My tests were x86-only, for both guest and host:

^^^^^^^
Sorry for not being clearer.
I have not tested the ARM bits. I just tested aarch64 and it works, though.
I put the scripts online so that others can easily generate natively the ck_pr
tests. If you have an architecture I don't have access to (e.g. ARM, Alpha),
please send me the resulting tarball (the ck_pr.sh script takes care of
everything)
and I'll upload it with the others:
