Whilst I've queued the main NUMA series for arm64, I'd really like to see more movement on the generic header file cleanups that you posted separately: http://lkml.kernel.org/r/1456358528-24213-1-git-send-email-ddaney.cavm@xxxxxxxxx Given that this ACPI series already requires some significant cross-arch interaction (which is actually good!), perhaps extending the clean-up patches to encompass some of the ACPI bits might make sense, and we can get that queued as a pre-requisite.
