[PATCH] uml: pte_mkread fix
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.
