yes, it only occurs in SMP builds.
i havent seen the build error you mention below, but i think that's
because in a past discussion we determined that NOMMU ports should be
setting VMALLOC_START to 0 and VMALLOC_END to -1. is that no longer
the case ?
there are bunch more places where things would fail if
VMALLOC_{START,END} werent defined ...
