[PATCH 2/2] KVM: VMX: Use vmread_error() to report VM-Fail in "goto" path

From: Sean Christopherson
Date: Fri Jul 21 2023 - 19:56:54 EST


Use vmread_error() to report VM-Fail on VMREAD for the "asm goto" case,
now that trampoline case has yet another wrapper around vmread_error() to
play nice with instrumentation.
