Archer Yan 8df0d57e5c MIPS: Fix kernel crash for R6 in jump label branch function 
commit 47c25036b60f27b86ab44b66a8861bcf81cde39b upstream.

Insert Branch instruction instead of NOP to make sure assembler don't
patch code in forbidden slot. In jump label function, it might
be possible to patch Control Transfer Instructions(CTIs) into
forbidden slot, which will generate Reserved Instruction exception
in MIPS release 6.

  - Add MIPS prefix to subject.
  - Mark for stable from v4.0, which introduced r6 support, onwards.]
