kernel may report
mappings from subsequent vma regions.  User space in turn may account
more pages (than really are) to the task.

In my case I was using procmem, procrack (Android utility) which uses
pagemap interface to account RSS pages of a task.  Due to this bug it
was giving a wrong picture for vmas (with VM_PFNMAP set).

14365ea2b8 SCSI fixes on 20150205
This patch set is fixing two serious problems which have turned up late in the
 release cycle.  The first fixes a problem with 4k sector disks where the
 transfer length (amount of data sent to the disk) was getting increased every
 time the disk was revalidated leading to potential for overflows.  The other
 is a regression oops fix for some of our last merge window code.

e7394c776f ACPI power management fix for final 3.19
This is a revert of an ACPI Low-power Subsystem (LPSS) driver change
 that was supposed to improve power management of the LPSS DMA controller,
 but introduced more serious problems.
 
 Since fixing them turns out to be non-trivial, it is better to revert
 the commit in question at this point and try to fix the original issue
 differently in the next cycle.

1b6af71a8f IRQCHIP: mips-gic: Avoid rerouting timer IRQs for smp-cmp
Commit e9de688dac ("irqchip: mips-gic: Support local interrupts")
changed the GIC irqchip driver so that all local interrupts were routed
to the same CPU pin used for external interrupts. Unfortunately this
causes a regression when smp-cmp is used. The CPUs are started by the
bootloader and put in a timer based waiting poll loop, but when their
timer interrupts are rerouted to a different IRQ pin which is not
unmasked they never wake up.

Since smp-cmp support is deprecated and everybody who was using it
should be switching to smp-cps which brings up the secondary CPUs
without bootloader assistance, I've gone for the simple fix which can be
easily removed once smp-cmp is removed, rather than a fully generic fix.

In __gic_init() the local GIC_VPE_TIMER_MAP register is read to find the
boot-time routing of the local timer interrupt, and a chained handler is
added to that CPU pin as well as the normal one.
