Fix firmware loader uevent buffer NULL pointer dereference
commit 6f957724b94cb19f5c1c97efd01dd4df8ced323c upstream.
The firmware class uevent function accessed the "fw_priv->buf" buffer
without the proper locking and testing for NULL. This is an old bug
(looks like it goes back to 2012 and commit 1244691c73b2: "firmware
loader: introduce firmware_buf"), but for some reason it's triggering
only now in 4.2-rc1.
Shuah Khan is trying to bisect what it is that causes this to trigger
more easily, but in the meantime let's just fix the bug since others are
hitting it too (at least Ingo reports having seen it as well).

In needs_ilk_vtd_wa(), we pass in the GPU device but compared it against
the ids for the mobile GPU and the mobile host bridge. That latter is
impossible and so likely was just a typo for the desktop GPU device id
(which is also buggy).

rbd: use GFP_NOIO in rbd_obj_request_create()
commit 5a60e87603c4c533492c515b7f62578189b03c9c upstream.
rbd_obj_request_create() is called on the main I/O path, so we need to
use GFP_NOIO to make sure allocation doesn't blow back on us. Not all
callers need this, but I'm still hardcoding the flag inside rather than
making it a parameter because a) this is going to stable, and b) those
callers shouldn't really use rbd_obj_request_create() and will be fixed
in the future.
More memory allocation fixes will follow.

fixing infinite OPEN loop in 4.0 stateid recovery
commit e8d975e73e5fa05f983fbf2723120edcf68e0b38 upstream.
Problem: When an operation like WRITE receives a BAD_STATEID, even though
recovery code clears the RECLAIM_NOGRACE recovery flag before recovering
the open state, because of clearing delegation state for the associated
inode, nfs_inode_find_state_and_recover() gets called and it makes the
same state with RECLAIM_NOGRACE flag again. As a results, when we restart
looking over the open states, we end up in the infinite loop instead of
breaking out in the next test of state flags.
Solution: unset the RECLAIM_NOGRACE set because of
calling of nfs_inode_find_state_and_recover() after returning from calling
recover_open() function.

watchdog: omap: assert the counter being stopped before reprogramming
commit 530c11d432727c697629ad5f9d00ee8e2864d453 upstream.
The omap watchdog has the annoying behaviour that writes to most
registers don't have any effect when the watchdog is already running.
Quoting the AM335x reference manual:
To modify the timer counter value (the WDT_WCRR register),
prescaler ratio (the WDT_WCLR[4:2] PTV bit field), delay
configuration value (the WDT_WDLY[31:0] DLY_VALUE bit field), or
the load value (the WDT_WLDR[31:0] TIMER_LOAD bit field), the
watchdog timer must be disabled by using the start/stop sequence
(the WDT_WSPR register).
Currently the timer is stopped in the .probe callback but still there
are possibilities that yield to a situation where omap_wdt_start is
entered with the timer running (e.g. when /dev/watchdog is closed
without stopping and then reopened). In such a case programming the
timeout silently fails!
To circumvent this stop the timer before reprogramming.
Assuming one of the first things the watchdog user does is setting the
timeout explicitly nothing too bad should happen because this explicit
setting works fine.

USB: usbfs: allow URBs to be reaped after disconnection
commit 3f2cee73b650921b2e214bf487b2061a1c266504 upstream.
The usbfs API has a peculiar hole: Users are not allowed to reap their
URBs after the device has been disconnected. There doesn't seem to be
any good reason for this; it is an ad-hoc inconsistency.
The patch allows users to issue the USBDEVFS_REAPURB and
USBDEVFS_REAPURBNDELAY ioctls (together with their 32-bit counterparts
on 64-bit systems) even after the device is gone. If no URBs are
pending for a disconnected device then the ioctls will return -ENODEV
rather than -EAGAIN, because obviously no new URBs will ever be able
to complete.
The patch also adds a new capability flag for
USBDEVFS_GET_CAPABILITIES to indicate that the reap-after-disconnect
feature is supported.

