Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus
Pull MIPS updates from Ralf Baechle:
- three fixes for 3.15 that didn't make it in time
- limited Octeon 3 support.
- paravirtualization support
- improvment to platform support for Netlogix SOCs.
- add support for powering down the Malta eval board in software
- add many instructions to the in-kernel microassembler.
- add support for the BPF JIT.
- minor cleanups of the BCM47xx code.
- large cleanup of math emu code resulting in significant code size
reduction, better readability of the code and more accurate
emulation.
- improvments to the MIPS CPS code.
- support C3 power status for the R4k count/compare clock device.
- improvments to the GIO support for older SGI workstations.
- increase number of supported CPUs to 256; this can be reached on
certain embedded multithreaded ccNUMA configurations.
- various small cleanups, updates and fixes
