Anton Ivanov 8892d8545f um: Avoid marking pages with "changed protection" 
Changing protection is a very high cost operation in UML
because in addition to an extra syscall it also interrupts
mmap merge sequences generated by the tlb.

While the condition is not particularly common it is worth
avoiding.
