Subject: [GIT PULL] irq fixes
Linus,
Please pull the latest irq-fixes-for-linus git tree from:
git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip.git irq-fixes-for-linus
Thanks,
Ingo
------------------>
Dan Carpenter (1):
genirq: Fix incorrect unlock in __setup_irq()
Thomas Gleixner (4):
cris: Fix irq conversion fallout
cris: Use accessor functions to set IRQ_PER_CPU flag
genirq: show_interrupts: Check desc->name before printing it blindly
cris: Use generic show_interrupts()
