Merge branch 'irq-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

2013-11-19T18:40:00+00:00

Pull irq cleanups from Ingo Molnar:
 "This is a multi-arch cleanup series from Thomas Gleixner, which we
  kept to near the end of the merge window, to not interfere with
  architecture updates.

  This series (motivated by the -rt kernel) unifies more aspects of IRQ
  handling and generalizes PREEMPT_ACTIVE"

* 'irq-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  preempt: Make PREEMPT_ACTIVE generic
  sparc: Use preempt_schedule_irq
  ia64: Use preempt_schedule_irq
  m32r: Use preempt_schedule_irq
  hardirq: Make hardirq bits generic

kernel: remove CONFIG_USE_GENERIC_SMP_HELPERS

2013-11-15T00:32:22+00:00

We've switched over every architecture that supports SMP to it, so
remove the new useless config variable.

mm: use pgdat_end_pfn() to simplify the code in arch

2013-11-13T03:09:03+00:00

Use "pgdat_end_pfn()" instead of "pgdat->node_start_pfn +
pgdat->node_spanned_pages".  Simplify the code, no functional change.

mm/arch: use __free_reserved_page() to simplify the code

2013-11-13T03:09:03+00:00

Use __free_reserved_page() to simplify the code in arch.

It used split_page() in consistent_alloc()/__dma_alloc_coherent()/dma_alloc_coherent(),
so page->_count == 1, and we can free it safely.

__free_reserved_page()
	ClearPageReserved()
	init_page_count()  // it won't change the value
	__free_page()

Pull devicetree updates from Rob Herring:
"DeviceTree updates for 3.13. This is a bit larger pull request than
usual for this cycle with lots of clean-up.

- Cross arch clean-up and consolidation of early DT scanning code.
- Clean-up and removal of arch prom.h headers. Makes arch specific
prom.h optional on all but Sparc.
- Addition of interrupts-extended property for devices connected to
multiple interrupt controllers.
- Refactoring of DT interrupt parsing code in preparation for
deferred probe of interrupts.
- ARM cpu and cpu topology bindings documentation.
- Various DT vendor binding documentation updates"

2013-11-12T05:25:33+00:00

Pull metag architecture changes from James Hogan:
 - A change to remove the last dependence on bootloader exception
   handlers so that QEMU can more easily boot an SMP Linux/Meta kernel
   image directly.
 - A fix for a minor off by one error in a BUG_ON condition found by Dan
   Carpenter.
