Leftovers from the earlier patchset rediffed to 2.6.33-rc2.
Mostly applications of per cpu counters to core components and cleanup patches.

After this patchset there will be only one user of local_t left: Mathieu's
trace ringbuffer.

V8->V9
- Split patches for the module logic differently.
- Fix spurious free in module patch.
- Drop ringbuffer stuff. Needs more discussion.
- Drop slub patches (already in Pekka's tree and in -next)
- Add SPARC cleanup patch.

V7->V8
- Fix issue in slub patch
- Fix issue in modules patch
- Rediff page allocator patch
- Provide new this_cpu ops needed for ringbuffer [RFC state]

V6->V7
- Drop patches merged in 2.6.33 merge cycle
- Drop risky slub patches

V5->V6:
- Drop patches merged by Tejun.
- Drop irqless slub fastpath for now.
- Patches against Tejun percpu for-next branch.

V4->V5:
- Avoid setup_per_cpu_area() modifications and fold the remainder of the
  patch into the page allocator patch.
- Irq disable / per cpu ptr fixes for page allocator patch.

V3->V4:
- Fix various macro definitions.
- Provide experimental percpu based fastpath that does not disable
  interrupts for SLUB.

V2->V3:
- Available via git tree against latest upstream from
	 git://git.kernel.org/pub/scm/linux/kernel/git/christoph/percpu.git linus
- Rework SLUB per cpu operations. Get rid of dynamic DMA slab creation
  for CONFIG_ZONE_DMA
- Create fallback framework so that 64 bit ops on 32 bit platforms
  can fallback to the use of preempt or interrupt disable. 64 bit
  platforms can use 64 bit atomic per cpu ops.

V1->V2:
- Various minor fixes
- Add SLUB conversion
- Add Page allocator conversion
- Patch against the git tree of today
