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"
