  powerpc/64: Initialise thread_info for emergency stacks (2017-06-23 13:25:38 +1000)

----------------------------------------------------------------
powerpc fixes for 4.12 #7

 - three fixes for kprobes/ftrace/livepatch interactions.

 - properly handle data breakpoints when using the Radix MMU.

 - fix for perf sampling of registers during call_usermodehelper().

 - properly initialise the thread_info on our emergency stacks.

 - add an explicit flush when doing TLB invalidations for a process
   using NPU2.

Thanks to:
  Alistair Popple, Naveen N. Rao, Nicholas Piggin, Ravi Bangoria,
  Masami Hiramatsu.
