 "After stopping the full x86/apic branch, I took some time to go
  through the first block of patches again, which are mostly cleanups
  and preparatory work for the irqdomain conversion and ioapic hotplug
  support.

  Unfortunaly one of the real problematic commits was right at the
  beginning, so I rebased this portion of the pending patches without
  the offenders.

  It would be great to get this into 3.19.  That makes reworking the
  problematic parts simpler.  The usual tip testing did not unearth any
  issues and it is fully bisectible now.

  I'm pretty confident that this wont affect the calmness of the xmas
  season.

  Changes:
   - Split the convoluted io_apic.c code into domain specific parts
     (vector, ioapic, msi, htirq)
   - Introduce proper helper functions to retrieve irq specific data
     instead of open coded dereferencing of pointers

PM: Eliminate CONFIG_PM_RUNTIME

Having switched over all of the users of CONFIG_PM_RUNTIME to use
CONFIG_PM directly, turn the latter into a user-selectable option
and drop the former entirely from the tree.
