Merge commit '5bc66170dc486556a1e36fd384463536573f4b82' into x86/urgent
From Borislav Petkov <bp@amd64.org>:
Below is a RAS fix which reverts the addition of a sysfs attribute
which we agreed is not needed, post-factum. And this should go in now
because that sysfs attribute is going to end up in 3.7 otherwise and
thus exposed to userspace; removing it then would be a lot harder.
This is done as a merge rather than a simple patch/cherry-pick since
the baseline for this patch was not in the previous x86/urgent.
