[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 <bunk@stusta.de> Acked-by: Russell King <rmk@arm.linux.org.uk> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
