[PATCH] doc: alphabetize kernel-parameters.txt
From: Randy Dunlap
Date: Thu Feb 12 2009 - 17:58:27 EST
From: Randy Dunlap <randy.dunlap@xxxxxxxxxx>
kernel-parameters.txt specifies that entries are supposed to be in
alpha order, so rearrange lots of entries to support that.
Also clean up some vertical whitespace.
