This is a snapshot of my -mm patch queue.  Uploaded at random hopefully
more than once a week.

You will need quilt to apply these patches to the latest Linus release (5.x
or 5.x-rcY).  The series file is in broken-out.tar.gz and is duplicated in
https://ozlabs.org/~akpm/mmotm/series

The file broken-out.tar.gz contains two datestamp files: .DATE and
.DATE-yyyy-mm-dd-hh-mm-ss.  Both contain the string yyyy-mm-dd-hh-mm-ss,
followed by the base kernel version against which this patch series is to
be applied.

This tree is partially included in linux-next.  To see which patches are
included in linux-next, consult the `series' file.  Only the patches
within the #NEXT_PATCHES_START/#NEXT_PATCHES_END markers are included in
linux-next.

on x86_64:
# CONFIG_HUGETLBFS is not set

../mm/memory-failure.c: In function ‘__get_hwpoison_page’:
../mm/memory-failure.c:962:15: error: ‘hugetlb_lock’ undeclared (first use in this function); did you mean ‘huge_pte_lock’?
    spin_lock(&hugetlb_lock);

Thanks, we need "#ifdef CONFIG_HUGETLB_PAGE" for the added code.
And this patch is still under discussion and needs to be updated.
So Andrew, could you drop the following patches from linux-mm?

mmhwpoison-make-get_hwpoison_page-call-get_any_page.patch added to -mm tree
mmhwpoison-fix-race-with-compound-page-allocation.patch added to -mm tree
