ffa27b6bc6 [PATCH] ppc64 memory model depends on NUMA
Currently when we first select memory model (FLAT, DISCONTIG, SPARSE) then
select whether the machine is NUMA.  However NUMA systems may not be FLAT.
This constraint it not honoured and we may configure a NUMA/FLAT system.

Reorder the configuration such that we choose NUMA first which allows us to
only list the memory models which are valid.  We now default NUMA for known
NUMA systems.  Note that this new order also matches that used in x86.

18c5332bc1 [PATCH] ppc64: change name of target file during make install
'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
