Paolo Bonzini ea9bd29a9c KVM x86 fixes for 6.14-rcN #2
- 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.
