Pull powerpc fixes from Michael Ellerman:
 "Ben's travelling so this is my first attempt at a pull request.

  There's nothing too exciting.  The CONFIG_FHANDLE one is annoying, I
  know you love defconfig changes.  But we've had a couple of developers
  waste time debugging boxes that wouldn't boot, only to realise it's
  just that systemd needs CONFIG_FHANDLE and our defconfigs don't have
  it.

  The new syscalls seem to be working, I've run the selftests that
  exist, and also let trinity bash on them for a while"

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mpe/linux:
  powerpc: Wire up sys_seccomp(), sys_getrandom() and sys_memfd_create()
  powerpc: Make CONFIG_FHANDLE=y for all 64 bit powerpc defconfigs
  powerpc: use machine_subsys_initcall() for opal_hmi_handler_init()
  powerpc/perf: Fix ABIv2 kernel backtraces
  powerpc/pseries: Fix endian issues in memory hotplug
