Merge remote-tracking branch 'remotes/dgibson/tags/ppc-for-4.1-20190529' into staging

ppc patch queue 2019-05-29

Next pull request against qemu-4.1.  Highlights:
  * KVM accelerated support for the XIVE interrupt controller in PAPR
    guests
  * A number of TCG vector fixes
  * Fixes for the PReP / 40p machine
  * Improvements to make check-tcg test coverage

Other than that it's just a bunch of assorted fixes, cleanups and
minor improvements.

This supersedes both the pull request dated 2019-05-21 and the one
dated 2019-05-22.  I've dropped one hunk which I think may have caused
the check-tcg failure that Peter saw (by enabling the ppc64abi32
build, which I think has been broken for ages).  I'm not entirely
certain, since I haven't reproduced exactly the same failure.
