2006-09-26[PATCH] i386: Replace i386 open-coded cmdline parsing withRusty Russell
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 <rusty@rustcorp.com.au> Signed-off-by: Andi Kleen <ak@suse.de>
2006-09-26[PATCH] i386: Allow to use GENERICARCH for UP kernelsAndi Kleen
There are some machines around (large xSeries or Unisys ES7000) that need physical IO-APIC destination mode to access all of their IO devices. This currently doesn't work in UP kernels as used in distribution installers. This patch allows to compile even UP kernels as GENERICARCH which allows to use physical or clustered APIC mode.

2006-05-30[PATCH] i386: apic= command line option should always beJan Beulich
From: "Jan Beulich" <jbeulich@novell.com> When using apic= on the kernel command line, this had no effect for machines matched by either the ACPI MADT or the MPS OEM table scan. However, when such option is specified, it should also take effect for this set of systems.

2005-09-05[PATCH] x86: sutomatically enable bigsmp when we have more than 8 CPUsVenkatesh Pallipadi
i386 generic subarchitecture requires explicit dmi strings or command line to enable bigsmp mode. The patch below removes that restriction, and uses bigsmp as soon as it finds more than 8 logical CPUs, Intel processors and xAPIC support.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
