* (c) 1995 Alan Cox, Building #3 <alan@redhat.com>
|
|
* (c) 1998, 1999, 2000 Ingo Molnar <mingo@redhat.com>
|
|
*
|
|
* 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 or
|
|
* later.
|
|
*
|
|
* Fixes
|
|
* Felix Koop : NR_CPUS used properly
|
|
* Jose Renau : Handle single CPU case.
|
|
* Alan Cox : By repeated request 8) - Total BogoMIPS 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
|
|
* Martin J. Bligh : Added support for multi-quad systems
|
|
* Dave Jones : Report invalid combinations of Athlon CPUs.
|
|
* Rusty Russell : Hacked into shape for new "hotplug" boot process. */
