  MIPS: Fix build with binutils 2.24.51+ (2014-11-07 15:07:36 +0100)

This weeks' round of MIPS bug fixes for 3.18:

 o Wire up the bpf syscall
 o Fix TLB dump output for R3000 class TLBs
 o Fix strnlen_user return value if no NUL character was found.
 o Fix build with binutils 2.24.51+.  While there is no binutils 2.25
   release yet, toolchains derived from binutils 2.24.51+ are already in
   common use.
 o The Octeon GPIO code forgot to offline GPIO IRQs.
 o Fix build error for XLP.
 o Fix possible BUG assertion with EVA for CMA

  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.

Hi, Ralf,

It seems like this patch is missing during rebase:

I didn't rebase - I think I may have fallen victim to a stg bug a few days
ago.  Several other commits also got dropped as by the same incident.  I've
resurrected them but that's for another pull request.

 - Fix invalid initialization on S-cache-less systems.
 - Fix possible information leak from the kernel stack for SIGFPE.
 - Fix handling of copy_{from,to}_user() return value in KVM
