Subject: [PATCH 0/8] softirq: Consolidation and stack overrun fix v3

Hi,

Series is fixed to address Linus and Ben comments:

* Turn __ARCH_IRQ_EXIT_ON_IRQ_STACK old ad-hoc style symbol to proper Kconfig
(CONFIG_HAVE_IRQ_EXIT_ON_IRQ_STACK)

* Activates it to powerpc as well.

* Fix a bit the changelog of patch 6/8

This applies on top of 06367d58f487a592de50e6e2327371c5e3b6188f
("Merge branch 'merge' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc")

And it can be pulled from:

	irq/core-v4

HEAD: 0362b2ff8d67913a8ffc5d757500129ead56b007

Frederic Weisbecker (8):
  irq: Force hardirq exit's softirq processing on its own stack
  irq: Consolidate do_softirq() arch overriden implementations
  irq: Optimize call to softirq on hardirq exit
  irq: Improve a bit softirq debugging
  irq: Justify the various softirq stack choices
  irq: Optimize softirq stack selection in irq exit
  x86: Tell about irq stack coverage
  powerpc: Tell about irq stack coverage
