We have recently discovered an issue with Bulldozer instruction cache
which may cause certain loads to experience performance regressions.
http://marc.info/?l=linux-kernel&m=131134057927055&w=3 thread discusses
the problem and the fix.

We have patches queued for 3.2, they should also apply to 3.0:

1. http://git.kernel.org/tip/dfb09f9b7ab03fd367740e541a5caf830ed56726
2. http://git.kernel.org/tip/a110b5ec7371592eac856ac5c22dc7b518952d44
3. http://git.kernel.org/tip/8fa8b035085e7320c15875c1f6b03b290ca2dd66

and then

http://git.kernel.org/tip/9387f774d61b01ab71bade85e6d0bfab0b3419bd

We would very much like these patches to get into 11.10. As soon as
kernel.org is revived, please consider integrating them.
