Paolo Bonzini ea9bd29a9c Merge tag 'kvm-x86-fixes-6.14-rcN.2' of https://github.com/kvm-x86/linux into HEAD
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.
