Merge tag 'mips_fixes_4.15_2' of git://git.kernel.org/pub/scm/linux/kernel/git/jhogan/mips 

Pull MIPS fixes from James Hogan:
 "Some final MIPS fixes for 4.15, including important build fixes and a
  MAINTAINERS update:

   - Add myself as MIPS co-maintainer.

   - Fix various all*config build failures (particularly as a result of
     switching the default MIPS platform to the "generic" platform).

   - Fix GCC7 build failures (duplicate const and questionable calls to
     missing __multi3 intrinsic on mips64r6).

   - Fix warnings when CPU Idle is enabled (4.14).

   - Fix AR7 serial output (since 3.17).

   - Fix ralink platform_get_irq error checking (since 3.12)"
