For consistency, should this feature be renamed AMD_PSFD, now that Intel is enumerating PSFD with CPUID.(EAX=7,ECX=2):EDX.PSFD[bit 0]? Seehttps://www.intel.com/content/www/us/en/developer/articles/technical/software-security-guidance/technical-documentation/cpuid-enumeration-and-architectural-msrs.html. And, Paolo, why are we carrying X86_FEATURE_PSFD as a private #define in KVM rather than putting it where it belongs in cpufeatures.h?
Borislav asked to not show psfd in /proc/cpuinfo, because Linux had decided not to control PSF separately; instead it just piggybacked on SSBD which should disable PSF as well. Honestly I disagree but it's not my area of maintenance. Paolo
