move the following files to guest folder:
renamed:    arch/x86/assign.c -> arch/x86/guest/assign.c
renamed:    arch/x86/ept.c -> arch/x86/guest/ept.c
renamed:    arch/x86/io_emul.c -> arch/x86/guest/io_emul.c
renamed:    arch/x86/trusty.c -> arch/x86/guest/trusty.c
renamed:    arch/x86/virq.c -> arch/x86/guest/virq.c
renamed:    arch/x86/virtual_cr.c -> arch/x86/guest/virtual_cr.c
renamed:    arch/x86/vmcs.c -> arch/x86/guest/vmcs.c
renamed:    arch/x86/vmexit.c -> arch/x86/guest/vmexit.c
renamed:    arch/x86/vmx_asm.S -> arch/x86/guest/vmx_asm.S
renamed:    include/arch/x86/assign.h ->
	    include/arch/x86/guest/assign.h
renamed:    include/arch/x86/io_emul.h ->
	    include/arch/x86/guest/io_emul.h
renamed:    include/arch/x86/trusty.h ->
            include/arch/x86/guest/trusty.h
renamed:    include/arch/x86/virtual_cr.h ->
            include/arch/x86/guest/virtual_cr.h
renamed:    include/arch/x86/vmcs.h -> include/arch/x86/guest/vmcs.h
renamed:    include/arch/x86/vmexit.h ->
            include/arch/x86/guest/vmexit.h

After these files movement, all the files in arch/x86 are native
hardware related, and all the files in arch/x86/guest are
virtualiztion related.
