[GIT pull] irq cleanups for .39

From: Thomas Gleixner
Date: Fri Mar 25 2011 - 12:53:15 EST

Linus,

Please pull the latest irq-cleanup-for-linus git tree from:

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

This contains the irq/urgent bits which Ingo asked to pull earlier, so
whatever you pull first does not matter.

The gpio patches have been acked by Grant.

The avr, h8300, xtensa, m32r, um bits is stuff which got ignored by
the arch maintainers. Those archs seem to be orphaned.

The cleanup is necessary as we really want to get rid of all the
deprecated and compat stuff asap.

Thanks,

tglx
