b5a5e4c732 kbuild: fix unportability in gen_initramfs_list.sh
On a Mac OS X machine the output of ls -l is different from a standard
Linux machine. Use readlink instead of parsing a hardcoded field number
from the ls output.

4c6f2eb979 kbuild: add support for squashing uid/gid in gen_initramfs_list.sh
Sometimes it is useful to squash all uid's/gid's to 0:0 regardless of
current owner.  For example, in build systems that get run as arbitrary
users (uClinux-dist).  This adds a special "squash" keyword so you can do
'-g squash -u squash' and have ownership squashed to root.

eda890af79 kbuild: propagate errors from find in scripts/gen_initramfs_list.sh
If the find(1) in scripts/gen_initramfs_list.sh generates any errors, it
will cause gen_initramfs_list.sh to fail (because of "set -e"), however
the errors from find are not printed to the user. This is rather confusing:

~/src/powerpc$ make O=~/build/powerpc-cell32/
make[2]: *** [usr/initramfs_data.cpio.gz] Error 1
make[1]: *** [usr] Error 2
make[1]: *** Waiting for unfinished jobs....
make[1]: *** wait: No child processes.  Stop.
make: *** [_all] Error 2

It is much easier to work out what the problem is if we let the errors
from find hit the console, eg:

~/src/powerpc$ make O=~/build/powerpc-cell32/
find: /home/michael/initramfs-source/home: Permission denied
find: /home/michael/initramfs-source/lost+found: Permission denied
find: /home/michael/initramfs-source/opt: Permission denied
find: /home/michael/initramfs-source/root: Permission denied
make[2]: *** [usr/initramfs_data.cpio.gz] Error 1
make[1]: *** [usr] Error 2
make[1]: *** Waiting for unfinished jobs....
make[1]: *** wait: No child processes.  Stop.
make: *** [_all] Error 2

c299ec2d8e kbuild: handle compressed cpio initramfs-es
Make kbuild handle compressed cpio initramfs-es.  An already compressed
cpio is copied directly to usr/, while a non-compressed cpio is filtered
through gzip (no changes here) on its way to usr/.

If the user has created a compressed cpio by other means, this saves him
from uncompressing it, just to be compressed again by kbuild.

a26d79ca81 [PATCH] initramfs: handle more than one source dir or file list
Fix bug 7401.

Handle more than one source dir or file list to the initramfs gen scripts.

The Kconfig help for INITRAMFS_SOURCE claims that you can specify multiple
space-separated sources in order to allow unprivileged users to build an
image.  There are two bugs in the current implementation that prevent this
from working.

First, we pass "file1 dir2" to the gen_initramfs_list.sh script, which it
obviously can't open.

Second, gen_initramfs_list.sh -l outputs multiple definitions for
deps_initramfs -- one for each argument.

d39a206bc3 kbuild: rebuild initramfs if content of initramfs changes
initramfs.cpio.gz being build in usr/ and included in the
kernel was not rebuild when the included files changed.

To fix this the following was done:
- let gen_initramfs.sh generate a list of files and directories included
  in the initramfs
- gen_initramfs generate the gzipped cpio archive so we could simplify
  the kbuild file (Makefile)
- utilising the kbuild infrastructure so when uid/gid root mapping changes
  the initramfs will be rebuild

With this change we have a much more robust initramfs generation.

1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
