Currently, we only have the uapi variant for linux/const.h, so I am creating include/linux/const.h. I also added _UL(), _ULL() and ULL() because _AC() is mostly used in the form either _AC(..., UL) or _AC(..., ULL). I expect they will be replaced in follow-up cleanups. The underscore-prefixed ones should be used for exported headers.
