Deal with odd kernel behavior
Some versions of gnumach actually take address as a mapping hint, and would fail
if the hint is bogus. Make sure to pass 0 for those versions.
* console/pager.c (user_pager_create): Make sure to set *user to 0 before
calling vm_map.
* libdiskfs/disk-pager.c (diskfs_start_disk_pager): Make sure to set *image to 0
before calling vm_map.
* libpager/pager-memcpy.c (pager_memcpy): Set window to 0 before calling
vm_map.
* tmpfs/node.c (diskfs_get_filemap): Make sure to set np->dn->u.reg.memref to 0
before calling vm_map.
