  MIPS: jump_label.c: Handle the microMIPS J instruction encoding (2014-11-19 18:22:09 +0100)

More 3.18 fixes for MIPS:

 - Backtraces were not quite working on on 64-bit kernels
 - Loongson needs a different cache coherency setting
 - Loongson 3 is a MIPS64 R2 version but due to erratum we treat is an
   older architecture revision.
 - Fix build errors due to undefined references to __node_distances for
   certain configurations.
 - Fix instruction decodig in the jump label code.
 - For certain configurations copy_{from,to}_user destroy the content
   of $3 so that register needs to be marked as clobbed by the calling
   code.
 - Hardware Table Walker fixes.
 - Fill the delay slot of the last instruction of memcpy otherwise
   whatever ends up there randomly might have undesirable effects.
 - Ensure get_user/__get_user always zero the variable to be read even
   in case of an error.

Please consider pulling,

  Ralf
