  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.