mac80211: prevent possible crypto tx tailroom corruption
commit ab499db80fcf07c18e4053f91a619500f663e90e upstream.
There was a possible race between
ieee80211_reconfig() and
ieee80211_delayed_tailroom_dec(). This could
result in inability to transmit data if driver
crashed during roaming or rekeying and subsequent
skbs with insufficient tailroom appeared.
This race was probably never seen in the wild
because a device driver would have to crash AND
recover within 0.5s which is very unlikely.
I was able to prove this race exists after
changing the delay to 10s locally and crashing
ath10k via debugfs immediately after GTK
rekeying. In case of ath10k the counter went below
0. This was harmless but other drivers which
actually require tailroom (e.g. for WEP ICV or
MMIC) could end up with the counter at 0 instead
of >0 and introduce insufficient skb tailroom
failures because mac80211 would not resize skbs
appropriately anymore.

__bitmap_parselist: fix bug in empty string handling
commit 2528a8b8f457d7432552d0e2b6f0f4046bb702f4 upstream.
bitmap_parselist("", &mask, nmaskbits) will erroneously set bit zero in
the mask. The same bug is visible in cpumask_parselist() since it is
layered on top of the bitmask code, e.g. if you boot with "isolcpus=",
you will actually end up with cpu zero isolated.
The bug was introduced in commit 4b060420a596 ("bitmap, irq: add
smp_affinity_list interface to /proc/irq") when bitmap_parselist() was
generalized to support userspace as well as kernelspace.

mmc: card: Fixup request missing in mmc_blk_issue_rw_rq
commit 29535f7b797df35cc9b6b3bca635591cdd3dd2a8 upstream.
The current handler of MMC_BLK_CMD_ERR in mmc_blk_issue_rw_rq function
may cause new coming request permanent missing when the ongoing
request (previoulsy started) complete end.
The problem scenario is as follows:
(1) Request A is ongoing;
(2) Request B arrived, and finally mmc_blk_issue_rw_rq() is called;
(3) Request A encounters the MMC_BLK_CMD_ERR error;
(4) In the error handling of MMC_BLK_CMD_ERR, suppose mmc_blk_cmd_err()
end request A completed and return zero. Continue the error handling,
suppose mmc_blk_reset() reset device success;
(5) Continue the execution, while loop completed because variable ret
is zero now;
(6) Finally, mmc_blk_issue_rw_rq() return without processing request B.
The process related to the missing request may wait that IO request
complete forever, possibly crashing the application or hanging the system.
Fix this issue by starting new request when reset success.

iser-target: release stale iser connections
commit 2f1b6b7d9a815f341b18dfd26a363f37d4d3c96a upstream.
When receiving a new iser connect request we serialize
the pending requests by adding the newly created iser connection
to the np accept list and let the login thread process the connect
request one by one (np_accept_wait).
In case we received a disconnect request before the iser_conn
has begun processing (still linked in np_accept_list) we should
detach it from the list and clean it up and not have the login
thread process a stale connection. We do it only when the connection
state is not already terminating (initiator driven disconnect) as
this might lead us to access np_accept_mutex after the np was released
in live shutdown scenarios.

iscsi-target: Convert iscsi_thread_set usage to kthread.h
commit 88dcd2dab5c23b1c9cfc396246d8f476c872f0ca upstream.
This patch converts iscsi-target code to use modern kthread.h API
callers for creating RX/TX threads for each new iscsi_conn descriptor,
and releasing associated RX/TX threads during connection shutdown.
This is done using iscsit_start_kthreads() -> kthread_run() to start
new kthreads from within iscsi_post_login_handler(), and invoking
kthread_stop() from existing iscsit_close_connection() code.
Also, convert iscsit_logout_post_handler_closesession() code to use
cmpxchg when determing when iscsit_cause_connection_reinstatement()
needs to sleep waiting for completion.

