From mboxrd@z Thu Jan 1 00:00:00 1970 From: arnd@arndb.de (Arnd Bergmann) Date: Thu, 19 Nov 2015 13:41:53 +0100 Subject: [PATCH] mm: include linux/pfn.h for PHYS_PFN definition Message-ID: <5841074.QcbTqgbsZz@wuerfel> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org A change to asm-generic/memory_model.h caused a new build error in some configurations: mach-clps711x/common.c:39:10: error: implicit declaration of function 'PHYS_PFN' .pfn = __phys_to_pfn(CLPS711X_PHYS_BASE), This includes the linux/pfn.h header from the same file to avoid the error. Signed-off-by: Arnd Bergmann Fixes: bf1c6c9895de ("mm: add PHYS_PFN, use it in __phys_to_pfn()") --- I was listed as 'Cc' on the original patch, but don't see it in my inbox. I can queue up the fixed version in the asm-generic tree if you like that, otherwise please fold this fixup into the patch, or drop it if we want to avoid the extra #include. diff --git a/include/asm-generic/memory_model.h b/include/asm-generic/memory_model.h index c785a79d9385..5148150cc80b 100644 --- a/include/asm-generic/memory_model.h +++ b/include/asm-generic/memory_model.h @@ -1,6 +1,8 @@ #ifndef __ASM_MEMORY_MODEL_H #define __ASM_MEMORY_MODEL_H +#include + #ifndef __ASSEMBLY__ #if defined(CONFIG_FLATMEM)
