* 'upstream' of git://ftp.linux-mips.org/pub/scm/upstream-linus: (38 commits)
  MIPS: Sibyte: Fix locking in set_irq_affinity
  MIPS: Use force_sig when handling address errors.
  MIPS: Cavium: Add struct clocksource * argument to octeon_cvmcount_read()
  MIPS: Rewrite <asm/div64.h> to work with gcc 4.4.0.
  MIPS: Fix highmem.
  MIPS: Fix sign-extension bug in 32-bit kernel on 32-bit hardware.
  MIPS: MSP71xx: Remove the RAMROOT functions
  MIPS: Use -mno-check-zero-division
  MIPS: Set compiler options only after the compiler prefix has ben set.
  MIPS: IP27: Get rid of #ident.  Gcc 4.4.0 doesn't like it.
  MIPS: uaccess: Switch lock annotations to might_fault().
  MIPS: MSP71xx: Resolve use of non-existent GPIO routines in msp71xx reset
  MIPS: MSP71xx: Resolve multiple definition of plat_timer_setup
  MIPS: Make uaccess.h slightly more sparse friendly.
  MIPS: Make access_ok() sideeffect proof.
  MIPS: IP27: Fix clash with NMI_OFFSET from hardirq.h
  MIPS: Alchemy: Timer build fix
  MIPS: Kconfig: Delete duplicate definition of RWSEM_GENERIC_SPINLOCK.
  MIPS: Cavium: Add support for 8k and 32k page sizes.
  MIPS: TXx9: Fix possible overflow in clock calculations
