I applied the interrupt related changes in the tip tree. They are on a
seperate rc1 based branch and contain no other changes so that they can
be pulled into the PCI tree as prerequisite for the actual endpoint
changes. This can be pulled from the following tag:

   git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git irq-platform-msi-05-08-25
