    This patch appears to be empty. Also, quilt barfs on such things.
    The patch as it appeared in broken-out/ is attached.

    Here is a patchset to fix a bug of m32r kernel 2.6.9 that a code on
    a noexec page can be executed incorrectly.

    For good security, stack region should be non-executable.
    This fix is also needed to achieve non-executable stack.

    Please apply this to 2.6.10 kernel if possible.

    Thank you.

    - Cause a segmentation fault for an illegal execution of a code on
    non-executable memory page.

    [PATCH 2.6.10-rc3-mm1] m32r: Don't encode ACE_INSTRUCTION in address (2/3)

    instead of encoding it into address parameter.
