Should this patch series also add defines for the virtual
machine control data structure changes?
1. Add the new VM-Execution Controls bit 21 as
SECONDARY_EXEC_PCOMMIT_EXITING 0x00200000
to arch/x86/include/asm/vmx.h.
2. Add the new exit reason of 64 (0x41) as
EXIT_REASON_PCOMMIT 64
to arch/x86/include/uapi/asm/vmx.h and (with a
VMX_EXIT_REASONS string) to usr/include/asm/vmx.h.
3. Add a kvm_vmx_exit_handler to arch/x86/kvm/vmx.c.
