MIPS changes for 4.18 

These are the main MIPS changes for 4.18. Rough overview:
 
  (1) MAINTAINERS: Add Paul Burton as MIPS co-maintainer
 
  (2) Misc: Generic compiler intrinsics, Y2038 improvements, Perf+MT fixes
 
  (3) Platform support: Netgear WNR1000 V3, Microsemi Ocelot integrated
      switch, Ingenic watchdog cleanups
 
 Maintainers:
 
  - Add Paul Burton as MIPS co-maintainer
 
 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

 "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()
