[GIT pull] Preparatory patch for semaphore cleanup

From: Thomas Gleixner
Date: Wed Sep 08 2010 - 09:11:32 EST


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
