Currently page loaning (at least) is broken on ARM VIPT platforms.
The reason is that possible dirty cache lines are not taken into account
at the moment, following is a fix for this.

The fix is validated against the latest breakage related to the socket
page loaning reported earlier on the list.

This is close to what I checked in but actually has a few missing corner
cases.  The version I checked works for the always failing
scp sdp:/lib/libc.so .

Adding KASSERT's for PVF_DIRTY helped me track down the last bug in my code.
