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.
