I propose keeping either the x86 CPU capability "Memory Disambiguation"
(as you said, via the string in the define). But only for what is
displayed in /proc/cpuinfo. It seems reasonable to expect people reading
that and caring about store buffer exploits to at least have some idea
what "MD" means without having to map it to SSB directly there.
