Merge branch 'irq-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull irq fixes and cleanups from Thomas Gleixner:
"Commit e5ab012c3271 ("nohz: Make tick_nohz_irq_exit() irq safe") is
the first commit in the series and the minimal necessary bugfix, which
needs to go back into stable.
The remanining commits enforce irq disabling in irq_exit(), sanitize
the hardirq/softirq preempt count transition and remove a bunch of no
longer necessary conditionals."
I personally love getting rid of the very subtle and confusing
IRQ_EXIT_OFFSET thing. Even apart from the whole "more lines removed
than added" thing.
* 'irq-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
irq: Don't re-enable interrupts at the end of irq_exit
irq: Remove IRQ_EXIT_OFFSET workaround
Revert "nohz: Make tick_nohz_irq_exit() irq safe"
irq: Sanitize invoke_softirq
irq: Ensure irq_exit() code runs with interrupts disabled
nohz: Make tick_nohz_irq_exit() irq safe
