RE: [Xen-devel] Genapic

Genapic is done differently for i386 and x86_64 in the LK. In i386 it is
machine specific and in x86_64 it is APIC model specific. Do you want
Xen to mimic that? Further more both i386 and x86_64 have separate
apic.c, io_apic.c (just to name a couple) files. Xen shares them between
the two. Will that cause any problems? 

I am wondering if it is possible to have a unified genapic for Xen. Or
is it way too complicated?

I didn't realise that most of the genapic targets are trivially 
run-time selectable. That being the case, I'm happy for you to make 
es7000 run-time selected right now.
