From: Mike Rapoport Date: Sun, 12 Feb 2023 08:46:11 +0000 (+0200) Subject: char/agp: introduce asm-generic/agp.h X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=a13408c205260716e925a734ef399899d69182ba;p=linux.git char/agp: introduce asm-generic/agp.h There are several architectures that duplicate definitions of map_page_into_agp(), unmap_page_from_agp() and flush_agp_cache(). Define those in asm-generic/agp.h and use it instead of duplicated per-architecture headers.
