  spapr/xive: Fix migration of hot-plugged CPUs (2019-08-13 16:50:30 +1000)

----------------------------------------------------------------
ppc patch queue 2019-08-13 (last minute qemu-4.1 fixes)

Here's a very, very last minute pull request for qemu-4.1.  This fixes
two nasty bugs with the XIVE interrupt controller in "dual" mode
(where the guest decides which interrupt controller it wants to use).
One occurs when resetting the guest while I/O is active, and the other
with migration of hotplugged CPUs.

The timing here is very unfortunate.  Alas, we only spotted these bugs
very late, and I was sick last week, delaying analysis and fix even
further.

This series hasn't had nearly as much testing as I'd really like, but
I'd still like to squeeze it into qemu-4.1 if possible, since
definitely fixing two bad bugs seems like an acceptable tradeoff for
the risk of introducing different bugs.
