[PATCH 0/12] Enable non-zero KERNELBASE

For kdump we need to boot the kernel at somewhere other than zero, because
the first kernel is already running (or crashed) at zero.

This series of patches makes changes to allow us to boot a kernel at 32 MB.

The first six patches, up to "Add a is_kernel_addr() macro", are preparatory
changes and are good to merge if no one objects. (on top of the current
for-2.6.14 branch)

The remaining six patches are still experimental. Feedback requested!

There's still a few KERNELBASE references lying around that I haven't checked
out yet, I'll get to them soonish.

Booted at zero and 32MB on P5 LPAR, Power3 and G5.
