* master.kernel.org:/pub/scm/linux/kernel/git/davem/sparc-2.6:
  [SPARC64]: Update defconfig.
  [VIDEO]: XVR-500 and XVR-2500 need FB=y.
  [SPARC32]: asm/system.h needs asm/smp.h
  [SPARC32]: Update defconfig.
  [SPARC32]: Fix sparc32 kdebug changes.
  [SPARC64]: Accept ebus_bus_type for generic DMA ops.
  [SPARC64]: Add missing cpus_empty() check in hypervisor xcall handling.
  [SCSI]: Add help text for SCSI_ESP_CORE.
  [SPARC] SBUS: display7seg.c needs asm/io.h
  [SPARC] SBUS: bbc_i2c.c needs asm/io.h
  [SPARC64]: Be more resiliant with PCI I/O space regs.
  [SERIAL] SUNHV: Add an ID string.
