[PATCH] EDAC: core EDAC support code
This is a subset of the bluesmoke project core code, stripped of the NMI work which isn't ready to merge and some of the "interesting" proc functionality that needs reworking or just has no place in kernel. It requires no core kernel changes except the added scrub functions already posted. The goal is to merge further functionality only after the core code is accepted and proven in the base kernel, and only at the point the upstream extras are really ready to merge. From: doug thompson <norsk5@xmission.com> This converts EDAC to sysfs and is the final chunk neccessary before EDAC has a stable user space API and can be considered for submission into the base kernel.
