From 299878bac326c890699c696ebba26f56fe93fc75 Mon Sep 17 00:00:00 2001 From: Laura Abbott Date: Mon, 8 May 2017 15:57:59 -0700 Subject: treewide: move set_memory_* functions away from cacheflush.h Patch series "set_memory_* functions header refactor", v3. The set_memory_* APIs came out of a desire to have a better way to change memory attributes. Many of these attributes were linked to cache functionality so the prototypes were put in cacheflush.h. These days, the APIs have grown and have a much wider use than just cache APIs. To support this growth, split off set_memory_* and friends into a separate header file to avoid growing cacheflush.h for APIs that have nothing to do with caches.
