Hi, I wasn't involved in any BadRAM discussions so I can only do these statements from reading mailing list discussions[1].

and came across a patch for the kernel which purports to use a feature of the kernel to map bad RAM bytes and not use them thus avoiding the need to replace RAM (perhaps unnecessarily). The patches do not go beyond kernel 2.6.x. The patch hasn't been accepted yet (if it gets accepted at all is questionable). There are some concerns about the interface for bad addresses specification.
I was wondering if this patch is now automatically built-in into the kernel and patching the kernel is therefore no longer necessary (I am using kernel 3.2 for example)? No, it is not a part of the upstream (vanilla) nor our opensuse kernels. The patch would need to be accepted (or at least there was a consensus that it _will_ be in a compatible form) into upstream before we will take it.
Thanks for your response. The patch has been around for some time I believe but then things move slowly when one is having fun :-) .
