| * 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. |

| * |
| * 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 |
