mapping back to 36 bit physical

[Claudia Salzberg]

Greetings.
How does one go about aquiring the 36-bit physical address on a 440XX if
you have the corresponding va from an ioremap (when your driver is not
the one that did the ioremap so that you don't have the pa saved)?  I see
that ioremap does support 36-bit I/O mapping but _va and _pa only play
with unsigned long's.  So does iopa.  So do the virt_to_* 's I was able
to find.  Also, does anyone have plans for incorporating memory access
hooks above 4GB address space?

Thanks,

Claudia Salzberg
