I'm hacking some code in the kernel, and want to pass in a custom parameter
to the kernel (either at boot time, or after startup), which my new code will
use. This parameter is a number, ranging from 40 to 800, for example.
The existing boot command line parameters do not allow the use of a user
defined custom parameter to be passed in to the kernel. Is there a way to
do this, either during or after boot?
