Using compile time switches for 3.0 would make it unusable for

from the beginning, it is not that hard if you take a look
at the Linux code.
I see that the ones you say can be run-time switched all add
include/asm/mach-default to the include search path as normal, and
then presumably explicitly include <asm/mach-xxx/xxx.h> where
required. Those that replace mach-default with their own include
directory in the search path presumably are forced to be a
compile-time option?
Ah, the penny drops. genapic is selected by pointing at mach-generic
directories. That certainly looks like it should port over to Xen with
little difficulty.
