Subject[PATCH 21/25] kbuild: Fix 100% initramfs bloat in 2.6.17 versus 2.6.16
-stable review patch.  If anyone has any objections, please let us know.
------------------

From: Nix <nix@esperi.org.uk>

When I built 2.6.17 for the first time I was a little surprised to see
my kernel putting on >500Kb in weight.

It didn't take long to work out that this was because my initramfs's
contents were being included twice in the cpio image.

A make V=1 makes the problem obvious:

/bin/sh /usr/packages/linux/versions/i686-loki/scripts/gen_initramfs_list.sh -l "usr/initramfs" > usr/.initramfs_data.cpio.gz.d
/bin/sh /usr/packages/linux/versions/i686-loki/scripts/gen_initramfs_list.sh -o usr/initramfs_data.cpio.gz -u 0 -g 0 "usr/initramfs" "usr/initramfs"

Note that doubling-up of the "usr/initramfs", which leads to
gen_initramfs_list.sh dumping the thing into the cpio archive twice.

The cause is an obvious pasto, fixed thusly:
