dfe6d190f3 KVM: arm64: Allow AArch32 PSTATE.M to be restored as System mode
It appears that we don't allow a vcpu to be restored in AArch32
System mode, as we *never* included it in the list of valid modes.

Just add it to the list of allowed modes.

947051e361 KVM: arm64: Fix AArch32 register narrowing on userspace write
When userspace writes to one of the core registers, we make
sure to narrow the corresponding GPRs if PSTATE indicates
an AArch32 context.

The code tries to check whether the context is EL0 or EL1 so
that it narrows the correct registers. But it does so by checking
the full PSTATE instead of PSTATE.M.

As a consequence, and if we are restoring an AArch32 EL0 context
in a 64bit guest, and that PSTATE has *any* bit set outside of
PSTATE.M, we narrow *all* registers instead of only the first 15,
destroying the 64bit state.

Obviously, this is not something the guest is likely to enjoy.

Correctly masking PSTATE to only evaluate PSTATE.M fixes it.

b0c6bcd58d xfs: Add cond_resched to block unmap range and reflink remap path
An async dio write to a sparse file can generate a lot of extents
and when we unlink this file (using rm), the kernel can be busy in umapping
and freeing those extents as part of transaction processing.

Similarly xfs reflink remapping path can also iterate over a million
extent entries in xfs_reflink_remap_blocks().

Since we can busy loop in these two functions, so let's add cond_resched()
to avoid softlockup messages like these.

With the removal of the Xilinx flashes, there is no more flash driver

special requirements like page size an opcodes.  This is already
possible by other means and it is unlikely a flash will overwrite the
(more or less complex) setup function.

d795848ecc gpio: prevent potential speculation leaks in gpio_device_get_desc()
Userspace may trigger a speculative read of an address outside the gpio
descriptor array.
Users can do that by calling gpio_ioctl() with an offset out of range.
Offset is copied from user and then used as an array index to get
the gpio descriptor without sanitization in gpio_device_get_desc().

This change ensures that the offset is sanitized by using
array_index_nospec() to mitigate any possibility of speculative
information leaks.

This bug was discovered and resolved using Coverity Static Analysis
Security Testing (SAST) by Synopsys, Inc.
