[PATCH] (1/2) i386 discontigmem support against 2.4.21pre1: paddr_to_pfn

This patch was originally written by Martin Bligh.

It 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.  It allows a starting address 
for a node or zone to be greater than 4GB. A version of this patch 
is in the 2.4 aa tree and has also been accepted into the v2.5 tree 
starting with 2.5.34.

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

The patch looks cool.  If it was inline in the mail instead of beeing a
mime-attachment everyone could even see that easily 8)
