commit b38f09ccc3fd453180e96273bf3f34083c30809a upstream.
Sony VAIO t-series machines are not capable of switching usb2 ports over
from Intel EHCI to xHCI controller. If tried the USB2 port will be left
unconnected and unusable.
This patch should be backported to stable kernels as old as 3.12,
that contain the commit 26b76798e0507429506b93cd49f8c4cfdab06896

commit c03890ff5e24a4bf59059f2d179f427559b7330a upstream.
A recent patch that purported to fix firmware download on big-endian
machines failed to add the corresponding sparse annotation to the
i2c-header. This was reported by the kbuild test robot.
Adding the appropriate annotation revealed another endianess bug related
to the i2c-header Size-field in a code path that is exercised when the
firmware is actually being downloaded (and not just verified and left
untouched unless older than the firmware at hand).
This patch adds the required sparse annotation to the i2c-header and
makes sure that the Size-field is sent in little-endian byte order
during firmware download also on big-endian machines.
Note that this patch is only compile-tested, but that there is no
functional change for little-endian systems.

The conversion to a fixup table for Replacer model with ALC260 in

NID 0x1a should have been used instead of NID 0x20, which is the

This function is largely a duplicate of paste_selection() in
drivers/tty/vt/selection.c, but with its own selection state. The
speakup selection mechanism should really be merged with vt.
For now, apply the changes from 'TTY: vt, fix paste_selection ldisc
handling', 'tty: Make ldisc input flow control concurrency-friendly',
and 'tty: Fix unsafe vt paste_selection()'.

commit d7500135802ca55b3f4e01a16544e8b34082f8c3 upstream.
Input is handled in softirq context, but when pasting we may
need to sleep. speakup_paste_selection() currently tries to
bodge this by busy-waiting if in_atomic(), but that doesn't
help because the ldisc may also sleep.
For bonus breakage, speakup_paste_selection() changes the
state of current, even though it's not running in process
context.
Move it into a work item and make sure to cancel it on exit.

commit 2ac295a544dcae9299cba13ce250419117ae7fd1 upstream.
Commit 8313b8e57f55b15e5b7f7fc5d1630bbf686a9a97
md: fix problem when adding device to read-only array with bitmap.
added a called to md_reap_sync_thread() which cause a reshape thread
to be interrupted (in particular, it could cause md_thread() to never even
call md_do_sync()).
However it didn't set MD_RECOVERY_INTR so ->finish_reshape() would not
know that the reshape didn't complete.
This only happens when mddev->ro is set and normally reshape threads
don't run in that situation. But raid5 and raid10 can start a reshape
thread during "run" is the array is in the middle of a reshape.
They do this even if ->ro is set.
So it is best to set MD_RECOVERY_INTR before abortingg the
sync thread, just in case.
Though it rare for this to trigger a problem it can cause data corruption
because the reshape isn't finished properly.
So it is suitable for any stable which the offending commit was applied to.
(3.2 or later)

commit 3991b31ea072b070081ca3bfa860a077eda67de5 upstream.
If mddev->ro is set, md_to_sync will (correctly) abort.
However in that case MD_RECOVERY_INTR isn't set.
If a RESHAPE had been requested, then ->finish_reshape() will be
called and it will think the reshape was successful even though
nothing happened.
Normally a resync will not be requested if ->ro is set, but if an
array is stopped while a reshape is on-going, then when the array is
started, the reshape will be restarted. If the array is also set
read-only at this point, the reshape will instantly appear to success,
resulting in data corruption.
Consequently, this patch is suitable for any -stable kernel.

commit 9aab8bff7aa3bee567213ad3c1fdfb217bb980a2 upstream.
We only want to modifiy a single field in the userspace view of the
execbuffer command buffer, so explicitly change that rather than copy
everything back again.
This serves two purposes:
1. The single fields are much cheaper to copy (constant size so the
copy uses special case code) and much smaller than the whole array.
2. We modify the array for internal use that need to be masked from
the user.
Note: We need this backported since without it the next bugfix will
blow up when userspace recycles batchbuffers and relocations.

