Hi,
I wrote "HWPOISON for hugepage" patchset last year, but it didn't
cover the hugepages used by KVM guest because follow_hugetlb_pages()
called in a guest page fault code path didn't know about swap entry
formatted pmd entry.
This patchset fixes it and makes both soft and hard offline available
on hugepage backed KVM guest.
I appreciate all of your comments and reviews.
Thanks,
Naoya Horiguchi
