From: Michal Schmidt Date: Tue, 8 May 2007 07:24:49 +0000 (-0700) Subject: Fix compilation of drivers with -O0 X-Git-Tag: MMI-PSA29.97-13-9~43920 X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ee7b9e3706b9c5f90113eb16a1a84a1c01e09f95;p=GitHub%2FMotorolaMobilityLLC%2Fkernel-slsi.git Fix compilation of drivers with -O0 It is sometimes useful to compile individual drivers with optimization disabled for easier debugging. Currently drivers which use htonl() and similar functions don't compile with -O0. This patch fixes it. It also removes obsolete and misleading comments. This header is not for userspace, so we don't have to care about strange programs these comments mention. (akpm: -O0 probably isn't a good idea, but this code looks pretty crufty and unuseful) Signed-off-by: Michal Schmidt Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- diff --git a/include/linux/byteorder/generic.h b/include/linux/byteorder/generic.h index e86e4a938373..3dc715b02500 100644 --- a/include/linux/byteorder/generic.h +++ b/include/linux/byteorder/generic.h @@ -124,19 +124,8 @@ #define be32_to_cpus __be32_to_cpus #define cpu_to_be16s __cpu_to_be16s #define be16_to_cpus __be16_to_cpus -#endif - -#if defined(__KERNEL__) /* - * Handle ntohl and suches.
