Merge branch 'upstream' of git://ftp.linux-mips.org/pub/scm/upstream-linus 

* 'upstream' of git://ftp.linux-mips.org/pub/scm/upstream-linus:
  [MIPS] SMTC: Fix recursion in instant IPI replay code.
  [MIPS] BCM1480: Fix setting of irq affinity.
  [MIPS] do_page_fault() needs to use raw_smp_processor_id().
  [MIPS] SMTC: Fix false trigger of debug code on single VPE.
  [MIPS] SMTC: irq_{enter,leave} and kstats keeping for relayed timer ints.
  [MIPS] lockdep: Deal with interrupt disable hazard in TRACE_IRQFLAGS
  [MIPS] lockdep: Handle interrupts in R3000 style c0_status register.
  [MIPS] MV64340: Add missing prototype for mv64340_irq_init().
  [MIPS] MT: MIPS_MT_SMTC_INSTANT_REPLAY currently conflicts with PREEMPT.
  [MIPS] EV64120: Include <asm/irq.h> to fix warning.
  [MIPS] Ocelot: Fix warning.
  [MIPS] Ocelot: Give PMON_v1_setup a proper prototype.
