* master.kernel.org:/pub/scm/linux/kernel/git/davem/sparc-2.6: [SPARC64]: Update defconfig. [SPARC64]: Don't double-export synchronize_irq. [SPARC64]: Move over to GENERIC_HARDIRQS. [SPARC64]: Virtualize IRQ numbers. [SPARC64]: Kill ino_bucket->pil [SPARC]: Kill __irq_itoa(). [SPARC64]: bp->pil can never be zero [SPARC64]: Send all device interrupts via one PIL. [SPARC]: Fix iommu_flush_iotlb end address [SPARC]: Mark smp init functions as cpuinit [SPARC]: Add missing rw can_lock macros [SPARC]: Setup cpu_possible_map [SPARC]: Add topology_init()
