* 'upstream' of git://ftp.linux-mips.org/pub/scm/upstream-linus:
  [MIPS] MTX1: clear PCI errors
  [MIPS] MTX1: add idsel cardbus ressources
  [MIPS] MTX1: remove unneeded settings
  [MIPS] dma_sync_sg_for_cpu is a no-op except for non-coherent R10000s.
  [MIPS] Cobalt: update reserved resources
  [MIPS] SN: PCI fixup needs to include <irq.h>.
  [MIPS] DMA: Fix a bunch of warnings due to missing inline keywords.
  [MIPS] RM: It should be #ifdef CONFIG_FOO not #if CONFIG_FOO ...
  [MIPS] Fix and cleanup the mess that a dozen prom_printf variants are.
  [MIPS] DEC: Remove redeclarations of mips_machgroup and mips_machtype.
  [MIPS] No need to write c0_compare in plat_timer_setup
  [MIPS] Convert to RTC-class ds1742 driver
  [MIPS] Oprofile: Add missing break statements.
  [MIPS] jmr3927: build fix
  [MIPS] SNI: Fix mc146818_decode_year
  [MIPS] Replace sys32_timer_create with the generic compat_sys_timer_create.
  [MIPS] Replace sys32_socketcall with the generic compat_sys_socketcall.
  [MIPS] N32 waitid is the same as o32.
