kernel-maverick-upstart: pass entire command line to init
 

As part of the blueprint kernel-maverick-upstart[1] we have been
investigating passing all of the kernel command line to init. This allows
upstart to know everything that was passed so that we can share options,
for example quiet.

Below are sample options list as dumped by an additional debugging patch.
In each case the orginal boot line is the same. With the option disabled,
ie. normal boot semantics:

[ 0.000000] environ<BOOT_IMAGE=/boot/vmlinuz-2.6.34-4-generic>
[ 0.000000] argument<splash>

With the option enabled:

[ 0.000000] environ<BOOT_IMAGE=/boot/vmlinuz-2.6.34-4-generic>
[ 0.000000] environ<root=UUID=bb5209a0-aca5-49da-b99b-52eff65f986b>
[ 0.000000] argument<ro>
[ 0.000000] argument<quiet>
[ 0.000000] argument<splash>

Note that the semantics of init=foo <arg> <arg> ... are unchanged.

The following patch set implements this for Maverick. Proposing for
Maverick.
