From bc4e0f9ae2b1b133d36c1392d0145d2997cff272 Mon Sep 17 00:00:00 2001 From: Ben Castricum Date: Tue, 10 Jun 2008 13:15:12 +0200 Subject: [PATCH] x86: microcode: cosmetic changes First announce ourself, then start working. Currently this module reports itself when all is completed which is not most modules do. Plus some cosmetic/whitespace cleanups.
