In epiphany_vm_fault():
https://github.com/parallella/parallella-linux/blob/4ee628ea226a/drivers/misc/epiphany.c#L1224

We should speculatively pre-fault a couple of pages after the faulting page to reduce the number of times the fault handler needs to be called to amortize the fault-handler overhead.