Btrfs: use kmem_cache_free when freeing entry in inode cache
commit c3f4a1685bb87e59c886ee68f7967eae07d4dffa upstream.
The free space entries are allocated using kmem_cache_zalloc(),
through __btrfs_add_free_space(), therefore we should use
kmem_cache_free() and not kfree() to avoid any confusion and
any potential problem. Looking at the kfree() definition at
mm/slab.c it has the following comment:
/*
* (...)
*
* Don't free memory not originally allocated by kmalloc()
* or you will run into trouble.
*/
So better be safe and use kmem_cache_free().

hwmon: (mcp3021) Fix broken output scaling
commit 347d7e45bd09ce09cbc30d5cea9de377eb22f55c upstream.
The mcp3021 scaling code is dividing the VDD (full-scale) value in
millivolts by the A2D resolution to obtain the scaling factor. When VDD
is 3300mV (the standard value) and the resolution is 12-bit (4096
divisions), the result is a scale factor of 3300/4096, which is always
one. Effectively, the raw A2D reading is always being returned because
no scaling is applied.
This patch fixes the issue and simplifies the register-to-volts
calculation, removing the unneeded "output_scale" struct member.

This patch fixes a bug in the XOR driver where the cleanup function can be

result in data errors).
The cleanup function will free descriptors based on the ownership bit in

tracing: Have branch tracer use recursive field of task struct
commit 6224beb12e190ff11f3c7d4bf50cb2922878f600 upstream.
Fengguang Wu's tests triggered a bug in the branch tracer's start up
test when CONFIG_DEBUG_PREEMPT set. This was because that config
adds some debug logic in the per cpu field, which calls back into
the branch tracer.
The branch tracer has its own recursive checks, but uses a per cpu
variable to implement it. If retrieving the per cpu variable calls
back into the branch tracer, you can see how things will break.
Instead of using a per cpu variable, use the trace_recursion field
of the current task struct. Simply set a bit when entering the
branch tracing and clear it when leaving. If the bit is set on
entry, just don't do the tracing.
There's also the case with lockdep, as the local_irq_save() called
before the recursion can also trigger code that can call back into
the function. Changing that to a raw_local_irq_save() will protect
that as well.
This prevents the recursion and the inevitable crash that follows.

tracing/filter: Do not allow infix to exceed end of string
commit 6b88f44e161b9ee2a803e5b2b1fbcf4e20e8b980 upstream.
While debugging a WARN_ON() for filtering, I found that it is possible
for the filter string to be referenced after its end. With the filter:
# echo '>' > /sys/kernel/debug/events/ext4/ext4_truncate_exit/filter
The filter_parse() function can call infix_get_op() which calls
infix_advance() that updates the infix filter pointers for the cnt
and tail without checking if the filter is already at the end, which
will put the cnt to zero and the tail beyond the end. The loop then calls
infix_next() that has
ps->infix.cnt--;
return ps->infix.string[ps->infix.tail++];
The cnt will now be below zero, and the tail that is returned is
already passed the end of the filter string. So far the allocation
of the filter string usually has some buffer that is zeroed out, but
if the filter string is of the exact size of the allocated buffer
there's no guarantee that the charater after the nul terminating
character will be zero.
Luckily, only root can write to the filter.

tracing/filter: Do not WARN on operand count going below zero
commit b4875bbe7e68f139bd3383828ae8e994a0df6d28 upstream.
When testing the fix for the trace filter, I could not come up with
a scenario where the operand count goes below zero, so I added a
WARN_ON_ONCE(cnt < 0) to the logic. But there is legitimate case
that it can happen (although the filter would be wrong).
# echo '>' > /sys/kernel/debug/events/ext4/ext4_truncate_exit/filter
That is, a single operation without any operands will hit the path
where the WARN_ON_ONCE() can trigger. Although this is harmless,
and the filter is reported as a error. But instead of spitting out
a warning to the kernel dmesg, just fail nicely and report it via
the proper channels.

