Subject: [PATCH 0/2] KVM: VMX: Make VMREAD error trampoline noinstr friendly

Add another trampoline for the CONFIG_CC_HAS_ASM_GOTO_OUTPUT=n VMREAD error
path in order to enable instrumentation, i.e. to make objtool happy, before
calling pr_warn_ratelimited().

Sean Christopherson (2):
  KVM: VMX: Make VMREAD error path play nice with noinstr
  KVM: VMX: Use vmread_error() to report VM-Fail in "goto" path
