machine_specific_memory_setup() makes the following call to setup e820:

    add_memory_region(0, PFN_PHYS(max_pfn), E820_RAM);

Since max_pfn is (rightly) an unsigned long, we overflow for the current
definition of PFN_PHYS. Attached is my preferred solution as it will
hopefully avoid similar situations that may come up in the future.
