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

Pull MIPS update from Ralf Baechle:
 "This is the MIPS update for 3.7.

  A fair chunk of them are platform updates to the Cavium Octeon SOC
  (which involves machine generated header files of considerable size),
  Atheros ATH79xx, RMI aka Netlogic aka Broadcom XLP, Broadcom BCM63xx
  platforms.

  Support for the commercial MIPS simulator MIPSsim has been removed as
  MIPS Technologies is shifting away from this product and Qemu is
  offering various more powerful platforms.  The generic MIPS code can
  now also probe for no-execute / write-only TLB features implemented
  without the full SmartMIPS extension as permitted by the latest MIPS
  processor architecture.  Lots of small changes to generic code."

* 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus: (78 commits)
  MIPS: ath79: Fix CPU/DDR frequency calculation for SRIF PLLs
  MIPS: ath79: use correct fractional dividers for {CPU,DDR}_PLL on AR934x
  MIPS: BCM63XX: Properly handle mac address octet overflow
  MIPS: Kconfig: Avoid build errors by hiding USE_OF from the user.
  MIPS: Replace `-' in defconfig filename wth `_' for consistency.
  MIPS: Wire kcmp syscall.
  MIPS: MIPSsim: Remove the MIPSsim platform.
  MIPS: NOTIFY_RESUME is not needed in TIF masks
  MIPS: Merge the identical "return from syscall" per-ABI code
  MIPS: Unobfuscate _TIF..._MASK
  MIPS: Prevent hitting do_notify_resume() with !user_mode(regs).
  MIPS: Replace 'kernel_uses_smartmips_rixi' with 'cpu_has_rixi'.
  MIPS: Add base architecture support for RI and XI.
  MIPS: Optimise TLB handlers for MIPS32/64 R2 cores.
  MIPS: uasm: Add INS and EXT instructions.
  MIPS: Avoid pipeline stalls on some MIPS32R2 cores.
  MIPS: Make VPE count to be one-based.
  MIPS: Add new end of interrupt functionality for GIC.
  MIPS: Add EIC support for GIC.
  MIPS: Code clean-ups for the GIC.
