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.
