Remove large parts of amd64_edac_dbg.c, as a result, which did only NB MCE injection anyway and the new injection code supports that functionality already. Add an injection module so that MCE decoding code in production kernels like those in RHEL and SLES can be tested.

This doesn't make much sense since this error has been lost anyway so no need for reporting it separately. Thus, report the overflow bit setting in the MCE dump instead. While at it, remove reporting of MiscV and ErrorEnable (en) which are superfluous. Now it looks like this: [ 1501.650024] MC4_STATUS: Corrected error, other errors lost: yes, CPU context corrupt: no, CECC Error [ 1501.666887] Northbridge Error, node 2 Signed-off-by: Borislav Petkov <borislav.petkov@amd.com> 2010-08-24T16:06:54+00:00 Borislav Petkov borislav.petkov@amd.com 2010-08-06T16:55:45+00:00 urn:sha1:e045c29126eae3a8cfdf8507baa75b5c70fd4f53 Limit MCE error decoding to current and older families only (K8-F11h).
