control page: avoid "minor" page faults
By default, even private writable pages are mapped with the RW bit disabled in the PTE. This causes a "minor" page fault when the page is first written to. To avoid this, make sure that vm_inert_page() uses the proper page protection bits and mark the VMA as VM_IO to keep the rest of the VM code out.
