while I absolutely don't disagree with what you say, breaking existing
userspace is not an option.
Yes I very much would like for microcode_ctl to die as well (in fact,
that was one of the reasons we had the microcode code use
request_firmware), but that doesn't mean we can just ditch
compatibility ;(
