Merge branch 'x86-irq-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip
* 'x86-irq-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip:
x86, 32-bit: Align percpu area and irq stacks to THREAD_SIZE
x86: Move alloc_desk_mask variables inside ifdef
x86-32: Align IRQ stacks properly
x86: Remove CONFIG_4KSTACKS
x86: Always use irq stacks
Fixed up trivial conflicts in include/linux/{irq.h, percpu-defs.h}

If this is the first external hardware interrupt (i.e. not a nested hardware interrupt) then the kernel switches from the current task to the interrupt stack.
