Revision e6a588d086a75dc20afb8ffbcbe23a50d4a1ca37 authored by Linus Torvalds on 22 November 2014, 00:14:58 UTC, committed by Linus Torvalds on 22 November 2014, 00:14:58 UTC 
Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus
 
Pull MIPS fixes from Ralf Baechle:
 "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"

  MIPS: jump_label.c: Handle the microMIPS J instruction encoding
  MIPS: jump_label.c: Correct the span of the J instruction
  MIPS: Zero variable read by get_user / __get_user in case of an error.
  MIPS: lib: memcpy: Restore NOP on delay slot before returning to caller
  MIPS: tlb-r4k: Add missing HTW stop/start sequences
  MIPS: asm: uaccess: Add v1 register to clobber list on EVA
  MIPS: oprofile: Fix backtrace on 64-bit kernel
  MIPS: Loongson: Set Loongson-3's ISA level to MIPS64R1
