afs_put_addrlist() casts kfree() to rcu_callback_t. Apart from being wrong
in theory, this might also blow up when people start enforcing function

Commit 263dde869b ("xfs: cleanup xfs_dir2_block_getdents") introduced
a getdents regression, when it converted the pointer arithmetics to
offset calculations: offset is updated in the loop already for the next
iteration, but the updated offset value is used incorrectly in two
places, where we should have used the not-yet-updated value.
This caused for example "git clean -ffdx" failures to cleanup certain
directory structures when running in a container.
Fix the regression by making sure we use proper offset in the loop body.
Thanks to Christoph Hellwig for suggestion how to best fix the code.

The KVM hyp code is only run after system capabilities have been
finalized, and thus all const cap checks have been patched. This is
noted in in __cpu_init_hyp_mode(), where we BUG() if called too early:
| /*
| * Call initialization code, and switch to the full blown HYP code.
| * If the cpucaps haven't been finalized yet, something has gone very
| * wrong, and hyp will crash and burn when it uses any
| * cpus_have_const_cap() wrapper.
| */
Given this, the hyp code can use cpus_have_final_cap() and avoid
generating code to check the cpu_hwcaps array, which would be unsafe to
run in hyp context.
This patch migrate the KVM hyp code to cpus_have_final_cap(), avoiding
this redundant code generation, and making it possible to detect if we
accidentally invoke this code too early. In the latter case, the BUG()
in cpus_have_final_cap() will cause a hyp panic.

When cpus_have_const_cap() was originally introduced it was intended to
be safe in hyp context, where it is not safe to access the cpu_hwcaps
array as cpus_have_cap() did. For more details see commit:
a4023f6827 ("arm64: Add hypervisor safe helper for checking constant capabilities")
We then made use of cpus_have_const_cap() throughout the kernel.
Subsequently, we had to defer updating the static_key associated with
each capability in order to avoid lockdep complaints. To avoid breaking
kernel-wide usage of cpus_have_const_cap(), this was updated to fall
back to the cpu_hwcaps array if called before the static_keys were
updated. As the kvm hyp code was only called later than this, the
fallback is redundant but not functionally harmful. For more details,
see commit:
63a1e1c95e ("arm64/cpufeature: don't use mutex in bringup path")
Today we have more users of cpus_have_const_cap() which are only called
once the relevant static keys are initialized, and it would be
beneficial to avoid the redundant code.
To that end, this patch adds a new cpus_have_final_cap(), helper which
is intend to be used in code which is only run once capabilities have
been finalized, and will never check the cpus_hwcap array. This helps
the compiler to generate better code as it no longer needs to generate
code to address and test the cpus_hwcap array. To help catch misuse,
cpus_have_final_cap() will BUG() if called before capabilities are
finalized.
In hyp context, BUG() will result in a hyp panic, but the specific BUG()
instance will not be identified in the usual way.
Comments are added to the various cpus_have_*_cap() helpers to describe
the constraints on when they can be used. For clarity cpus_have_cap() is
moved above the other helpers. Similarly the helpers are updated to use
system_capabilities_finalized() consistently, and this is made
__always_inline as required by its new callers.

The descriptions for the spi-rx-bus-width and spi-tx-bus-width
properties refer to "MISO" and "MOSI", which are not explained in the
document. While these abbreviations are fairly common when talking
about SPI, and thus may not need an explanation, they are not entirely
correct in this context, as the SPI controller may be used in slave mode
instead of master mode.
Fix this by replacing them by "read transfers" resp. "write transfers",
like is done for the spi-rx-delay-us and spi-tx-delay-us properties.

confused stepping applicability on ICL). Ultimately it appears we

Note that this is identical to Wa_1407928979:tgl that already exists in
our driver too...yet another number referencing the same actual
workaround.

On those boards, as stated in schematics files, the regulator used for IOs
is VDD. It was wrongly set to v3v3.