commit 0f397f2c90ce68821ee864c2c53baafe78de765d upstream.
Throttled task is still on rq, and it may be moved to other cpu
if user is playing with sched_setaffinity(). Therefore, unlocked
task_rq() access makes the race.
Juri Lelli reports he got this race when dl_bandwidth_enabled()
was not set.
Other thing, pointed by Peter Zijlstra:
"Now I suppose the problem can still actually happen when
you change the root domain and trigger a effective affinity
change that way".
To fix that we do the same as made in __task_rq_lock(). We do not
use __task_rq_lock() itself, because it has a useful lockdep check,
which is not correct in case of dl_task_timer(). We do not need
pi_lock locked here. This case is an exception (PeterZ):
"The only reason we don't strictly need ->pi_lock now is because
we're guaranteed to have p->state == TASK_RUNNING here and are
thus free of ttwu races".

commit b0827819b0da4acfbc1df1e05edcf50efd07cbd1 upstream.
Michael Kerrisk noticed that creating SCHED_DEADLINE reservations
with certain parameters (e.g, a runtime of something near 2^64 ns)
can cause a system freeze for some amount of time.
The problem is that in the interface we have
u64 sched_runtime;
while internally we need to have a signed runtime (to cope with
budget overruns)
s64 runtime;
At the time we setup a new dl_entity we copy the first value in
the second. The cast turns out with negative values when
sched_runtime is too big, and this causes the scheduler to go crazy
right from the start.
Moreover, considering how we deal with deadlines wraparound
(s64)(a - b) < 0
we also have to restrict acceptable values for sched_{deadline,period}.
This patch fixes the thing checking that user parameters are always
below 2^63 ns (still large enough for everyone).
It also rewrites other conditions that we check, since in
__checkparam_dl we don't have to deal with deadline wraparounds
and what we have now erroneously fails when the difference between
values is too big.

The way we read POSIX one should only call sched_getparam() when

Given that we currently return sched_param::sched_priority=0 for all
others, extend the same behaviour to SCHED_DEADLINE.

commit 143cf23df25b7082cd706c3c53188e741e7881c3 upstream.
The documented[1] behavior of sched_attr() in the proposed man page text is:
sched_attr::size must be set to the size of the structure, as in
sizeof(struct sched_attr), if the provided structure is smaller
than the kernel structure, any additional fields are assumed
'0'. If the provided structure is larger than the kernel structure,
the kernel verifies all additional fields are '0' if not the
syscall will fail with -E2BIG.
As currently implemented, sched_copy_attr() returns -EFBIG for
for this case, but the logic in sys_sched_setattr() converts that
error to -EFAULT. This patch fixes the behavior.

commit aa0818c6ee8d8e4772725a43550823347bc1ad30 upstream.
When there isn't enough vring descriptor for adding to vq,
blk-mq will be put as stopped state until some of pending
descriptors are completed & freed.
Unfortunately, the vq's interrupt may come just before
blk-mq's BLK_MQ_S_STOPPED flag is set, so the blk-mq will
still be kept as stopped even though lots of descriptors
are completed and freed in the interrupt handler. The worst
case is that all pending descriptors are freed in the
interrupt handler, and the queue is kept as stopped forever.
This patch fixes the problem by starting/stopping blk-mq
with holding vq_lock.

This reverts commit 623762517e2370be3b3f95f4fe08d6c063a49b06.
Ben rightly points out that commit 0bf1457f0cfc, which is what this
original commit was reverting, never ended up in 3.14-stable, but was
only for 3.15.
So revert this patch as we now have the same check twice in a row, which
is pretty pointless. Although the comments were "prettier"...

commit f1daa838e861ae1a0fb7cd9721a21258430fcc8c upstream.
The DM cache target cannot cope with discards that span multiple cache
blocks, so each discard bio that spans more than one cache block must
get split by the DM core.

commit 80c578930ce77ba8bcfb226a184b482020bdda7b upstream.
Commit 85ad643b ("dm thin: add timeout to stop out-of-data-space mode
holding IO forever") introduced a fixed 60 second timeout. Users may
want to either disable or modify this timeout.
Allow the out-of-data-space timeout to be configured using the
'no_space_timeout' dm-thin-pool module param. Setting it to 0 will
disable the timeout, resulting in IO being queued until more data space
is added to the thin-pool.

