Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus
Pull MIPS updates from Ralf Baechle:
"These are the highlists of the main MIPS pull request for 4.4:
- Add latencytop support
- Support appended DTBs
- VDSO support and initially use it for gettimeofday.
- Drop the .MIPS.abiflags and ELF NOTE sections from vmlinux
- Support for the 5KE, an internal test core.
- Switch all MIPS platfroms to libata drivers.
- Improved support, cleanups for ralink and Lantiq platforms.
- Support for the new xilfpga platform.
- A number of DTB improvments for BMIPS.
- Improved support for CM and CPS.
- Minor JZ4740 and BCM47xx enhancements"