xfs: fix remote symlinks on V5/CRC filesystems
commit 2ac56d3d4bd625450a54d4c3f9292d58f6b88232 upstream.
If we create a CRC filesystem, mount it, and create a symlink with
a path long enough that it can't live in the inode, we get a very
strange result upon remount:
# ls -l mnt
total 4
lrwxrwxrwx. 1 root root 929 Jun 15 16:58 link -> XSLM
XSLM is the V5 symlink block header magic (which happens to be
followed by a NUL, so the string looks terminated).
xfs_readlink_bmap() advanced cur_chunk by the size of the header
for CRC filesystems, but never actually used that pointer; it
kept reading from bp->b_addr, which is the start of the block,
rather than the start of the symlink data after the header.
Looks like this problem goes back to v3.10.
Fixing this gets us reading the proper link target, again.

usb: xhci: Bugfix for NULL pointer deference in xhci_endpoint_init() function
commit 3496810663922617d4b706ef2780c279252ddd6a upstream.
virt_dev->num_cached_rings counts on freed ring and is not updated
correctly. In xhci_free_or_cache_endpoint_ring() function, the free ring
is added into cache and then num_rings_cache is incremented as below:
virt_dev->ring_cache[rings_cached] =
virt_dev->eps[ep_index].ring;
virt_dev->num_rings_cached++;
here, free ring pointer is added to a current index and then
index is incremented.
So current index always points to empty location in the ring cache.
For getting available free ring, current index should be decremented
first and then corresponding ring buffer value should be taken from ring
cache.
But In function xhci_endpoint_init(), the num_rings_cached index is
accessed before decrement.
virt_dev->eps[ep_index].new_ring =
virt_dev->ring_cache[virt_dev->num_rings_cached];
virt_dev->ring_cache[virt_dev->num_rings_cached] = NULL;
virt_dev->num_rings_cached--;
This is bug in manipulating the index of ring cache.
And it should be as below:
virt_dev->num_rings_cached--;
virt_dev->eps[ep_index].new_ring =
virt_dev->ring_cache[virt_dev->num_rings_cached];
virt_dev->ring_cache[virt_dev->num_rings_cached] = NULL;

usb: dwc3: Reset the transfer resource index on SET_INTERFACE
commit aebda618718157a69c0dc0adb978d69bc2b8723c upstream.
This fixes an issue introduced in commit b23c843992b6 (usb: dwc3:
gadget: fix DEPSTARTCFG for non-EP0 EPs) that made sure we would
only use DEPSTARTCFG once per SetConfig.
The trick is that we should use one DEPSTARTCFG per SetConfig *OR*
SetInterface. SetInterface was completely missed from the original
patch.
This problem became aparent after commit 76e838c9f776 (usb: dwc3:
gadget: return error if command sent to DEPCMD register fails)
added checking of the return status of device endpoint commands.
'Set Endpoint Transfer Resource' command was caught failing
occasionally. This is because the Transfer Resource
Index was not getting reset during a SET_INTERFACE request.
Finally, to fix the issue, was we have to do is make sure that

libata: increase the timeout when setting transfer mode
commit d531be2ca2f27cca5f041b6a140504999144a617 upstream.
I have a ST4000DM000 disk. If Linux is booted while the disk is spun down,
the command that sets transfer mode causes the disk to spin up. The
spin-up takes longer than the default 5s timeout, so the command fails and
timeout is reported.
Fix this by increasing the timeout to 15s, which is enough for the disk to
spin up.

