Subject: EDAC, MCE: Add support for F11h MCEs
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f0157b3afd2ec6331245768a785487249a3c9734;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

EDAC, MCE: Add support for F11h MCEs

F11h has almost the same MCE signatures as K8 except DRAM ECC and MC5
bank errors. Reuse functionality from the other families.
