I thought you needed to solve the problem of loadable kernel modules?
I think that means that any kernel structures that might be referenced
by a loadable module must contain space for a 64bit paddr_t.
This would include kernels that are build without PAE support.
Internally a non-PAE kernel will probably want to use 32bit arithmetic
for any calculations.
This might mean using a structure for paddr_t !
