Merge tag 'ia64-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/aegl/linux

Pull miscellaneous Itanium patches from Tony Luck.

The conflicts in arch/ia64/hp/sim/simserial.c were due to patches to
simserial that had alredy been included (with lots of further cleanups)
in the serial tree.
