Pull xfs cleanup from Carlos Maiolino:

xfs: Use abs_diff instead of XFS_ABSDIFF

Instead of creating and initializing _all_ hyp vcpus in pKVM when
the first host vcpu runs for the first time, initialize _each_
hyp vcpu in conjunction with its corresponding host vcpu.
Some of the host vcpu state (e.g., system registers and traps
values) is not initialized until the first time the host vcpu is
run. Therefore, initializing a hyp vcpu before its corresponding
host vcpu has run for the first time might not view the complete
host state of these vcpus.
Additionally, this behavior is inline with non-protected modes.

Move the code that creates and initializes the hyp view of a vcpu
in pKVM to its own function. This is meant to make the transition
to initializing every vcpu individually clearer.

Factor out the code for setting a vcpu's HCRX_EL2 traps in to a
separate inline function. This allows us to share the logic with
pKVM when setting the traps in protected mode.
No functional change intended.

Remove `pr_debug` calls which emit information already contained in
`pr_warn` calls that occur on test failure. This reduces unhelpful test
verbosity.
Note that a `pr_debug` removed from `_check_numbers_template` appears to
have been the only guard against silent false positives, but in fact
this condition is handled in `_test`; it is only possible for `n_args`
to be `0` in `_check_numbers_template` if the test explicitly expects it
*and* `vsscanf` returns `0`, matching the expectation.

disable_irq_nosync_lockdep() disables interrupts with lockdep enabled to
avoid false positive reports by lockdep that a certain lock has not been
acquired with disabled interrupts. The user of this macros expects that
a lock can be acquried without disabling interrupts because the IRQ line
triggering the interrupt is disabled.
This triggers a warning on PREEMPT_RT because after
disable_irq_nosync_lockdep.*() the following spinlock_t now is acquired
with disabled interrupts.
On PREEMPT_RT there is no difference between spin_lock() and
spin_lock_irq() so avoiding disabling interrupts in this case works for
the two remaining callers as of today.
Don't disable interrupts on PREEMPT_RT in disable_irq_nosync_lockdep.*().

Downstream Linux, and consequently both downstream and mainline TF-A,
all use a different set of clock IDs from mainline Linux. If we want to
fiddle with these clocks through SCMI, we'll need to use the right IDs.
If we don't do this we'll end up changing unrelated clocks all over the
place.
Change the clock IDs to the newly added SCMI clock IDs for the CPU and
GPU nodes, which are currently the only ones using SCMI clocks. This
fixes the terrible GPU performance, as we weren't reclocking it
properly.

KVM_CAP_SYNC_REGS does not make sense for VMs with protected guest state,
since the register values cannot actually be written. Return 0
when using the VM-level KVM_CHECK_EXTENSION ioctl, and accordingly
return -EINVAL from KVM_RUN if the valid/dirty fields are nonzero.
However, on exit from KVM_RUN userspace could have placed a nonzero
value into kvm_run->kvm_valid_regs, so check guest_state_protected
again and skip store_regs() in that case.

When comparing to the ARM list [1], it appears that several ARM cores
were missing from the lists in spectre_bhb_loop_affected(). Add them.
NOTE: for some of these cores it may not matter since other ways of
clearing the BHB may be used (like the CLRBHB instruction or ECBHB),
but it still seems good to have all the info from ARM's whitepaper
included.

The code for detecting CPUs that are vulnerable to Spectre BHB was
based on a hardcoded list of CPU IDs that were known to be affected.
Unfortunately, the list mostly only contained the IDs of standard ARM
cores. The IDs for many cores that are minor variants of the standard
ARM cores (like many Qualcomm Kyro CPUs) weren't listed. This led the
code to assume that those variants were not affected.
Flip the code on its head and instead assume that a core is vulnerable
if it doesn't have CSV2_3 but is unrecognized as being safe. This
involves creating a "Spectre BHB safe" list.
As of right now, the only CPU IDs added to the "Spectre BHB safe" list
are ARM Cortex A35, A53, A55, A510, and A520. This list was created by
looking for cores that weren't listed in ARM's list [1] as per review
feedback on v2 of this patch [2]. Additionally Brahma A53 is added as
per mailing list feedback [3].
NOTE: this patch will not actually _mitigate_ anyone, it will simply
cause them to report themselves as vulnerable. If any cores in the
system are reported as vulnerable but not mitigated then the whole
system will be reported as vulnerable though the system will attempt
to mitigate with the information it has about the known cores.

Add guest_tsc_protected member to struct kvm_arch_vcpu and prohibit
changing TSC offset/multiplier when guest_tsc_protected is true.
X86 confidential computing technology defines protected guest TSC so that
the VMM can't change the TSC offset/multiplier once vCPU is initialized.
SEV-SNP defines Secure TSC as optional, whereas TDX mandates it.
KVM has common logic on x86 that tries to guess or adjust TSC
offset/multiplier for better guest TSC and TSC interrupt latency
at KVM vCPU creation (kvm_arch_vcpu_postcreate()), vCPU migration
over pCPU (kvm_arch_vcpu_load()), vCPU TSC device attributes
(kvm_arch_tsc_set_attr()) and guest/host writing to TSC or TSC adjust MSR
(kvm_set_msr_common()).
The current x86 KVM implementation conflicts with protected TSC because the
VMM can't change the TSC offset/multiplier.
Because KVM emulates the TSC timer or the TSC deadline timer with the TSC
offset/multiplier, the TSC timer interrupts is injected to the guest at the
wrong time if the KVM TSC offset is different from what the TDX module
determined.
Originally this issue was found by cyclic test of rt-test [1] as the
latency in TDX case is worse than VMX value + TDX SEAMCALL overhead. It
turned out that the KVM TSC offset is different from what the TDX module
determines.
Disable or ignore the KVM logic to change/adjust the TSC offset/multiplier
somehow, thus keeping the KVM TSC offset/multiplier the same as the
value of the TDX module. Writes to MSR_IA32_TSC are also blocked as
they amount to a change in the TSC offset.

TDX needs to free the TDR control structures last, after all paging structures
have been torn down; move the vm_destroy callback at a suitable place.
The new place is also okay for AMD; the main difference is that the
MMU has been torn down and, if anything, that is better done before
the SNP ASID is released.
