Pull KVM fixes from Paolo Bonzini:
 "arm64:

   - Fix a couple of bugs affecting pKVM's PSCI relay implementation
     when running in the hVHE mode, resulting in the host being entered
     with the MMU in an unknown state, and EL2 being in the wrong mode

  x86:

   - Set RFLAGS.IF in C code on SVM to get VMRUN out of the STI shadow

   - Ensure DEBUGCTL is context switched on AMD to avoid running the
     guest with the host's value, which can lead to unexpected bus lock
     #DBs

   - Suppress DEBUGCTL.BTF on AMD (to match Intel), as KVM doesn't
     properly emulate BTF. KVM's lack of context switching has meant BTF
     has always been broken to some extent

   - Always save DR masks for SNP vCPUs if DebugSwap is *supported*, as
     the guest can enable DebugSwap without KVM's knowledge

   - Fix a bug in mmu_stress_tests where a vCPU could finish the "writes
     to RO memory" phase without actually generating a write-protection
     fault

   - Fix a printf() goof in the SEV smoke test that causes build
     failures with -Werror

   - Explicitly zero EAX and EBX in CPUID.0x8000_0022 output when
     PERFMON_V2 isn't supported by KVM"
