Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus
Pull MIPS fixes from Ralf Baechle:
"MIPS fixes for various loose ends:
- Fix workarounds for R4000 erratum.
- Patch up DEC, Siemens-Nixdorf and Loongson hardware support.
- Wire up renameat2 syscall.
- Delete unused file - it was causing false warnings from maintenance
scripts.
- Revert a patch because it's functionality is now implemented twice
which causes superfluous /proc/cpuinfo output.
- Fix a microMIPS regression"
