Subject: [PATCH 0/9 v3] New way to track mce notifier chain actions

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

Hi all,

here's what I have. I'd like to keep mce.kflags hidden for now.

The last patch is something tglx spotted yesterday and fixing that with
the MCE flags is pretty easy - was boxing with a wrapper struct around
struct mce and that gets really ugly.

Tony, I'm open to suggestions how to test it - I probably don't have an
access to such box which can trigger read errors on nvdimms or what was
the use case?

Thx.
