Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus
Pull MIPS updates from Ralf Baechle:
"This is the MIPS pull request for the next kernel:
- Zubair's patch series adds CMA support for MIPS. Doing so it also
touches ARM64 and x86.
- remove the last instance of IRQF_DISABLED from arch/mips
- updates to two of the MIPS defconfig files.
- cleanup of how cache coherency bits are handled on MIPS and
implement support for write-combining.
- platform upgrades for Alchemy
- move MIPS DTS files to arch/mips/boot/dts/"
