Documentation: move SCSI parameters to their own text file 



Move SCSI parameters from kernel-parameters.txt to their own text file.

This continues a trend of moving non-core parameters out of
kernel-parameters.txt.

See Documentation/kernel-parameters.txt for general information on

specifying module parameters.



This document may not be entirely up to date and comprehensive. The command

"modinfo -p ${modulename}" shows a current list of all parameters of a loadable

module. Loadable modules, after being loaded into the running kernel, also

reveal their parameters in /sys/module/${modulename}/parameters/. Some of these

parameters may be changed at runtime by the command

"echo -n ${value} > /sys/module/${modulename}/parameters/${parm}".
