2016-03-08T08:08:44+00:00

sizeof(u32) is perfectly clear as it is.

x86/microcode: Merge the early microcode loader

2015-10-21T09:22:12+00:00

Merge the early loader functionality into the driver proper. The
diff is huge but logically, it is simply moving code from the
_early.c files into the main driver.

x86/microcode/intel: Rename get_matching_sig()

2015-05-18T07:32:37+00:00

... to find_matching_signature() which is exactly what it does.

No functionality change.

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.

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.

have the signature, processor flags and revision together, before the
rest of the args.

x86, microcode: Reload microcode on resume

2014-12-06T12:03:03+00:00

Normally, we do reapply microcode on resume. However, in the cases where
that microcode comes from the early loader and the late loader hasn't
been utilized yet, there's no easy way for us to go and apply the patch
applied during boot by the early loader.

Thus, reuse the patch stashed by the early loader for the BSP.
