* git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc-next-2.6: (28 commits)
  sparc32: fix build, fix missing cpu_relax declaration
  SCHED_TTWU_QUEUE is not longer needed since sparc32 now implements IPI
  sparc32,leon: Remove unnecessary page_address calls in LEON DMA API.
  sparc: convert old cpumask API into new one
  sparc32, sun4d: Implemented SMP IPIs support for SUN4D machines
  sparc32, sun4m: Implemented SMP IPIs support for SUN4M machines
  sparc32,leon: Implemented SMP IPIs for LEON CPU
  sparc32: implement SMP IPIs using the generic functions
  sparc32,leon: SMP power down implementation
  sparc32,leon: added some SMP comments
  sparc: add {read,write}*_be routines
  sparc32,leon: don't rely on bootloader to mask IRQs
  sparc32,leon: operate on boot-cpu IRQ controller registers
  sparc32: always define boot_cpu_id
  sparc32: removed unused code, implemented by generic code
  sparc32: avoid build warning at mm/percpu.c:1647
  sparc32: always register a PROM based early console
  sparc32: probe for cpu info only during startup
  sparc: consolidate show_cpuinfo in cpu.c
  sparc32,leon: implement genirq CPU affinity
