Hi.
Attached are some changes to address the problem that modifications to
the contents of a file, made via an mmap'd region, do not cause the
modification time on the file to be updated. This lack can cause corruption
by allowing backup software to not detect files which should be backed up.

Fix the fact that pte_mkread set _PAGE_RW instead of _PAGE_USER (the logic is
copied from i386 in most place, so it is really as bad as you're thinking).
Thus currently page tables are more permissive than they should.
Such a change may trigger other latent bugs, so be careful with this.
