The new Gumstix uses the Cortex OMAP processor as well.

I sent Oliver a link to the start of the ARMv6 UP/SMP cpu_throw/cpu_switch
and atomic code that is backward compatible and tested on pre-ARMv6;
obviously not yet on ARMv6.

In ARMv6 mode, the caches are not flushed on context change. ARMv6 UP
and SMP have different caches: SMP does not use the pmap_fix_cache and
the multiple KVA patch, and the ARMv6 UP and ARMv5 use a different
definition of page sharing (ARMv6 uses page coloring), therefore the flushing
circumstances change.

In the patch that I sent to him, there are still some flushes to be removed
from pmap.c. We will see; maybe ARMv5, ARMv6 UP and SMP should use a
different pmap.c file.
