ARM26 define FIRST_USER_ADDRESS as PAGE_SIZE (beyond the machine vectors
when they are mapped low), and use that definition in place of locally
defined MIN_MAP_ADDR. Previously, ARM26 permitted user mappings at 0 if
the machine vectors were mapped high; but that's inconsistent with ARM,
and FIRST_USER_ADDRESS would then have to be determined at runtime.
Let's fix it at PAGE_SIZE throughout the architecture.
This is correct because ARM26 cant map vectors high at all.
