Its filename is mm-pgtable-add-shortcuts-for-accessing-kernel-pmd-and-pte-fix.patch This patch should soon appear at http://ozlabs.org/~akpm/mmots/broken-out/mm-pgtable-add-shortcuts-for-accessing-kernel-pmd-and-pte-fix.patch and later at http://ozlabs.org/~akpm/mmotm/broken-out/mm-pgtable-add-shortcuts-for-accessing-kernel-pmd-and-pte-fix.patch Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next and is updated there every 3-4 working days ------------------------------------------------------ From: Mike Rapoport Subject: microblaze: fix page table traversal in setup_rt_frame() The replacement of long folded page table traversal with the direct access to PMD entry wrongly used the kernel page table in setup_rt_frame() function instead of the process (current->mm) page table. Fix it.
