This patch series provides a generic helper function, prot_guest_has(),
to replace the sme_active(), sev_active(), sev_es_active() and
mem_encrypt_active() functions.

It is expected that as new protected virtualization technologies are
added to the kernel, they can all be covered by a single function call
instead of a collection of specific function calls all called from the
same locations.

The powerpc and s390 patches have been compile tested only. Can the
folks copied on this series verify that nothing breaks for them.

There are some patches related to PPC that added new calls to the 
mem_encrypt_active() function that are not yet in the tip tree. After the 
merge window, I'll need to send a v3 with those additional changes before 
this series can be applied.

Thanks,
Tom
