No #ifdefs; put them in xen.h if necessary (which they aren't). This
probably isn't the right header anyway; this is specifically for testing
the presence of Xen and/or the current domain type. It shouldn't have
any other prototypes in it, or include anything else (it probably
already includes too much). Given this is already x86-specific code,
include asm/xen/something.h.

Again, no #ifdefs here. Put an #ifdeffed stub in an appropriate header.
