Ralf,
I'm sending to you a very trivial patch.
It's related to memory start address that does not
start at 0. This can easily be handled with uses of
"pfn_to_phys" and "virt_to_phys" macros. But some
parts of the kernel don't use them, and do for
instance
"addr << PAGE_SHIFT".
The patch deals with such cases in pgtable-32.h. If
you agree with, I'll send others patches to remove
them from every places I found.
Francis
