| H A D | idle.c | 2525db04 Tue Jun 13 08:05:46 CDT 2017 Nicholas Piggin <npiggin@gmail.com> powerpc/powernv: Simplify lazy IRQ handling in CPU offline
Rather than concern ourselves with any soft-mask logic in the CPU
hotplug handler, just hard disable interrupts. This ensures there
are no lazy-irqs pending, which means we can call directly to idle
instruction in order to sleep.
