From 933393f58fef9963eac61db8093689544e29a600 Mon Sep 17 00:00:00 2001 From: Christoph Lameter Date: Thu, 22 Dec 2011 11:58:51 -0600 Subject: percpu: Remove irqsafe_cpu_xxx variants We simply say that regular this_cpu use must be safe regardless of preemption and interrupt state. That has no material change for x86 and s390 implementations of this_cpu operations. However, arches that do not provide their own implementation for this_cpu operations will now get code generated that disables interrupts instead of preemption. -tj: This is part of on-going percpu API cleanup.
