To cover scenarios where the scope of the guard differs from the scope

Here is an example use for a conditionally activated guard variable:

void func(bool a)
{
	DEFINE_INACTIVE_GUARD(preempt_notrace, myguard);

	[...]
	if (a) {
		might_sleep();
		activate_guard(preempt_notrace, myguard)();

Hi Mathieu,

The three cleanup patches fail to apply (I believe one has already been
fixed by Ingo too). Could you have the clean up patches be a separate
series that is likely to get in, especially since it's more of a moving
target.

Thanks,
