Subject: s2ram: add arch irq disable/enable hooks
From: Johannes Berg <[EMAIL PROTECTED]>
For powermac, we need to do some things between suspending devices and
device_power_off, for example setting the decrementer. This patch
allows architectures to define arch_s2ram_{en,dis}able_irqs in their
asm/suspend.h to have control over this step.
