From 03bc8b0fc87616c75c6dd060a2191e7fc8faacb6 Mon Sep 17 00:00:00 2001 From: Christophe Leroy Date: Tue, 22 Sep 2015 16:34:23 +0200 Subject: [PATCH] powerpc32: checksum_wrappers_64 becomes checksum_wrappers The powerpc64 checksum wrapper functions adds csum_and_copy_to_user() which otherwise is implemented in include/net/checksum.h by using csum_partial() then copy_to_user() Those two wrapper fonctions are also applicable to powerpc32 as it is based on the use of csum_partial_copy_generic() which also exists on powerpc32 This patch renames arch/powerpc/lib/checksum_wrappers_64.c to arch/powerpc/lib/checksum_wrappers.c and makes it non-conditional to CONFIG_WORD_SIZE Signed-off-by: Christophe Leroy Signed-off-by: Scott Wood --- arch/powerpc/include/asm/checksum.h | 9 --------- arch/powerpc/lib/Makefile | 3 +-- .../lib/{checksum_wrappers_64.c => checksum_wrappers.c} | 0 3 files changed, 1 insertion(+), 11 deletions(-) rename arch/powerpc/lib/{checksum_wrappers_64.c => checksum_wrappers.c} (100%) diff --git a/arch/powerpc/include/asm/checksum.h b/arch/powerpc/include/asm/checksum.h index d2ca07bb8837..afa6722cb7d2 100644 --- a/arch/powerpc/include/asm/checksum.h +++ b/arch/powerpc/include/asm/checksum.h @@ -47,21 +47,12 @@ extern __wsum csum_partial_copy_generic(const void *src, void *dst, int len, __wsum sum, int *src_err, int *dst_err); -#ifdef __powerpc64__ #define _HAVE_ARCH_COPY_AND_CSUM_FROM_USER extern __wsum csum_and_copy_from_user(const void __user *src, void *dst, int len, __wsum sum, int *err_ptr); #define HAVE_CSUM_COPY_USER extern __wsum csum_and_copy_to_user(const void *src, void __user *dst, int len, __wsum sum, int *err_ptr); -#else -/* - * the same as csum_partial, but copies from src to dst while it - * checksums. - */ -#define csum_partial_copy_from_user(src, dst, len, sum, errp) \ - csum_partial_copy_generic((__force const void *)(src), (dst), (len), (sum), (errp), NULL) -#endif #define csum_partial_copy_nocheck(src, dst, len, sum) \ csum_partial_copy_generic((src), (dst), (len), (sum), NULL, NULL) diff --git a/arch/powerpc/lib/Makefile b/arch/powerpc/lib/Makefile index a47e14277fd8..e46b06822bea 100644 --- a/arch/powerpc/lib/Makefile +++ b/arch/powerpc/lib/Makefile @@ -22,8 +22,7 @@ obj64-$(CONFIG_SMP) += locks.o obj64-$(CONFIG_ALTIVEC) += vmx-helper.o ifeq ($(CONFIG_GENERIC_CSUM),) -obj-y += checksum_$(CONFIG_WORD_SIZE).o -obj-$(CONFIG_PPC64) += checksum_wrappers_64.o +obj-y += checksum_$(CONFIG_WORD_SIZE).o checksum_wrappers.o endif obj-$(CONFIG_PPC_EMULATE_SSTEP) += sstep.o ldstfp.o diff --git a/arch/powerpc/lib/checksum_wrappers_64.c b/arch/powerpc/lib/checksum_wrappers.c similarity index 100% rename from arch/powerpc/lib/checksum_wrappers_64.c rename to arch/powerpc/lib/checksum_wrappers.c -- GitLab
