Makes sense. In fact I would say any array with NR_CPUS elements

"__cacheline_aligned" padding.
However, we don't have a standard infrastructure for that in Xen right
now, and that means that IA64's hardirq.h, part of the weird
suck-in-headers-from-Linux thing, is radically different from x86 (and
thus PPC). And *that* means it's quite difficult to make any changes
to hardirq.h without fear of breaking the IA64 build.
I'm going to pull in percpu support after 3.0.2.
