From: Tom Rini - Remove saved_command_line (and saving of the command line). - Call parse_early_options - Convert debug=, switches= to __early_param. And from Geert Uytterhoeven - Rename CL_SIZE to COMMAND_LINE_SIZE to fix compilation of init/main.c and match majority of other arches (MIPS needs a similar fix). - Move Atari-specific part from arch/m68k/kernel/setup.c to arch/m68k/atari/config.c, so we can drop the #ifdef CONFIG_ATARI --- 25-akpm/arch/m68k/atari/config.c | 13 ++++++- 25-akpm/arch/m68k/kernel/setup.c | 54 ++++++++++-------------------- 25-akpm/arch/m68k/kernel/vmlinux-std.lds | 3 + 25-akpm/arch/m68k/kernel/vmlinux-sun3.lds | 3 + 25-akpm/arch/m68k/mac/config.c | 2 - 25-akpm/arch/m68k/q40/config.c | 1 25-akpm/include/asm-m68k/bootinfo.h | 4 +- 25-akpm/include/asm-m68k/setup.h | 4 +- 8 files changed, 41 insertions(+), 43 deletions(-) diff -puN arch/m68k/atari/config.c~early-param-m68k arch/m68k/atari/config.c --- 25/arch/m68k/atari/config.c~early-param-m68k 2004-04-01 02:06:08.673060896 -0800 +++ 25-akpm/arch/m68k/atari/config.c 2004-04-01 02:06:08.687058768 -0800 @@ -180,7 +180,7 @@ int __init atari_parse_bootinfo(const st /* Parse the Atari-specific switches= option. */ -void __init atari_switches_setup( const char *str, unsigned len ) +static void __init atari_switches_setup( const char *str, unsigned len ) { char switches[len+1]; char *p; @@ -217,6 +217,17 @@ void __init atari_switches_setup( const } } +static int __init early_switches(char *p) +{ + char *q; + + atari_switches_setup(p, (q = strchr(p, ' ' )) ?
