x86: microcode_amd: modify log messages
Impact: change microcode printk content Change log level and provide (at least I tried to;-) consistent, short, meaningful content. Signed-off-by: Andreas Herrmann <andreas.herrmann3@amd.com> Cc: Dmitry Adamushko <dmitry.adamushko@gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
