Ralf,

please pull that change from

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

so you can apply David's patches which depend on that one.

That's 38-rc4 based w/o any other changes to the core code. I pull
that into irq/core so we have no dependecies or collision for Linus.

Thanks,

	tglx
