(xen) stable/ia64, stable/blkfront-cleanup, and stable/cleanup for 2.6.39

Hey Linus,

Please pull these three branches:

git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen.git stable/ia64 stable/blkfront-cleanup stable/cleanup

Or you take #for-2.6.39/cleanup which has these three merges (no conflicts) for your convience.

Back to the description.

#stable/irq.rework is based off v2.6.38-rc6 (f5412be599602124d2bdd49947b231dd77c0bf99)

.. fixes a build-time mess up on IA64 when using Xen there.

#stable/blkfront-cleanup is based off v2.6.38-rc1 (c56eb8fb6dccb83d9fe62fd4dc00c834de9bc470)

.. and it shuffles a struct around for further work.

#stable/cleanup is based off v2.6.38-rc4 (100b33c8bd8a3235fd0b7948338d6cbb3db3c63d)

.. and it does a general cleanup of compile warnings.
