The patch "scripts/link-vmlinux.sh: only filter kernel symbols for arm"
has made it in now, which is good for all other architectures, but it
makes no difference  for nommu-arm, because CONFIG_PAGE_OFFSET is
still set.

The second patch from Jonathan Austin has not been applied yet, as of
today's linux-next, and it's exactly what I suggested. However it
won't work on ARM platforms that define their own PLAT_PHYS_OFFSET:
ebsa110, ep93xx, exynos, footbridge, integrator, iop13xx, ks8695,
omap1, realview, rpc, s5pv210 and sa1100. Fortunately these all have
MMUs, so in practice it won't hurt, but it doesn't seem correct.