i2c: at91: fix a race condition when using the DMA controller
commit 93563a6a71bb69dd324fc7354c60fb05f84aae6b upstream.
For TX transactions, the TXCOMP bit in the Status Register is cleared
when the first data is written into the Transmit Holding Register.
In the lines from at91_do_twi_transfer():
at91_twi_write_data_dma(dev);
at91_twi_write(dev, AT91_TWI_IER, AT91_TWI_TXCOMP);
the TXCOMP interrupt may be enabled before the DMA controller has
actually started to write into the THR. In such a case, the TXCOMP bit
is still set into the Status Register so the interrupt is triggered
immediately. The driver understands that a transaction completion has
occurred but this transaction hasn't started yet. Hence the TXCOMP
interrupt is no longer enabled by at91_do_twi_transfer() but instead
by at91_twi_write_data_dma_callback().
Also, the TXCOMP bit in the Status Register in not a clear on read flag
but a snapshot of the transmission state at the time the Status
Register is read.
When a NACK error is dectected by the I2C controller, the TXCOMP, NACK
and TXRDY bits are set together to 1 in the SR. If enabled, the TXCOMP
interrupt is triggered at the same time. Also setting the TXRDY to 1
triggers the DMA controller to write the next data into the THR. Such
a write resets the TXCOMP bit to 0 in the SR. So depending on when the
interrupt handler reads the SR, it may fail to detect the NACK error
if it relies on the TXCOMP bit. The NACK bit and its interrupt should
be used instead.
For RX transactions, the TXCOMP bit in the Status Register is cleared
when the START bit is set into the Control Register. However to unify
the management of the TXCOMP bit when the DMA controller is used, the
TXCOMP interrupt is now enabled by the DMA callbacks for both TX and
RX transfers.

jbd2: fix ocfs2 corrupt when updating journal superblock fails
commit 6f6a6fda294506dfe0e3e0a253bb2d2923f28f0a upstream.
If updating journal superblock fails after journal data has been
flushed, the error is omitted and this will mislead the caller as a
normal case. In ocfs2, the checkpoint will be treated successfully
and the other node can get the lock to update. Since the sb_start is
still pointing to the old log block, it will rewrite the journal data
during journal recovery by the other node. Thus the new updates will
be overwritten and ocfs2 corrupts. So in above case we have to return
the error, and ocfs2_commit_cache will take care of the error and
prevent the other node to do update first. And only after recovering
journal it can do the new updates.

ext4: correctly migrate a file with a hole at the beginning
commit 8974fec7d72e3e02752fe0f27b4c3719c78d9a15 upstream.
Currently ext4_ind_migrate() doesn't correctly handle a file which
contains a hole at the beginning of the file. This caused the migration
to be done incorrectly, and then if there is a subsequent following
delayed allocation write to the "hole", this would reclaim the same data
blocks again and results in fs corruption.
# assmuing 4k block size ext4, with delalloc enabled
# skip the first block and write to the second block
xfs_io -fc "pwrite 4k 4k" -c "fsync" /mnt/ext4/testfile
# converting to indirect-mapped file, which would move the data blocks
# to the beginning of the file, but extent status cache still marks
# that region as a hole
chattr -e /mnt/ext4/testfile
# delayed allocation writes to the "hole", reclaim the same data block
# again, results in i_blocks corruption

ext4: be more strict when migrating to non-extent based file
commit d6f123a9297496ad0b6335fe881504c4b5b2a5e5 upstream.
Currently the check in ext4_ind_migrate() is not enough before doing the
real conversion:
a) delayed allocated extents could bypass the check on eh->eh_entries
and eh->eh_depth
This can be demonstrated by this script
xfs_io -fc "pwrite 0 4k" -c "pwrite 8k 4k" /mnt/ext4/testfile
chattr -e /mnt/ext4/testfile
where testfile has two extents but still be converted to non-extent
based file format.
b) only extent length is checked but not the offset, which would result
in data lose (delalloc) or fs corruption (nodelalloc), because
non-extent based file only supports at most (12 + 2^10 + 2^20 + 2^30)
blocks
This can be demostrated by
xfs_io -fc "pwrite 5T 4k" /mnt/ext4/testfile
chattr -e /mnt/ext4/testfile
sync
If delalloc is enabled, dmesg prints
EXT4-fs warning (device dm-4): ext4_block_to_path:105: block 1342177280 > max in inode 53
EXT4-fs (dm-4): Delayed block allocation failed for inode 53 at logical offset 1342177280 with max blocks 1 with error 5
EXT4-fs (dm-4): This should not happen!! Data will be lost
If delalloc is disabled, e2fsck -nf shows corruption
Inode 53, i_size is 5497558142976, should be 4096. Fix? no
Fix the two issues by
a) forcing all delayed allocation blocks to be allocated before checking
eh->eh_depth and eh->eh_entries
b) limiting the last logical block of the extent is within direct map

