Remove x86 dependency in drivers/xen/events.c for ia64/xen support introducing include/asm/xen/events.h. Introduce xen_irqs_disabled() to hide regs->flags Introduce xen_do_IRQ() to hide regs->orig_ax. make enum ipi_vector definition arch specific. ia64/xen needs four vectors. Add one rmb() because on ia64 xchg() isn't barrier.

Iirc I derived this from a prior commit from either Ian or Jeremy. Didn''t really check it out, so there''s very likely a more correct fix than what''s attached here. /local/exp/dns/scratch/xenbits/xen-unstable.hg/linux-2.6-pvops.git/arch/x86/xen/time.c: In function ''xen_setup_timer'':

Hi. Recently the xen-ia64 community started to make efforts to merge xen/ia64 Linux to upstream. The first step is to merge up domU portion. This patchset is preliminary for xen/ia64 domU linux making the current xen/x86 domU code more arch generic and adding missing definitions and files.
