I think TIF_NOTIFY_SIGNAL can have more users. Say, we can move
try_to_freeze() from get_signal() to tracehook_notify_signal(), kill
fake_signal_wake_up(), and remove freezing() from recalc_sigpending().
Probably the same for TIF_PATCH_PENDING, klp_send_signals() can use
set_notify_signal() rather than signal_wake_up().
Oleg.
