From 693bf0aa01b7f9a1b24b2b932d555c6667f17a1a Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Thu, 20 Jul 2017 11:23:07 +0200 Subject: [PATCH] x86/boot: Fix memremap() related build failure MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The following commit: 5997efb96756 ("x86/boot: Use memremap() to map the MPF and MPC data") causes new build failures on certain randconfigs: drivers/sfi/sfi_core.c: In function ‘sfi_map_memory’: drivers/sfi/sfi_core.c:104:10: error: implicit declaration of function ‘memremap’ [-Werror=implicit-function-declaration] drivers/sfi/sfi_core.c:104:31: error: ‘MEMREMAP_WB’ undeclared (first use in this function) This is a case of parasitic header dependencies: the sfi_core.c file indirectly includes for typical - but not all configs. Including explicitly solves the build failure.
