ppc patch queue 2018-03-06

Browse Source 
This pull request supersedes ppc-for-2.12-20180302 which had compile
 problems with some gcc versions.  It also contains a few additional
 patches.
 
 Highlights are:
     * New Sam460ex machine type
     * Yet more fixes related to vcpu id allocation for spapr
     * Numerous macio cleanupsr
     * Some enhancements to the Spectre/Meltdown fixes for pseries,
       allowing use of a better mitigation for indirect branch based
       exploits
     * New pseries machine types with Spectre/Meltdown mitigations
       enabled (stop gap until libvirt and management understands the
       machine options)
     * A handful of other fixes
