Merge branch 'x86-irq-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 irq updates from Ingo Molnar:
"Here are the main changes in this tree:
- Introduce x86-64 IRQ/exception/debug stack guard pages to detect
stack overflows immediately and deterministically.
- Clean up over a decade worth of cruft accumulated.
The outcome of this should be more clear-cut faults/crashes when any
of the low level x86 CPU stacks overflow, instead of silent memory
corruption and sporadic failures much later on"
