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

Pull mips fixes from Ralf Baechle:
 "The hopefully final round of fixes for 3.18:

   - Fix a number of build errors affecting particular configurations.
   - Handle EVA correctly when flushing a signal trampoline and dcache
     lines.
   - Fix printks printing jibberish.
   - Handle 64 bit memory addresses correctly when adding memory chunk
     on 32 bit kernels.
   - Fix a race condition in the hardware tablewalker code"

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