This has some bigger consequences, but again it's much more easy to
work with relocatables in a NUMA environment.
In particular, the effects of this change are:
1. We can't load kernels any more -- not a big deal for Altix, because
we couldn't load kernels in the first place. We needed to load the
kernel at a fixed physical address (= 64M) and on Altix there's no
physical memory at that address.
2. The kernel object size increased by ~39%. The debug kernel object
file increased by about ~99%. Lastly, the symbols object file saw
about a 150% increase. Whether this is acceptable or not is left
for later to decide -- after we can compare the memory footprint.
3. The loader can't check for ET_EXEC to determine if the object is
the kernel proper or not. Consequently, we have no entry point. It
feels acceptable to expect the entry point to be called "__start"
or something along those lines. The kernel proper is the object
file that contains that symbol.
