Pull MIPS updates from Ralf Baechle:
 - Support for Imgtec's Aptiv family of MIPS cores.
 - Improved detection of BCM47xx configurations.
 - Fix hiberation for certain configurations.
 - Add support for the Chinese Loongson 3 CPU, a MIPS64 R2 core and
   systems.
 - Detection and support for the MIPS P5600 core.
 - A few more random fixes that didn't make 3.14.
 - Support for the EVA Extended Virtual Addressing
 - Switch Alchemy to the platform PATA driver
 - Complete unification of Alchemy support
 - Allow availability of I/O cache coherency to be runtime detected
 - Improvments to multiprocessing support for Imgtec platforms
 - A few microoptimizations
 - Cleanups of FPU support
 - Paul Gortmaker's fixes for the init stuff
 - Support for seccomp
