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! 2005-04-16 15:20:36 -07:00			`#ifndef __ASM_MACH_APICDEF_H`

i386: fix 4 bit apicid assumption of mach-default Fix get_apic_id() in mach-default, so that it uses 8 bits incase of xAPIC case and 4 bits for legacy APIC case. This fixes the i386 kernel assumption that apic id is less than 16 for xAPIC platforms with 8 cpus or less and makes the kernel boot on such platforms.
