From 2dd8a62c647691161a2346546834262597739872 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Tue, 10 Apr 2018 16:36:19 -0700 Subject: linux/const.h: move UL() macro to include/linux/const.h ARM, ARM64 and UniCore32 duplicate the definition of UL(): #define UL(x) _AC(x, UL) This is not actually arch-specific, so it will be useful to move it to a common header. 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.
