x86/microcode/intel: Simplify update_match_cpu()

2015-05-18T07:32:36+00:00

Drop unreadable macro, deconstruct compound conditional
statement into single ones and return early if they match. Add
comments.

There should be no functionality change resulting from this
patch.

x86/microcode/intel: Rename get_matching_microcode

2015-05-18T07:32:36+00:00

... to has_newer_microcode() as it does exactly that: checks
whether binary data @mc has newer microcode patch than the
applied one. Move @mc to be the first function arg too.

x86/microcode/intel: Get rid of revision_is_newer()

2015-05-06T09:24:44+00:00

It is a one-liner for checking microcode header revisions. On top of
that, it can be used wrong as it was the case in _save_mc(). Get rid of
it.

x86/microcode/intel: Move mc arg last in get_matching_{microcode|sig}

2015-03-02T19:32:13+00:00

... arguments list so that it comes more natural for those functions to
have the signature, processor flags and revision together, before the
rest of the args.

No functionality change.

x86, microcode: Move to a proper location

2014-01-13T19:00:12+00:00

We've grown a bunch of microcode loader files all prefixed with
"microcode_". They should be under cpu/ because this is strictly
CPU-related functionality so do that and drop the prefix since they're
in their own directory now which gives that prefix. :)

While at it, drop MICROCODE_INTEL_LIB config item and stash the
functionality under CONFIG_MICROCODE_INTEL as it was its only user.
