Subject: [PATCH v3 0/3] 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. More details can be found
in the respective changelogs. Thanks!
