  powerpc/powernv: Properly set "host-ipi" on IPIs (2017-02-09 15:51:21 +1100)

powerpc fixes for 4.10 #4

Four fixes from Ben:

 - Userspace was semi-randomly segfaulting on radix due to us incorrectly
   handling a fault triggered by autonuma, caused by a patch we merged earlier
   in v4.10 to prevent the kernel executing userspace.
 - We weren't marking host IPIs properly for KVM in the OPAL ICP backend.
 - The ERAT flushing on radix was missing an isync and was incorrectly marked
   as DD1 only.
 - The powernv CPU hotplug code was missing a wakeup type and failing to flush
   the interrupt correctly when using OPAL ICP.

Thanks to:
  Benjamin Herrenschmidt.
