Subject: [PATCH] x86: corruption check: move the corruption checks into their own file
The corruption check code is rather sizable and it's likely to grow over
time when we add checks for more types of corruptions (there's a few
candidates in kerneloops.org that I want to add checks for)... so lets move
it to its own file

Subject: [PATCH] x86: corruption check: run the corruption checks from a work queue
the periodic corruption checks are better off run from a work queue; there's
nothing time critical about them and this way the amount of
interrupt-context work is reduced.

Hi,
Did you figure out what's causing these corruptions yet?
Can't you do so by simply reserving the memory area in question,
clearing the present bit for those pages, and letting the page fault
handler catch whatever code is accessing it?

now that the code is moved and converted to a work queue,
there's some minor cleanups that can be done.
