[PATCH 0/2] KVM: VMX: Use basic exit reason for cheking and indexing

[Xiaoyao Li <xiaoyao.li@intel.com>]

Current KVM directly uses the whole 32-bit EXIT REASON when
1) checking: if (vmx->exit_reason == EXIT_REASON_*)
2) indexing: kvm_vmx_exit_handlers[exit_reason]

However, only the low 16-bit of EXIT REASON serves as basic Exit Reason.
Fix it by using the 16-bit basic exit reason.

BTW, I'm not sure if it's necessary to split nested case into a seperate
patch.

Xiaoyao Li (2):
  kvm: vmx: Use basic exit reason to check if it's the specific VM EXIT
  kvm: nvmx: Use basic(exit_reason) when checking specific EXIT_REASON
