bitkeeper revision 1.1159.42.2 (4124b039yQGTqk4tjyHEoXGty5VlPg)

Fix use of the phys_to_machine_mapping table in Linux 2.4 and 2.6.
We now ensure that the table contains no MFNs that do not belong
the OS --- invalid entries contain a sentinel value; deliberate
foreign mappings have the high bit set. This means the pte_page() and
pte_pfn() will do the right thing despite possible aliasing in the
M2P table.
