remove Documentation/smp.txt 



After seeing the filename I'd have expected something about the
implementation of SMP in the Linux kernel - not some notes on kernel
configuration and building trivialities noone would search at this
place.

To set up SMP



Configure the kernel and answer Y to CONFIG_SMP.



If you are using LILO, it is handy to have both SMP and non-SMP

kernel images on hand. Edit /etc/lilo.conf to create an entry

for another kernel image called "linux-smp" or something.



The next time you compile the kernel, when running a SMP kernel,

edit linux/Makefile and change "MAKE=make" to "MAKE=make -jN"

(where N = number of CPU + 1, or if you have tons of memory/swap

 you can just use "-j" without a number). Feel free to experiment

with this one.



Of course you should time how long each build takes :-)

Example:

   make config

   time -v sh -c 'make clean install modules modules_install'



If you are using some Compaq MP compliant machines you will need to set

the operating system in the BIOS settings to "Unixware" - don't ask me

why Compaqs don't work otherwise.
