Assorted accumulated patches.  These are nearly all bugfixes at one
 level or another - some for longstanding problems, others for some
 regressions caused by more recent cleanups.
 
 This includes preliminary patches towards fixing migration for Radix
 Page Table guests under POWER9 and also fixing some migration
 regressions due to the re-organization of the interrupt controller
 code.  Not all the pieces are there yet, so those still won't quite
 work, but the preliminary changes make sense on their own.
