The scsihosts boot parameter was removed in 2.5.73, but references to it
still exist in docs.  Cleanup below.

-SCSI Host Probing Issues
-
-Devfs allows you to identify SCSI discs based in part on SCSI host
-numbers. If you have only one SCSI host (card) in your computer, then
-clearly it will be given host number 0. Life is not always that easy
-is you have multiple SCSI hosts. Unfortunately, it can sometimes be
-difficult to guess what the probing order of SCSI hosts is. You need
-to know the probe order before you can use device names. To make this
-easy, there is a kernel boot parameter called "scsihosts". This allows
-you to specify the probe order for different types of SCSI hosts. The
-syntax of this parameter is:
-
-scsihosts=<name_1>:<name_2>:<name_3>:...:<name_n>
-
-where <name_1>,<name_2>,...,<name_n> are the names
-of drivers used in the /proc filesystem. For example:
-
-    scsihosts=aha1542:ppa:aha1542::ncr53c7xx
-
-
-means that devices connected to
-
-- first aha1542 controller   - will be /dev/scsi/host0/bus#/target#/lun#
-- first parallel port ZIP    - will be /dev/scsi/host1/bus#/target#/lun#
-- second aha1542 controller  - will be /dev/scsi/host2/bus#/target#/lun#
-- first NCR53C7xx controller - will be /dev/scsi/host4/bus#/target#/lun#
-- any extra controller       - will be /dev/scsi/host5/bus#/target#/lun#,
-                                       /dev/scsi/host6/bus#/target#/lun#, etc
-- if any of above controllers will not be found - the reserved names will
-  not be used by any other device.
-- /dev/scsi/host3/bus#/target#/lun# names will never be used
-
-
-You can use ',' instead of ':' as the separator character if you
-wish. I have used the devfsd naming scheme
-here.
-
-Note that this scheme does not address the SCSI host order if you have
-multiple cards of the same type (such as NCR53c8xx). In this case you
-need to use the driver-specific boot parameters to control this.
