Pull more powerpc updates from Michael Ellerman:
 "Here's some more updates for powerpc for 3.18.

  They are a bit late I know, though must are actually bug fixes.  In my
  defence I nearly cut the top of my finger off last weekend in a
  gruesome bike maintenance accident, so I spent a good part of the week
  waiting around for doctors.  True story, I can send photos if you like :)

  Probably the most interesting fix is the sys_call_table one, which
  enables syscall tracing for powerpc.  There's a fix for HMI handling
  for old firmware, more endian fixes for firmware interfaces, more EEH
  fixes, Anton fixed our routine that gets the current stack pointer,
  and a few other misc bits"

  powerpc: sync pseries_le_defconfig with pseries_defconfig
  powerpc: Add printk levels to setup_system output
  powerpc/vphn: NUMA node code expects big-endian
  powerpc/msi: Use WARN_ON() in msi bitmap selftests
  powerpc/msi: Fix the msi bitmap alignment tests
  powerpc/eeh: Block CFG upon frozen Shiner adapter
  powerpc/eeh: Don't collect logs on PE with blocked config space
