Subject: [PATCH v4 0/5] A few fixup patches for mm

Hi everyone,
This series contains a few patches to avoid mapping random data if swap
read fails and fix lost swap bits in unuse_pte. Also we free hwpoison and
swapin error entry in madvise_free_pte_range and so on. More details can
be found in the respective changelogs. Thanks!