ext4: fix reservation release on invalidatepage for delalloc fs
commit 9705acd63b125dee8b15c705216d7186daea4625 upstream.
On delalloc enabled file system on invalidatepage operation
in ext4_da_page_release_reservation() we want to clear the delayed
buffer and remove the extent covering the delayed buffer from the extent
status tree.
However currently there is a bug where on the systems with page size >
block size we will always remove extents from the start of the page
regardless where the actual delayed buffers are positioned in the page.
This leads to the errors like this:
EXT4-fs warning (device loop0): ext4_da_release_space:1225:
ext4_da_release_space: ino 13, to_free 1 with only 0 reserved data
blocks
This however can cause data loss on writeback time if the file system is
in ENOSPC condition because we're releasing reservation for someones
else delayed buffer.
Fix this by only removing extents that corresponds to the part of the
page we want to invalidate.
This problem is reproducible by the following fio receipt (however I was
only able to reproduce it with fio-2.1 or older.

ext4: don't retry file block mapping on bigalloc fs with non-extent file
commit 292db1bc6c105d86111e858859456bcb11f90f91 upstream.
ext4 isn't willing to map clusters to a non-extent file. Don't signal
this with an out of space error, since the FS will retry the
allocation (which didn't fail) forever. Instead, return EUCLEAN so
that the operation will fail immediately all the way back to userspace.
(The fix is either to run e2fsck -E bmap2extent, or to chattr +e the file.)

ext4: call sync_blockdev() before invalidate_bdev() in put_super()
commit 89d96a6f8e6491f24fc8f99fd6ae66820e85c6c1 upstream.
Normally all of the buffers will have been forced out to disk before
we call invalidate_bdev(), but there will be some cases, where a file
system operation was aborted due to an ext4_error(), where there may
still be some dirty buffers in the buffer cache for the device. So
try to force them out to memory before calling invalidate_bdev().
This fixes a warning triggered by generic/081:

ext4: fix race between truncate and __ext4_journalled_writepage()
commit bdf96838aea6a265f2ae6cbcfb12a778c84a0b8e upstream.
The commit cf108bca465d: "ext4: Invert the locking order of page_lock
and transaction start" caused __ext4_journalled_writepage() to drop
the page lock before the page was written back, as part of changing
the locking order to jbd2_journal_start -> page_lock. However, this
introduced a potential race if there was a truncate racing with the
data=journalled writeback mode.
Fix this by grabbing the page lock after starting the journal handle,
and then checking to see if page had gotten truncated out from under
us.
This fixes a number of different warnings or BUG_ON's when running
xfstests generic/086 in data=journalled mode, including:
jbd2_journal_dirty_metadata: vdc-8: bad jh for block 115643: transaction (ee3fe7

arm64: vdso: work-around broken ELF toolchains in Makefile
commit 6f1a6ae87c0c60d7c462ef8fd071f291aa7a9abb upstream.
When building the kernel with a bare-metal (ELF) toolchain, the -shared
option may not be passed down to collect2, resulting in silent corruption
of the vDSO image (in particular, the DYNAMIC section is omitted).
The effect of this corruption is that the dynamic linker fails to find
the vDSO symbols and libc is instead used for the syscalls that we
intended to optimise (e.g. gettimeofday). Functionally, there is no
issue as the sigreturn trampoline is still intact and located by the
kernel.
This patch fixes the problem by explicitly passing -shared to the linker
when building the vDSO.

