This also extends the code to handle 32-bit ELF vmlinux files as well
as 64-bit ones. This is sufficient for booting on new-world 32-bit
powermacs (i.e. all recent machines).

'make install' creates a /boot/zImage[.vmode] file when the defconfig is used.
It uses the second arg as file content, which is the vmlinux, and the 5th
arg as file name, which is the BOOTIMAGE name.
A comment in an earlier patch to install.sh states that yaboot can not load
a zImage+initrd combo. This was true in kernel 2.6.5 because it did use
bi_recs to pass the initrd info. But this concept was always broken.
Register r3 holds the initrd address and r4 holds the initrd size. This
works with all kernel versions. The current code in main.c leaves r3 and
r4 alone, so the kernel should be able to see and use the memory range with
the initrd content.
If one wants to rerun mkinitrd, it is currently hard to get the uname -r
value for the installed zImage. Without this info, mkinitrd can not know
what modules to use. This would be fixable by including the /proc/version
output of the new kernel. But it is simpler to just use the plain vmlinux.
So all this patch does is to write to /boot/vmlinux instead to /boot/zImage

The attached patch causes the various arch specific install.sh scripts to
look for ${CROSS_COMPILE}installkernel rather than just installkernel (in
both /sbin/ and ~/bin/ where the script already did this). This allows you
to have e.g. arm-linux-installkernel as a handy way to install on your
cross target. It also prevents the script picking up on the host
/sbin/installkernel which causes the script to fall through and do the
install itself (which is what I actually use myself, with $INSTALL_PATH
set).
I don't believe it causes back-compatibility problems since calling the
host installkernel was never likely to work or be what you wanted when
cross compiling anyway. If $CROSS_COMPILE isn't set then nothing changes.
I only use ARM and i386 myself but I figured it couldn't hurt to do the
whole lot. I've cc'd those who I hope are the arch maintainers for files
that I've touched.

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!
