Linux-2.6.12-rc2 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!

[PATCH] i386: Allow to use GENERICARCH for UP kernels 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.

drivers/firmware: const-ify DMI API and internals Three main sets of changes: 1) dmi_get_system_info() return value should have been marked const, since callers should not be changing that data. 2) const-ify DMI internals, since DMI firmware tables should, whenever possible, be marked const to ensure we never ever write to that data area. 3) const-ify DMI API, to enable marking tables const where possible in low-level drivers. And if we're really lucky, this might enable some additional optimizations on the part of the compiler. The bulk of the changes are #2 and #3, which are interrelated. #1 could have been a separate patch, but it was so small compared to the others, it was easier to roll it into this changeset.

CPU apic id is [4,11] instead of [0,7], and we need to check max apic id instead of cpu numbers. also add check for 32 bit when acpi is not compiled in or acpi=off.
