From 7d1362c0d05b8543807ab403ac8ce813cab41fa4 Mon Sep 17 00:00:00 2001 From: Adrian Bunk Date: Wed, 6 Dec 2006 20:40:38 -0800 Subject: [PATCH] cleanup asm/setup.h userspace visibility Make the contents of the userspace asm/setup.h header consistent on all architectures: - export setup.h to userspace on all architectures - export only COMMAND_LINE_SIZE to userspace - frv: move COMMAND_LINE_SIZE from param.h - i386: remove duplicate COMMAND_LINE_SIZE from param.h - arm: - export ATAGs to userspace - change u8/u16/u32 to __u8/__u16/__u32 Signed-off-by: Adrian Bunk Acked-by: Russell King Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- include/asm-arm/setup.h | 104 ++++++++++++++++++++++------------------- include/asm-arm26/setup.h | 4 ++ include/asm-avr32/setup.h | 4 ++ include/asm-frv/param.h | 1 - include/asm-frv/setup.h | 6 +++ include/asm-generic/Kbuild.asm | 1 + include/asm-i386/Kbuild | 1 - include/asm-i386/param.h | 1 - include/asm-i386/setup.h | 6 ++- include/asm-ia64/Kbuild | 1 - include/asm-m32r/setup.h | 9 +++- include/asm-m68k/setup.h | 6 ++- include/asm-m68knommu/setup.h | 5 ++ include/asm-mips/setup.h | 2 - include/asm-powerpc/setup.h | 3 -- include/asm-s390/setup.h | 3 +- include/asm-sh/setup.h | 6 ++- include/asm-sh64/setup.h | 6 +++ include/asm-x86_64/Kbuild | 1 - 19 files changed, 102 insertions(+), 68 deletions(-) diff --git a/include/asm-arm/setup.h b/include/asm-arm/setup.h index aa4b5782f0c9..e5407392afca 100644 --- a/include/asm-arm/setup.h +++ b/include/asm-arm/setup.h @@ -14,55 +14,57 @@ #ifndef __ASMARM_SETUP_H #define __ASMARM_SETUP_H +#include + #define COMMAND_LINE_SIZE 1024 /* The list ends with an ATAG_NONE node. */ #define ATAG_NONE 0x00000000 struct tag_header { - u32 size; - u32 tag; + __u32 size; + __u32 tag; }; /* The list must start with an ATAG_CORE node */ #define ATAG_CORE 0x54410001 struct tag_core { - u32 flags; /* bit 0 = read-only */ - u32 pagesize; - u32 rootdev; + __u32 flags; /* bit 0 = read-only */ + __u32 pagesize; + __u32 rootdev; }; /* it is allowed to have multiple ATAG_MEM nodes */ #define ATAG_MEM 0x54410002 struct tag_mem32 { - u32 size; - u32 start; /* physical start address */ + __u32 size; + __u32 start; /* physical start address */ }; /* VGA text type displays */ #define ATAG_VIDEOTEXT 0x54410003 struct tag_videotext { - u8 x; - u8 y; - u16 video_page; - u8 video_mode; - u8 video_cols; - u16 video_ega_bx; - u8 video_lines; - u8 video_isvga; - u16 video_points; + __u8 x; + __u8 y; + __u16 video_page; + __u8 video_mode; + __u8 video_cols; + __u16 video_ega_bx; + __u8 video_lines; + __u8 video_isvga; + __u16 video_points; }; /* describes how the ramdisk will be used in kernel */ #define ATAG_RAMDISK 0x54410004 struct tag_ramdisk { - u32 flags; /* bit 0 = load, bit 1 = prompt */ - u32 size; /* decompressed ramdisk size in _kilo_ bytes */ - u32 start; /* starting block of floppy-based RAM disk image */ + __u32 flags; /* bit 0 = load, bit 1 = prompt */ + __u32 size; /* decompressed ramdisk size in _kilo_ bytes */ + __u32 start; /* starting block of floppy-based RAM disk image */ }; /* describes where the compressed ramdisk image lives (virtual address) */ @@ -76,23 +78,23 @@ struct tag_ramdisk { #define ATAG_INITRD2 0x54420005 struct tag_initrd { - u32 start; /* physical start address */ - u32 size; /* size of compressed ramdisk image in bytes */ + __u32 start; /* physical start address */ + __u32 size; /* size of compressed ramdisk image in bytes */ }; /* board serial number.
