Merge master.kernel.org:/pub/scm/linux/kernel/git/davem/sparc-2.6
* 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()

/* To avoid some locking problems, we hard allocate certain PILs

- * A cli() does not block the cross call delivery, so when SMP
