This patch goes a long way toward fixing the minifail bug, and it
significantly
improves the stability of SMP machines such as the rp3440. When
write protecting
a page for COW, we need to purge the existing translation.
Otherwise, the COW
break doesn't occur as expected.
The patch assumes the kernel will flush page when it does copy.
