  docs: provide documentation on the POWER9 XIVE interrupt controller 
(2019-05-22 10:38:22 +1000)

----------------------------------------------------------------
ppc patch queue 2019-05-22

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

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

This supersedes the pull request dated 2019-05-21.  I've dropped the
headers update, since it had a mistake, but is now made redundant by a
similar update in Cornelia's applied PR.  I've also added a patch with
extra documentation for the XIVE interrupt controller, and fixed a
couple of minor style errors in the previous PR.
