Remove need for early lockdep init I think it was only needed for the printks and we can do them later. I put in a single early_printk so that we know the kernel is alive (early_printk doesn't need any locks) This makes some things easier for initialization of unwind for lockdep, which is needed by later patches. cc: mingo@elte.hu Signed-off-by: Andi Kleen --- arch/x86_64/kernel/head64.c | 8 +------- arch/x86_64/kernel/setup.c | 2 ++ 2 files changed, 3 insertions(+), 7 deletions(-) Index: linux/arch/x86_64/kernel/head64.c =================================================================== --- linux.orig/arch/x86_64/kernel/head64.c +++ linux/arch/x86_64/kernel/head64.c @@ -45,15 +45,12 @@ static void __init copy_bootdata(char *r new_data = *(int *) (x86_boot_params + NEW_CL_POINTER); if (!new_data) { if (OLD_CL_MAGIC != * (u16 *) OLD_CL_MAGIC_ADDR) { - printk("so old bootloader that it does not support commandline?!\n"); return; } new_data = OLD_CL_BASE_ADDR + * (u16 *) OLD_CL_OFFSET; - printk("old bootloader convention, maybe loadlin?\n"); } command_line = (char *) ((u64)(new_data)); memcpy(saved_command_line, command_line, COMMAND_LINE_SIZE); - printk("Bootdata ok (command line is %s)\n", saved_command_line); } void __init x86_64_start_kernel(char * real_mode_data) @@ -65,10 +62,7 @@ void __init x86_64_start_kernel(char * r asm volatile("lidt %0" :: "m" (idt_descr)); clear_bss(); - /* - * This must be called really, really early: - */ - lockdep_init(); + early_printk("Kernel alive\n"); /* * switch to init_level4_pgt from boot_level4_pgt Index: linux/arch/x86_64/kernel/setup.c =================================================================== --- linux.orig/arch/x86_64/kernel/setup.c +++ linux/arch/x86_64/kernel/setup.c @@ -355,6 +355,8 @@ void __init setup_arch(char **cmdline_p) { unsigned long kernel_end; + printk(KERN_INFO "Command line: %s\n", saved_command_line); + ROOT_DEV = old_decode_dev(ORIG_ROOT_DEV); screen_info = SCREEN_INFO; edid_info = EDID_INFO;
