Overall, the series looks better. I've pointed out a few things that
need changing, but my overall gripe is around the abuse the
stacktrace/nvhe.h as a dumping ground. A lot of the code there could
be pushed to handle_exit.c (or some other compilation unit).

I've pushed an example of a 10 minutes refactor in my tree
(kvm-arm64/nvhe-stacktrace), and I'm sure these are the lowest hanging
fruits.

Thanks,

	M.
