commit: e726f3c368e7c1919a7166ec09c5705759f1a69d From: Borislav Petkov <[email protected]> Date: Mon, 6 Dec 2010 16:20:25 +0100 Subject: [PATCH] amd64_edac: Fix interleaving check
When matching error address to the range contained by one memory node, we're in valid range when node interleaving 1. is disabled, or 2. enabled and when the address bits we interleave on match the interleave selector on this node (see the "Node Interleaving" section in the BKDG for an enlightening example). Thus, when we early-exit, we need to reverse the compound logic statement properly.
