[arch-general] [arch-dev-public] Changes to microcode updates

[Marko Hauptvogel]

Referring to the comments from october 16th on the ck kernel package
page [0] and the config of said package [1], your version of the ck
kernel has not yet been configured to do early microcode updates. But
this should follow be fixed soon as the v20140913 microcode package hit
[extra] today. Try to boot the stock kernel and you should see 'updated
early' lines in your logs.

Greetings
