Unlike x86 and apparently ia64, PowerPC delivers timer interrupts as a 
different exception than device interrupts. For PowerPC Xen, we emulate this 
exception rather than delivering timer events as virtual IRQs. This patch 
introduces no functional changes for x86 and ia64, but is a required change 
for xen/arch/ppc.
