This patch was written by Martin Bligh.

Please consider this patch for inclusion into the 2.4.20pre tree. It
has been accepted to the aa tree. This version of the patch is just
a forward port of the aa patch.

This patch changes all references of node_start_paddr and zone_start_paddr
to node_start_pfn and zone_start_pfn. This change is required to support PAE
for i386 discontigmem.

Here's Martin's previous discussion regarding these changes:

I've tested this patch on the following configurations: UP, SMP, SMP PAE,
multiquad, multiquad PAE, multiquad DISCONTIGMEM, multiquad DISCONTIGMEM PAE.

Any and all feedback regarding this patch is greatly appreciated.

Thanks,
Pat
