Series KVM: x86: Fixes for KVM_INTEL_PROVE_VE | expand

Commit Message

Sean Christopherson May 18, 2024, 12:04 a.m. UTC 
Always handle #VEs, e.g. due to prove EPT Violation #VE failures, in L0,
as KVM does not expose any #VE capabilities to L1, i.e. any and all #VEs
are KVM's responsibility.

Fixes: 8131cf5b4fd8 ("KVM: VMX: Introduce test mode related to EPT violation VE")
