Re: Re-implement MCE log ring buffer as per-CPU ring buffer

You may also want to consider to use the in-kernel ring_buffer api
(include/linux/ring_buffer.h).

Its semantics don't map very well to the machine check requirements.

I did an analysis of that in http://thread.gmane.org/gmane.linux.kernel/772928/focus=773452
AFAIK the reasons stated there are all still valid.
