Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus

Pull MIPS fixes from Ralf Baechle:
 "Here's the first round of MIPS fixes after the merge window:

   - Detect Octeon III's PCI correctly.
   - Fix return value of the MT7620 probing function.
   - Wire up the copy_file_range syscall.
   - Fix 64k page support on 32 bit kernels.
   - Fix the early Coherency Manager probe.
   - Allow only hardware-supported page sizes to be selected for R6000.
   - Fix corner cases for the RDHWR nstruction emulation on old hardware.
   - Fix FPU handling corner cases.
   - Remove stale entry for BCM33xx from the MAINTAINERS file.
   - 32 and 64 bit ELF headers are different, handle them correctly"
