The tough question for me is what > that variant name should be ;-) Tried to add preemption checks but the basic issue is that many of the checks themselves use this_cpu_ops. percpu.h is very basic to the operation of fundamental primitives for preempt etc. Use of a BUG_ON needs a seris of includes in percpu.h that cause more trouble. If I switch __this_cpu ops to check for preemption then the logic for preemption etc must use the raw_this_cpu ops. -- To unsubscribe from this list: send the line "unsubscribe linux-arch" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
