Patch series "kasan: assorted clean-ups". Code clean-ups, nothing worthy of being backported to stable. This patch (of 11): Unify and improve the comments for KASAN_SHADOW_START/END definitions from include/asm/kasan.h and include/asm/memory.h. Also put both definitions together in include/asm/memory.h. Also clarify the related BUILD_BUG_ON checks in mm/kasan_init.c.
