== SRU Justification ==
A regression was introduced by mainline commit c950fd6f201a.  Because of this 
regression, Pstore dump for powerpc is broken.  On panic, kernel doesn't 
write mesg to /fs/pstore/dmesg*

This fix is specific to powerpc and has been cc'd to upstream stable.  It
is alredy in Artful master-next.  This commit was included in mainline as 
of v4.12-rc1.

== Fix ==
commit 041939c1ec54208b42f5cd819209173d52a29d34

    pstore: Fix flags to enable dumps on powerpc

== Regression Potential ==
This fix is specific to powerpc, so the risk of regression is very low for 
other arches.  It was also cc'd to stable to fix a known regression. 

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