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

From: Hirokazu Takata <>


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.

instead of encoding it into address parameter.
