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later on" * 'x86-irq-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (33 commits) x86/irq: Fix outdated comments x86/irq/64: Remove stack overflow debug code x86/irq/64: Remap the IRQ stack with guard pages x86/irq/64: Split the IRQ stack into its own pages x86/irq/64: Init hardirq_stack_ptr during CPU hotplug x86/irq/32: Handle irq stack allocation failure proper x86/irq/32: Invoke irq_ctx_init() from init_IRQ() x86/irq/64: Rename irq_stack_ptr to hardirq_stack_ptr x86/irq/32: Rename hard/softirq_stack to hard/softirq_stack_ptr x86/irq/32: Make irq stack a character array x86/irq/32: Define IRQ_STACK_SIZE x86/dumpstack/64: Speedup in_exception_stack() x86/exceptions: Split debug IST stack x86/exceptions: Enable IST guard pages x86/exceptions: Disconnect IST index and stack order x86/cpu: Remove orig_ist array x86/cpu: Prepare TSS.IST setup for guard pages x86/dumpstack/64: Use cpu_entry_area instead of orig_ist x86/irq/64: Use cpu entry area instead of orig_ist x86/traps: Use cpu_entry_area instead of orig_ist ...
