So tglx persuaded me yesterday that we should do code sharing after
all, so that all blob loading remains consistent. So let's try the
cpu/intel.c thing and see what breaks, how and when.

As to patch 8, that metadata checking should not be part of
microcode_intel_sanity_check() but a separate function. Along with
microcode_intel_find_meta_data() - all those should go into the IFS
thing.

When microcode loading ends up really needing metadata, *then*
that functionality should be lifted into a more fitting place like
cpu/intel.c

Thx.
