Pull MIPS updates from James Hogan:
 "These are the main MIPS changes for 4.18.

  Rough overview:

   - MAINTAINERS: Add Paul Burton as MIPS co-maintainer

   - Misc: Generic compiler intrinsics, Y2038 improvements, Perf+MT fixes

   - Platform support: Netgear WNR1000 V3, Microsemi Ocelot integrated
     switch, Ingenic watchdog cleanups

  More detailed  summary:

  Maintainers:

   - Add Paul Burton as MIPS co-maintainer, as I soon won't have access
     to much MIPS hardware, nor enough time to properly maintain MIPS on
     my own.

  Miscellaneous:

   - Use generic GCC library routines from lib/
     - Add notrace to generic ucmpdi2 implementation
     - Rename compiler intrinsic selects to GENERIC_LIB_*
     - vmlinuz: Use generic ashldi3

   - y2038: Convert update/read_persistent_clock() to *_clock64()
     - sni: Remove read_persistent_clock()

   - perf: Fix perf with MT counting other threads
     - Probe for per-TC perf counters in cpu-probe.c
     - Use correct VPE ID for VPE tracing

  Minor cleanups:

   - Avoid unneeded built-in.a in DTS dirs

   - sc-debugfs: Re-use kstrtobool_from_user

   - memset.S: Reinstate delay slot indentation

   - VPE: Fix spelling "uneeded" -> "Unneeded"

  Platform support:

  BCM47xx:

   - Add support for Netgear WNR1000 V3

   - firmware: Support small NVRAM partitions

   - Use __initdata for LEDs platform data

  Ingenic:

   - Watchdog driver & platform code improvements:
     - Disable clock after stopping counter
     - Use devm_* functions
     - Drop module remove function
     - Move platform reset code to restart handler in driver
     - JZ4740: Convert watchdog instantiation to DT
     - JZ4780: Fix watchdog DT node
     - qi_lb60_defconfig: Enable watchdog driver

  Microsemi:

   - Ocelot: Add support for integrated switch
     - pcb123: Connect phys to ports"
