Subject: [PATCH] Dynamic kernel command-line - fixups
Remove in-source externs, linux/init.h is included in all cases.
This is a fixups for "Dynamic kernel command-line" patch.
It includes the ia64 fixup already added.
It also includes some uml __init fixups so that we can __initdata also its command_line.
[[[ I will resubmit it to next mm version as you requested,
I don't mean to bother you. if you find this simple
enough you have an option to include this. ]]]
