That series was superseded by: lore.kernel.org/r/1562086280-5351-1-git-send-email-baicar@os.amperecomputing.com Can you work with Tyler on a combined series? The combined support may need to look quite different. (DT and big/little being the obvious differences). I'm afraid this is the tip of the kernel-first-RAS iceberg. Thanks, James
