HWPOISON: add an interface to switch off/on all the page filters
In some use cases, user doesn't need extra filtering. E.g. user program
can inject errors through madvise syscall to its own pages, however it
might not know what the page state exactly is or which inode the page
belongs to.
So introduce an one-off interface "corrupt-filter-enable".
Echo 0 to switch off page filters, and echo 1 to switch on the filters.
[AK: changed default to 0]
