- * (c) 1995 Alan Cox, Building #3 <[EMAIL PROTECTED]>
- * (c) 1998, 1999, 2000 Ingo Molnar <[EMAIL PROTECTED]>
- * Copyright 2001 Andi Kleen, SuSE Labs.
- *
- * Much of the core SMP work is based on previous work by Thomas Radke, to
- * whom a great many thanks are extended.
- *
- * Thanks to Intel for making available several different Pentium,
- * Pentium Pro and Pentium-II/Xeon MP machines.
- * Original development of Linux SMP code supported by Caldera.
- *
- * This code is released under the GNU General Public License version 2
- *
- * Fixes
- * Felix Koop : NR_CPUS used properly
- * Jose Renau : Handle single CPU case.
- * Alan Cox : By repeated request 8) - Total BogoMIP
report.
- * Greg Wright : Fix for kernel stacks panic.
- * Erich Boleyn : MP v1.4 and additional changes.
- * Matthias Sattler : Changes for 2.1 kernel map.
- * Michel Lespinasse : Changes for 2.1 kernel map.
- * Michael Chastain : Change trampoline.S to gnu as.
- * Alan Cox : Dumb bug: 'B' step PPro's are fine
- * Ingo Molnar : Added APIC timers, based on code
- * from Jose Renau
- * Ingo Molnar : various cleanups and rewrites
- * Tigran Aivazian : fixed "0.00 in /proc/uptime on SMP" bug.
- * Maciej W. Rozycki : Bits for genuine 82489DX APICs
- * Andi Kleen : Changed for SMP boot into long mode.
- * Rusty Russell : Hacked into shape for new "hotplug"
boot process.
- * Andi Kleen : Converted to new state machine.
- * Various cleanups.
- * Probably mostly hotplug CPU ready now.
- * Ashok Raj : CPU hotplug support
