This reverts the earlier fix attempt and works around the problem by including both linux/mmu_context.h and asm/mmu_context.h from kernel/sched/core.c. This is not a good solution but seems less hacky than the alternatives.
What about simply not compiling finish_arch_post_lock_switch() when building modules? (untested, not compiled or anything) Signed-off-by: Steven Rostedt <rostedt@goodmis.org> ---
