[Bionic][PATCH 0/3] Fixes for LP:1758206

[Joseph Salisbury]

BugLink: http://bugs.launchpad.net/bugs/1758206

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

The three commits requested have been tested in a test kernel and shown to resolve this bug.  The 
first two commits are in mailine as of v4.16-rc1 and the third is in v4.16-rc2.
