Merge branch 'irq-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull irq core updates from Thomas Gleixner:
"Managerial summary:
Core code:
- final removal of IRQF_DISABLED
- new state save/restore functions for virtualization support
- wakeup support for stacked irqdomains
- new function to solve the netpoll synchronization problem
irqchips:
- new driver for STi based devices
- new driver for Vybrid MSCM
- massive cleanup of the GIC driver by moving the GIC-addons to
stacked irqdomains
- the usual pile of fixes and updates to the various chip drivers"