arm64: mm: Fix freeing of the wrong memmap entries with !SPARSEMEM_VMEMMAP
commit b9bcc919931611498e856eae9bf66337330d04cc upstream.
The memmap freeing code in free_unused_memmap() computes the end of
each memblock by adding the memblock size onto the base. However,
if SPARSEMEM is enabled then the value (start) used for the base
may already have been rounded downwards to work out which memmap
entries to free after the previous memblock.
This may cause memmap entries that are in use to get freed.
In general, you're not likely to hit this problem unless there
are at least 2 memblocks and one of them is not aligned to a
sparsemem section boundary. Note that carve-outs can increase
the number of memblocks by splitting the regions listed in the
device tree.
This problem doesn't occur with SPARSEMEM_VMEMMAP, because the
vmemmap code deals with freeing the unused regions of the memmap
instead of requiring the arch code to do it.
This patch gets the memblock base out of the memblock directly when
computing the block end address to ensure the correct value is used.

arm64: Do not attempt to use init_mm in reset_context()
commit 565630d503ef24e44c252bed55571b3a0d68455f upstream.
After secondary CPU boot or hotplug, the active_mm of the idle thread is
&init_mm. The init_mm.pgd (swapper_pg_dir) is only meant for TTBR1_EL1
and must not be set in TTBR0_EL1. Since when active_mm == &init_mm the
TTBR0_EL1 is already set to the reserved value, there is no need to
perform any context reset.

ARC: add compiler barrier to LLSC based cmpxchg
commit d57f727264f1425a94689bafc7e99e502cb135b5 upstream.
When auditing cmpxchg call sites, Chuck noted that gcc was optimizing
away some of the desired LDs.
| do {
| new = old = *ipi_data_ptr;
| new |= 1U << msg;
| } while (cmpxchg(ipi_data_ptr, old, new) != old);
was generating to below
| 8015cef8: ld r2,[r4,0] <-- First LD
| 8015cefc: bset r1,r2,r1
|
| 8015cf00: llock r3,[r4] <-- atomic op
| 8015cf04: brne r3,r2,8015cf10
| 8015cf08: scond r1,[r4]
| 8015cf0c: bnz 8015cf00
|
| 8015cf10: brne r3,r2,8015cf00 <-- Branch doesn't go to orig LD
Although this was fixed by adding a ACCESS_ONCE in this call site, it
seems safer (for now at least) to add compiler barrier to LLSC based
cmpxchg

ALSA: hda - Fix the dock headphone output on Fujitsu Lifebook E780
commit 4df3fd1700abbb53bd874143dfd1f9ac9e7cbf4b upstream.
Fujitsu Lifebook E780 sets the sequence number 0x0f to only only of
the two headphones, thus the driver tries to assign another as the
line-out, and this results in the inconsistent mapping between the
created jack ctl and the actual I/O. Due to this, PulseAudio doesn't
handle it properly and gets the silent output.
The fix is to ignore the non-HP sequencer checks.

ALSA: hda - Add headset support to Acer Aspire V5
commit 7819717b11346b8a5420b223b46600e394049c66 upstream.
Acer Aspire V5 with ALC282 codec needs the similar quirk like Dell
laptops to support the headset mic. The headset mic pin is 0x19 and
it's not exposed by BIOS, thus we need to fix the pincfg as well.

Disable write buffering on Toshiba ToPIC95
commit 2fb22a8042fe96b4220843f79241c116d90922c4 upstream.
Disable write buffering on the Toshiba ToPIC95 if it is enabled by
somebody (it is not supposed to be a power-on default according to
the datasheet). On the ToPIC95, practically no 32-bit Cardbus card
will work under heavy load without locking up the whole system if
this is left enabled. I tried about a dozen. It does not affect
16-bit cards. This is similar to the O2 bugs in early controller
revisions it seems.

ipr: Increase default adapter init stage change timeout
commit 45c44b5ff9caa743ed9c2bfd44307c536c9caf1e upstream.
Increase the default init stage change timeout from 15 seconds to 30 seconds.
This resolves issues we have seen with some adapters not transitioning
to the first init stage within 15 seconds, which results in adapter
initialization failures.
