Subject: [GIT PULL] KVM fixes for Linux 6.9-rc3
Linus,
The following changes since commit 4cece764965020c22cff7665b18a012006359095:
Linux 6.9-rc1 (2024-03-24 14:10:05 -0700)
are available in the Git repository at:

Merge tag 'kvm-riscv-fixes-6.9-1' of https://github.com/kvm-riscv/linux into HEAD (2024-04-02 12:29:51 -0400)
----------------------------------------------------------------
ARM:
- Ensure perf events programmed to count during guest execution
are actually enabled before entering the guest in the nVHE
configuration.
- Restore out-of-range handler for stage-2 translation faults.
- Several fixes to stage-2 TLB invalidations to avoid stale
translations, possibly including partial walk caches.
- Fix early handling of architectural VHE-only systems to ensure E2H is
appropriately set.
- Correct a format specifier warning in the arch_timer selftest.
- Make the KVM banner message correctly handle all of the possible
configurations.
RISC-V:
- Remove redundant semicolon in num_isa_ext_regs().
- Fix APLIC setipnum_le/be write emulation.
- Fix APLIC in_clrip[x] read emulation.
x86:
- Fix a bug in KVM_SET_CPUID{2,} where KVM looks at the wrong CPUID entries (old
vs. new) and ultimately neglects to clear PV_UNHALT from vCPUs with HLT-exiting
disabled.
- Documentation fixes for SEV.
- Fix compat ABI for KVM_MEMORY_ENCRYPT_OP.
- Fix a 14-year-old goof in a declaration shared by host and guest; the enabled
field used by Linux when running as a guest pushes the size of "struct
kvm_vcpu_pv_apf_data" from 64 to 68 bytes. This is really unconsequential
because KVM never consumes anything beyond the first 64 bytes, but the
resulting struct does not match the documentation.
Selftests:
- Fix spelling mistake in arch_timer selftest.
