A subset of these platforms are looking for extra versioning information appended to it, accessible via /proc/version. Rather than build multiple otherwise identical kernels with only this extended versioning as differentiation, we are looking to make this a command line parameter. Understandable if there isn't enough value-add for the community in this patch, but I figured I'd give the patch a shot, as we need this functionality locally. Thanks.

Please use a newline character every 70-72 characters instead of assuming
that all email programs will break that extra long line up into a readable
format. (mine does not.)

What software needs to know the version info? how early does it run?
Could it get the version info from 'uname -r' instead of from /proc/version?

thanks,
