[PATCH] ppc64: update irq affinity mask when migrating irqs
This patch is from Nathan Lynch <ntl@pobox.com>.
When offlining a cpu, any device interrupts which are bound to the cpu
have their affinity forcibly reset to all cpus (the default).
However, the value in /proc/irq/XXX/smp_affinity remains unchanged.
Since we're doing this while all the other cpus are stopped, it should
be safe to just call desc->handler->set_affinity and manually update
the irq_affinity array.
