The code used to walk IA-32e page-tables, and possibly PAE page-tables, uses the bit mask ~0xfff to get the next PML4E/PDPTE/PDE/PTE address. However, as we use a uint64_t to store the resulting address, that mask gets expanded to 0xfffffffffffff000 which not only ends up selecting reserved bits but also selects the XD bit (execute-disable) which happens to be enabled by Windows 8, causing qemu_get_ram_ptr() to abort. This commit fixes that problem by replacing ~0xfff by a correct mask that only selects the address bit range (ie. bits 51:12).
