Subject: [PATCH 0/5] x86/CPU: Improve AMD Erratum 400 workaround

From: Borislav Petkov <bp@...e.de>

Hi,

here's the final version of the pile we've been working on for a while
now, trying to remove that rdmsr on the idle path.

@jolsa: just wait until it lands in tip and then you can run it on your
box.

Thanks.
