[PATCH v1 0/2] mm: hwpoison: fix mce-test.ras.fail on 23a003bfd2

[Naoya Horiguchi <n-horiguchi@ah.jp.nec.com>]

Hello,

I wrote fixes for the problems reported by http://lkml.kernel.org/r/20170417055948.GM31394@yexl-desktop.
These 2 patches make tsimpleinj.c delivered in mce-test test suite pass.

  SUCCESS

I'm digging another similar issue for hugetlb pages, which need some more
research and code, so I'll send it separately later.

Thanks,
