Input: elants_i2c - append hw_version to FW file
Currently the elants_i2c driver simply requests a static filename
/lib/firmware/elants_i2c.bin when it gets firmware updates. This is a
problem if you have two Elan touchscreens using the same driver. If both
touchscreens have different firmwares, you would need to move the files
around in your filesystem when you're updating them so that they don't get
updated with the other's FW. If you have a read-only filesystem then this
is impossible, even.
This patch changes the elants_i2c driver to automatically append the
four-hex-digit hw_version of the device onto the name of the FW file it's
requesting for update. Since different touchscreens should have a
different hw_version's this means the user needs to append the hw version
of the touchscreen he or she intends to update onto the end of the firmware
filename and then the driver will do the rest.
The firmware filenames it looks for now are of the form:
elants_i2c_${HW_VERSION}.bin
eg:
elants_i2c_2a44.bin

Pull ftrace fixes from Steven Rostedt:
"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"

When taking a CPU down for suspend and resume, a tracepoint may be called

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

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.

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.
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.

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).

IRQCHIP: mips-gic: Avoid rerouting timer IRQs for smp-cmp
Commit e9de688dac65 ("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.

We might be able to filter out the invalid modes in mode_valid

So, instead, this patch adds the bpp module option to specify the

depending on its value.
The default value is set to 24 so that the existing stuff keeps
working. If you need a new 32bpp feature, specify cirrus.bpp=32
