[SRU][Artful][PATCH 0/3] Fixes for LP:1776211

[Joseph Salisbury]

BugLink: http://bugs.launchpad.net/bugs/1776211

== SRU Justification ==
IBM has requested these three commits in Artful.  In Artful, kdump fails to
capture dump when smt=2 or off.

Including these three commits allows kdump to work properly.

== Fixes ==
4388c9b3a6ee ("powerpc: Do not send system reset request through the oops path")
04b9c96eae72 ("powerpc/crash: Remove the test for cpu_online in the IPI callback")
4552d128c26e ("powerpc: System reset avoid interleaving oops using die synchronisation")

== Regression Potential ==
Low.  Fixes are limited to powerpc.

== Test Case ==
A test kernel was built with these patches and tested by the original bug reporter.
The bug reporter states the test kernel resolved the bug.

Balbir Singh (1):
  powerpc/crash: Remove the test for cpu_online in the IPI callback

Nicholas Piggin (2):
  powerpc: Do not send system reset request through the oops path
  powerpc: System reset avoid interleaving oops using die
    synchronisation
