Hi All,

I've rebased and reworked the PS3 highmem patches that Hector and Andre have
submitted.  They are now against Linux-3.3, and I plan for them to go upstream
for Linux-3.5.  I'll rebase them again once a few 3.4-rc's are out.

This work needs to be tested more, especially needed is testing of the passing of
data in the highmem region.  Please test and report.

Nathan, these patches fix the well known node names, so it would be best
if you could add support to test for pre-allocated highmem regions in
your FreeBSD port.

-Geoff
