[Kernel-packages] [Bug 1520411] Re: powerpc/tm: Fix local DoS

[Luis Henriques]

This bug is awaiting verification that the kernel in -proposed solves
the problem. Please test the kernel and update this bug with the
results. If the problem is solved, change the tag 'verification-needed-
wily' to 'verification-done-wily'.

If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

I built a Wily test kernel with a cherry pick of the two requested
commits.  The test kernel can be downloaded from:

http://kernel.ubuntu.com/~jsalisbury/lp1520411/

Can you test this kernel an see if it resolves this bug?
