Since introducing the ability to have large folios in the page cache, it's been possible to have a hwpoisoned tail page returned from the fault handler. We handle this situation poorly; failing to remove the affected page from use. This isn't a minimal patch to fix it, it's a full conversion of all the code surrounding it. I'll take care of backports to 6.5/6.1.
