This is my third time submitting this version of the patch in the last two months. Both prior submissions have not received any comments from (nor have they been applied by) the x86 maintainers. I don't really know what else to do at this point beyond "complain to the management" as it were. I appreciate anything you can do to unjam things here. - Kyle
