Pull MIPS fixes from Ralf Baechle:
 "Two platform-specific fixes plus a fix for oprofile which was calling
  smp_processor_id() in preemptible code"

* 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus:
  MIPS: BMIPS: fix hardware interrupt routing for boot CPU != 0
  MIPS: oprofile: Fix BUG due to smp_processor_id() in preemptible code.
  MIPS: PNX833x: PNX8335_PCI_ETHERNET_INT depends on CONFIG_SOC_PNX8335
