Merge tag 'mips_fixes_4.16_1' of git://git.kernel.org/pub/scm/linux/kernel/git/jhogan/mips
Pull MIPS fixes from James Hogan: "A couple of MIPS fixes for 4.16-rc1, including an important regression in 4.15 and a rather more longstanding corner case build fix. These are separate from the main pull request as one of the bugs fixed was only recently introduced in v4.15-rc8. - Fix CPS regression on older binutils due to MIPS_ISA_LEVEL_RAW fix (4.15) - Fix allmodconfig + CONFIG_MACH_TX49XX=y builds due to incorrect use of IS_ENABLED() (2.6.28)" * tag 'mips_fixes_4.16_1' of git://git.kernel.org/pub/scm/linux/kernel/git/jhogan/mips: MIPS: TXx9: use IS_BUILTIN() for CONFIG_LEDS_CLASS MIPS: CPS: Fix MIPS_ISA_LEVEL_RAW fallout
