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. For detailed discussion of the subject, please refer to the following thread. http://thread.gmane.org/gmane.linux.kernel/1222078 Signed-off-by: Christoph Lameter <cl@linux.com> Signed-off-by: Tejun Heo <tj@kernel.org> LKML-Reference: <alpine.DEB.2.00.1112221154380.11787@router.home>
