solution for memory pages having (excessive) corrected memory errors.
For different types of page, soft-offline has different behaviors / costs.

- For a raw error page, soft-offline migrates the in-use page's content to

- For a page that is part of a transparent hugepage, soft-offline splits the
transparent hugepage into raw pages, then migrates only the raw error page.
