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

Pull MIPS fixes from Ralf Baechle:
 "Pretty much all across the field so with this we should be in
  reasonable shape for the upcoming -rc2"

* 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus:
  MIPS: OCTEON: make get_system_type() thread-safe
  MIPS: CPS: Initialize EVA before bringing up VPEs from secondary cores
  MIPS: Malta: EVA: Rename 'eva_entry' to 'platform_eva_init'
  MIPS: EVA: Add new EVA header
  MIPS: scall64-o32: Fix indirect syscall detection
  MIPS: syscall: Fix AUDIT value for O32 processes on MIPS64
  MIPS: Loongson: Fix COP2 usage for preemptible kernel
  MIPS: NL: Fix nlm_xlp_defconfig build error
  MIPS: Remove race window in page fault handling
  MIPS: Malta: Improve system memory detection for '{e, }memsize' >= 2G
  MIPS: Alchemy: Fix db1200 PSC clock enablement
  MIPS: BCM47XX: Fix reboot problem on BCM4705/BCM4785
  MIPS: Remove duplicated include from numa.c
  MIPS: Add common plat_irq_dispatch declaration
  MIPS: MSP71xx: remove unused plat_irq_dispatch() argument
  MIPS: GIC: Remove useless parens from GICBIS().
  MIPS: perf: Mark pmu interupt IRQF_NO_THREAD
