The sleeping functions down, down_interruptible, down_killable and
down_timeout can't be called with interrupts disabled, so we don't have to
save and restore interrupt flag.
This patch avoids the costly pushf and popf instructions on the semaphore
path.

The sleeping functions down, down_interruptible, down_killable and
down_timeout can't be called with interrupts disabled, so we don't have to
save and restore interrupt flag.
This patch avoids the costly pushf and popf instructions on the semaphore
path.
