Subject[PATCH] 8: 2.5.29-rd
Date
This patch has been verified to apply cleanly to 2.5.30

This patch adds support for "initrd=start,size" on the kernel command
line. This allows us (the ARM folk) to give details of the initrd
on the (default) command line rather than hard-coding such stuff
into the kernel proper.