commit 2fe2023adf695d08af5b598b2be3b288a95d563c upstream.
Undo a feature introduced in v3.14 by commit fcd46b34425d
"firewire: Enable remote DMA above 4 GB". That change raised the
minimum address at which protocol drivers and user programs can register
for request reception from 0x0001'0000'0000 to 0x8000'0000'0000.
It turned out that at least one vendor-specific protocol exists which
uses lower addresses: https://bugzilla.kernel.org/show_bug.cgi?id=76921
For the time being, revert most of commit fcd46b34425d so that affected
protocols work like with kernel v3.13 and before. Just keep the valid
documentation parts from the regressing commit, and the ability to
identify controllers which could be programmed to accept >32 bit
physical DMA addresses. The rest of fcd46b34425d should probably be
brought back as an optional instead of default feature.

commit e3beb0ac521d50d158a9d253373eae8421ac3998 upstream.
This driver is using devres managed calls incorrectly, giving the cpu0
device as first parameter instead of the cpufreq platform device.
This results in resources not being freed if the cpufreq platform device
is unbound, for example if probing has to be deferred for a missing
regulator.

commit 483a6c9d447f625b991fa04a1530493d893984db upstream.
According to the ARM ARM, the behaviour is UNPREDICTABLE if the PC read
from the exception return stack is not half word aligned. See the
pseudo code for ExceptionReturn() and PopStack().
The signal handler's address has the bit 0 set, and setup_return()
directly writes this to regs->ARM_pc. Current hardware happens to
discard this bit, but QEMU's emulation doesn't and this makes processes
crash. Mask out bit 0 before the exception return in order to get
predictable behaviour.

According to arm procedure call standart r2 register is call-cloberred.
So after the result of x expression was put into r2 any following
function call in p may overwrite r2. To fix this, the result of p
expression must be saved to the temporary variable before the

commit 4b353a706a86598ba47307c47301c3c428b79e09 upstream.
On OMAP4 panda board, there have been several bug reports about boot
hang and lock-ups with CPU_IDLE enabled. The root cause of the issue
is missing interrupts while in idle state. Commit cb7094e8 {cpuidle / omap4 :
use CPUIDLE_FLAG_TIMER_STOP flag} moved the broadcast notifiers to common
code for right reasons but on OMAP4 which suffers from a nasty ROM code
bug with GIC, commit ff999b8a {ARM: OMAP4460: Workaround for ROM bug ..},
we loose interrupts which leads to issues like lock-up, hangs etc.
Patch reverts commit cb7094 {cpuidle / omap4 : use CPUIDLE_FLAG_TIMER_STOP
flag} and 54769d6 {cpuidle: OMAP4: remove timer broadcast initialization} to
avoid the issue. With this change, OMAP4 panda boards, the mentioned
issues are getting fixed. We no longer loose interrupts which was the cause
of the regression.

commit 6aa6caff30f5dcb9e55b03b9710c30b83750cae5 upstream.
The recent change in sysfs, bcdde7e221a8750f9b62b6d0bd31b72ea4ad9309
"sysfs: make __sysfs_remove_dir() recursive" revealed an asymmetric
rphy device creation/deletion sequence in scsi_transport_sas:
modprobe mpt2sas
sas_rphy_add
device_add A rphy->dev
device_add B sas_device transport class
device_add C sas_end_device transport class
device_add D bsg class
rmmod mpt2sas
sas_rphy_delete
sas_rphy_remove
device_del B
device_del C
device_del A
sysfs_remove_group recursive sysfs dir removal
sas_rphy_free
device_del D warning
where device A is the parent of B, C, and D.
When sas_rphy_free tries to unregister the bsg request queue (device D
above), the ensuing sysfs cleanup discovers that its sysfs group has
already been removed and emits a warning, "sysfs group... not found for
kobject 'end_device-X:0'".
Since bsg creation is a side effect of sas_rphy_add, move its
complementary removal call into sas_rphy_remove. This imposes the
following tear-down order for the devices above: D, B, C, A.
Note the sas_device and sas_end_device transport class devices (B and C
above) are created and destroyed both via the list match traversal in
attribute_container_device_trigger, so the order in which they are
handled is fixed. This is fine as long as they are deleted before their
parent device.
