Pull kvm fixes from Paolo Bonzini:
"Arm:
- Make sure we don't leak any S1POE state from guest to guest when
the feature is supported on the HW, but not enabled on the host
- Propagate the ID registers from the host into non-protected VMs
managed by pKVM, ensuring that the guest sees the intended feature
set
- Drop double kern_hyp_va() from unpin_host_sve_state(), which could
bite us if we were to change kern_hyp_va() to not being idempotent
- Don't leak stage-2 mappings in protected mode
- Correctly align the faulting address when dealing with single page
stage-2 mappings for PAGE_SIZE > 4kB
- Fix detection of virtualisation-capable GICv5 IRS, due to the
maintainer being obviously fat fingered... [his words, not mine]
- Remove duplication of code retrieving the ASID for the purpose of
S1 PT handling
- Fix slightly abusive const-ification in vgic_set_kvm_info()
Generic:
- Remove internal Kconfigs that are now set on all architectures
- Remove per-architecture code to enable KVM_CAP_SYNC_MMU, all
architectures finally enable it in Linux 7.0"

Pull arm64 fixes from Will Deacon:
"The diffstat is dominated by changes to our TLB invalidation errata
handling and the introduction of a new GCS selftest to catch one of
the issues that is fixed here relating to PROT_NONE mappings.
- Fix cpufreq warning due to attempting a cross-call with interrupts
masked when reading local AMU counters
- Fix DEBUG_PREEMPT warning from the delay loop when it tries to
access per-cpu errata workaround state for the virtual counter
- Re-jig and optimise our TLB invalidation errata workarounds in
preparation for more hardware brokenness
- Fix GCS mappings to interact properly with PROT_NONE and to avoid
corrupting the pte on CPUs with FEAT_LPA2
- Fix ioremap_prot() to extract only the memory attributes from the
user pte and ignore all the other 'prot' bits"
