Merge branch 'merge' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpcHEADmaster

Pull powerpc fixes from Ben Herrenschmidt:
 "Here are a few powerpc bits & fixes for rc1.  A couple of str*cpy
  fixes, some fixes in handling the FSCR register on Power8 (controls
  the enabling of processor features), a 32-bit build fix and a couple
  more nits."

* 'merge' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc:
  powerpc: Set DSCR bit in FSCR setup
  powerpc: Add DSCR FSCR register bit definition
  powerpc: Fix setting FSCR for HV=0 and on secondary CPUs
  powerpc: Wireup the kcmp syscall to sys_ni
  powerpc: Remove unused BITOP_LE_SWIZZLE macro
  powerpc: Avoid link stack corruption in MMU on syscall entry path
  drivers/tty/hvc: Use strlcpy instead of strncpy
  powerpc/pseries/hvcserver: Fix strncpy buffer limit in location code
  powerpc: Fix compile of sha1-powerpc-asm.S on 32-bit
