preempt/dynamic: Provide preempt_schedule[_notrace]() static calls
Provide static calls to control preempt_schedule[_notrace]() (called in CONFIG_PREEMPT) so that we can override their behaviour when preempt= is overriden. Since the default behaviour is full preemption, both their calls are initialized to the arch provided wrapper, if any. [fweisbec: only define static calls when PREEMPT_DYNAMIC, make it less dependent on x86 with __preempt_schedule_func] Signed-off-by:Peter Zijlstra (Intel) <peterz@infradead.org> Signed-off-by:
