Patch series "mm: hwpoison: fixlet for hugetlb migration". This patchset updates the hwpoison/hugetlb code to address 2 reported issues. One is madvise(MADV_HWPOISON) failure reported by Intel's lkp robot (see http://lkml.kernel.org/r/20170417055948.GM31394@yexl-desktop.) First half was already fixed in mainline, and another half about hugetlb cases are solved in this series. Another issue is "narrow-down error affected region into a single 4kB page instead of a whole hugetlb page" issue, which was tried by Anshuman (http://lkml.kernel.org/r/20170420110627.12307-1-khandual@linux.vnet.ibm.com) and I updated it to apply it more widely. This patch (of 9): We no longer use MIGRATE_ISOLATE to prevent reuse of hwpoison hugepages as we did before. So current dequeue_huge_page_node() doesn't work as intended because it still uses is_migrate_isolate_page() for this check. This patch fixes it with PageHWPoison flag.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
