The patch titled
semaphore: __down_common: use signal_pending_state()
has been removed from the -mm tree. Its filename was
semaphore-__down_common-use-signal_pending_state.patch

Subject: semaphore: __down_common: use signal_pending_state()
From: Oleg Nesterov <oleg@xxxxxxxxxx>
Change __down_common() to use signal_pending_state() instead of open
coding.
The changes in kernel/semaphore.o are just artifacts, the state checks are
optimized away.
