From 1a3f239ddf9208f2e52d36fef1c1c4518cbbbabe Mon Sep 17 00:00:00 2001 From: Rusty Russell Date: Tue, 26 Sep 2006 10:52:32 +0200 Subject: [PATCH] i386: Replace i386 open-coded cmdline parsing with This patch replaces the open-coded early commandline parsing throughout the i386 boot code with the generic mechanism (already used by ppc, powerpc, ia64 and s390). The code was inconsistent with whether it deletes the option from the cmdline or not, meaning some of these will get passed through the environment into init. This transformation is mainly mechanical, but there are some notable parts: 1) Grammar: s/linux never set's it up/linux never sets it up/ 2) Remove hacked-in earlyprintk= option scanning. When someone actually implements CONFIG_EARLY_PRINTK, then they can use early_param(). [AK: actually it is implemented, but I'm adding the early_param it in the next x86-64 patch] 3) Move declaration of generic_apic_probe() from setup.c into asm/apic.h 4) Various parameters now moved into their appropriate files (thanks Andi). 5) All parse functions which examine arg need to check for NULL, except one where it has subtle humor value. AK: readded acpi_sci handling which was completely dropped AK: moved some more variables into acpi/boot.c Cc: len.brown@intel.com Signed-off-by: Rusty Russell Signed-off-by: Andi Kleen --- arch/i386/kernel/apic.c | 15 +++++++++++++++ 1 file changed, 15 insertions(+) (limited to 'arch/i386/kernel/apic.c') diff --git a/arch/i386/kernel/apic.c b/arch/i386/kernel/apic.c index 1a34fc5..ce75e71 100644 --- a/arch/i386/kernel/apic.c +++ b/arch/i386/kernel/apic.c @@ -1372,3 +1372,18 @@ int __init APIC_init_uniprocessor (void) return 0; } + +static int __init parse_lapic(char *arg) +{ + lapic_enable(); + return 0; +} +early_param("lapic", parse_lapic); + +static int __init parse_nolapic(char *arg) +{ + lapic_disable(); + return 0; +} +early_param("nolapic", parse_nolapic); + -- cgit v1.1
