Subject: Re: [PATCH v2] x86/mm/cpa: Warn if set_memory_XXcrypted() fails

I can fix this up when it gets applied, but a nit about the subject:
This isn't handling generic "set_memory_XXcrypted()" failures.  It's
specifically about presumed VMM-specific failures, thus the "vmm_fail"
label and the warning text.
