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
