With the previous two fixes for the write / ioctl races:

ALSA: seq: More protection for concurrent write and ioctl races
the cells aren't any longer in queues at the point calling
snd_seq_pool_done() in snd_seq_ioctl_set_client_pool(). Hence the

This patch is an attempt for further hardening against races between
the concurrent write and ioctls. The previous fix d15d662e89
("ALSA: seq: Fix racy pool initializations") covered the race of the
pool initialization at writer and the pool resize ioctl by the
client->ioctl_mutex (CVE-2018-1000004). However, basically this mutex
should be applied more widely to the whole write operation for
avoiding the unexpected pool operations by another thread.
The only change outside snd_seq_write() is the additional mutex
argument to helper functions, so that we can unlock / relock the given
mutex temporarily during schedule() call for blocking write.

This is a fix for a (sort of) fallout in the recent commit
d15d662e89 ("ALSA: seq: Fix racy pool initializations") for
CVE-2018-1000004.
As the pool resize deletes the existing cells, it may lead to a race
when another thread is writing concurrently, eventually resulting a
UAF.
A simple workaround is not to allow the pool resizing when the pool is
in use. It's an invalid behavior in anyway.

This reverts commit 4828296982 which
caused the following issues:
1. On T460p with BIOS version 2.22 touchpad and trackpoint stop working
after suspend-resume cycle. Due to strange state of the device another
suspend is impossible.
The following dmesg errors can be observed:
thinkpad_acpi: EC reports that Thermal Table has changed

2. On another T460p with BIOS version 2.15 two finger scrolling gesture
on the touchpad stops working after suspend-resume cycle (about 75%
reproducibility, when it still works, the scrolling gesture becomes
laggy). Nothing suspicious appears in the dmesg.
Analysis form Richard Schütz:
"RMI is unreliable on the ThinkPad T460p because the device is affected
by the firmware behavior addressed in a7ae81952c ("i2c: i801: Allow
ACPI SystemIO OpRegion to conflict with PCI BAR")."
The affected devices often show:

This platform was only one phone Jack.
Add dummy lineout verb to fix automute mode disable.
This just the workaround.
[ More background information:
since the platform has only a headphone jack without speaker, the
driver doesn't create the auto-mute control. Meanwhile we do update
the headset mode via the automute hook in the driver, thus with this
setup, the headset won't be updated any longer.
By adding a dummy line-out pin here, the auto-mute is added by the
driver, and the headset update is triggered properly.

when a system call is interrupted we might call the critical section

Commit a3e6c1eff5 ("MIPS: IRQ: Fix disable_irq on CPU IRQs") fixes an
issue where disable_irq did not actually disable the irq. The bug caused
our IPIs to not be disabled, which actually is the correct behavior.
With the addition of commit a3e6c1eff5 ("MIPS: IRQ: Fix disable_irq on
CPU IRQs"), the IPIs were getting disabled going into suspend, thus
schedule_ipi() was not being called. This caused deadlocks where
schedulable task were not being scheduled and other cpus were waiting
for them to do something.
Add the IRQF_NO_SUSPEND flag so an irq_disable will not be called on the
IPIs during suspend.

context from vmbus, there is no need to do irqsave/restore.

There is a race between napi_reschedule and re-enabling interrupts
which could lead to missed host interrrupts. This occurs when
interrupts are re-enabled (hv_end_read) and vmbus irq callback
(netvsc_channel_cb) has already scheduled NAPI.

Block setup of multiple channels earlier in the teardown
process. This avoids possible races between halt and subchannel
initialization.
