So this function is there in cpu/common.c because it uses CPU facilities
like cpuinfo_x86 and get_cpu_cap() so the logical place was there.
So that I don't have to export a bunch of things but rather have the
microcode loader call into it only.
Your next patch is using more of those CPU-specific facilities so
"bleeding" them into the microcode loader looks like the wrong way
around.
get_cpu_cap() deals with all those c->x86_capability arrays and other
functions which do that, should be there too.
