From: Peter Huewe <peterhuewe@gmx.de>

This patch fixes a build failure[1], by adding the missing semaphore.h include

References:
[1] http://kisskb.ellerman.id.au/kisskb/buildresult/2234322/

Patch against linux-next as of 20100306
Applies smoothly to Linus' tree as well.
The build failure happens to be only in linux-next yet.
