Subject: [GIT pull] Preparatory patch for semaphore cleanup

Linus,

Please pull the semaphore-for-linus git tree from:

   git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip.git semaphore-for-linus

This patch just provides the DEFINE_SEMAPHORE macro which is required
for the various subsystem cleanups I sent out, so we can finally get
rid of init_MUTEX[_LOCKED] in 2.6.37.

Thanks,

	tglx
