This is substantially more than just the build change that the changelog
would seem to indicate...  it would I think be clearer to split this up
further with the code changes separated out and explained a bit more.
It's not just recompling the code for nVHE, there's also refactoring to
split out changes that don't apply in nVHE hypervisor like all the task
related code which is needed but not mentioned in the changlog at all.
Possibly a patch or two for the code motion then a separate patch for
the ifdefs and build changes?

I *think* the code is all fine but I'd need to go through it a few more
times to be sure I didn't miss anything.
