Richard Henderson 6e29509abc linux-user/x86_64: Handle the vsyscall page in open_self_maps_{2,4} 
This is the only case in which we expect to have no host memory backing
for a guest memory page, because in general linux user processes cannot
map any pages in the top half of the 64-bit address space.
