Merge tag 'asm-generic-4.6' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic

Pull asm-generic syscall fix from Arnd Bergmann:
 "My last pull request for asm-generic had just one patch that added two
  new system calls to asm/unistd.h, but unfortunately it turned out to
  be wrong, pointing arch/tile compat mode at the native handlers rather
  than the compat ones.

  This was spotted by Yury Norov, who is working on ILP32 mode for
  arch/arm64, which would have the same problem when merged.  This fixes
  the table to use the correct compat syscalls, like the other 64-bit
  architectures do.

  I'll try to find the time to come up with a solution that prevents
  this problem from happening again, by allowing all future system calls
  to just get added in a single file for use by all architectures"
