Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc-next-2.6
* 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 ...
