CVE request: kernel: xfs heap overflow

[Xi Wang <xi.wang () gmail com>]

Commit ef14f0c1578dce4b688726eb2603e50b62d6665a introduced an integer
overflow in the ACL handling code, which could further lead to
heap-based buffer overflow via a crafted filesystem.

Upstream commits:
http://git.kernel.org/linus/fa8b18edd752a8b4e9d1ee2cd615b82c93cf8bba
http://git.kernel.org/linus/093019cf1b18dd31b2c3b77acce4e000e2cbc9ce

Both commits are needed to fix the vulnerability.

The vulnerability seems to first appear in 2.6.32-rc1.  3.2 contains
only the first commit.
