fc04c39bae io-wq: fix IO_WQ_WORK_NO_CANCEL cancellation
To cancel a work, io-wq sets IO_WQ_WORK_CANCEL and executes the
callback. However, IO_WQ_WORK_NO_CANCEL works will just execute and may
return next work, which will be ignored and lost.

Cancel the whole link.

9abd515a6e arm64: context: Fix ASID limit in boot messages
Since commit f88f42f853 ("arm64: context: Free up kernel ASIDs if KPTI
is not in use"), the NUM_USER_ASIDS macro doesn't correspond to the
effective number of ASIDs when KPTI is enabled. Get an accurate number
of available ASIDs in an arch_initcall, once we've discovered all CPUs'
capabilities and know if we still need to halve the ASID space for KPTI.

0b1570b7ff drm/i915: Protect i915_request_await_start from early waits
We need to be extremely careful inside i915_request_await_start() as it
needs to walk the list of requests in the foreign timeline with very
little protection. As we hold our own timeline mutex, we can not nest
inside the signaler's timeline mutex, so all that remains is our RCU
protection. However, to be safe we need to tell the compiler that we may
be traversing the list only under RCU protection, and furthermore we
need to start declaring requests as elements of the timeline from their
construction.

Wa_1608008084 is an additional WA that applies to writes on FF_MODE2
register. We can't read it back either from CPU or GPU. Since the other
bits should be 0, recommendation to handle Wa_1604555607 is to actually
just write the timer value.

Do a write only and don't try to read it, neither before or after
the WA is applied.

33e059a2e4 drm/i915/psr: Force PSR probe only after full initialization
Commit 60c6a14b48 ("drm/i915/display: Force the state compute phase
once to enable PSR") was forcing the state compute too earlier
causing errors because not everything was initialized, so here
moving to the end of i915_driver_modeset_probe() when the display is
all initialized.

Also fixing the place where it disarm the force probe as during the
atomic check phase errors could happen like the ones due locking and
it would cause PSR to never be enabled if that happens.
Leaving the disarm to the atomic commit phase, intel_psr_enable() or
intel_psr_update() will be called even if the current state do not
allow PSR to be enabled.

v2: Check if intel_dp is null in intel_psr_force_mode_changed_set()
v3: Check intel_dp before get dev_priv
v4:
- renamed intel_psr_force_mode_changed_set() to
intel_psr_set_force_mode_changed()
- removed the set parameter from intel_psr_set_force_mode_changed()
- not calling intel_psr_set_force_mode_changed() from
intel_psr_enable/update(), directly setting it after the same checks
that intel_psr_set_force_mode_changed() does
- moved intel_psr_set_force_mode_changed() arm call to
i915_driver_modeset_probe() as it is a better for a PSR call, all the
functions calls happening between the old and the new function call
will cause issue

86f7e90ce8 KVM: VMX: check descriptor table exits on instruction emulation
KVM emulates UMIP on hardware that doesn't support it by setting the
'descriptor table exiting' VM-execution control and performing
instruction emulation. When running nested, this emulation is broken as
KVM refuses to emulate L2 instructions by default.

Correct this regression by allowing the emulation of descriptor table
instructions if L1 hasn't requested 'descriptor table exiting'.

37b0b6b8b9 ext4: potential crash on allocation error in ext4_alloc_flex_bg_array()
If sbi->s_flex_groups_allocated is zero and the first allocation fails
then this code will crash.  The problem is that "i--" will set "i" to
-1 but when we compare "i >= sbi->s_flex_groups_allocated" then the -1
is type promoted to unsigned and becomes UINT_MAX.  Since UINT_MAX
is more than zero, the condition is true so we call kvfree(new_groups[-1]).
The loop will carry on freeing invalid memory until it crashes.

38b17afb0e macintosh: therm_windtunnel: fix regression when instantiating devices
Removing attach_adapter from this driver caused a regression for at
least some machines. Those machines had the sensors described in their
DT, too, so they didn't need manual creation of the sensor devices. The
old code worked, though, because manual creation came first. Creation of
DT devices then failed later and caused error logs, but the sensors
worked nonetheless because of the manually created devices.

When removing attach_adaper, manual creation now comes later and loses
the race. The sensor devices were already registered via DT, yet with
another binding, so the driver could not be bound to it.

This fix refactors the code to remove the race and only manually creates
devices if there are no DT nodes present. Also, the DT binding is updated
to match both, the DT and manually created devices. Because we don't
know which device creation will be used at runtime, the code to start
the kthread is moved to do_probe() which will be called by both methods.

bba42affa7 x86/mm: Fix dump_pagetables with Xen PV
Commit 2ae27137b2 ("x86: mm: convert dump_pagetables to use
walk_page_range") broke Xen PV guests as the hypervisor reserved hole in
the memory map was not taken into account.

Fix that by starting the kernel range only at GUARD_HOLE_END_ADDR.

99bcd4a6e5 x86/ioperm: Add new paravirt function update_io_bitmap()
Commit 111e7b15cf ("x86/ioperm: Extend IOPL config to control ioperm()
as well") reworked the iopl syscall to use I/O bitmaps.

Unfortunately this broke Xen PV domains using that syscall as there is
currently no I/O bitmap support in PV domains.

Add I/O bitmap support via a new paravirt function update_io_bitmap which
Xen PV domains can use to update their I/O bitmaps via a hypercall.

spi: atmel-quadspi: fix possible MMIO window size overrun
The QSPI controller memory space is limited to 128MB:
0x9000_00000-0x9800_00000/0XD000_0000--0XD800_0000.

There are nor flashes that are bigger in size than the memory size
supported by the controller: Micron MT25QL02G (256 MB).

Check if the address exceeds the MMIO window size. An improvement
would be to add support for regular SPI mode and fall back to it
when the flash memories overrun the controller's memory space.

ASoC: dapm: Correct DAPM handling of active widgets during shutdown
commit c2caa4da46 ("ASoC: Fix widget powerdown on shutdown") added a
set of the power state during snd_soc_dapm_shutdown to ensure the
widgets powered off. However, when commit 39eb5fd13d
("ASoC: dapm: Delay w->power update until the changes are written")
added the new_power member of the widget structure, to differentiate
between the current power state and the target power state, it did not
update the shutdown to use the new_power member.

As new_power has not updated it will be left in the state set by the
last DAPM sequence, ie. 1 for active widgets. So as the DAPM sequence
for the shutdown proceeds it will turn the widgets on (despite them
already being on) rather than turning them off.
