Subject: OOM with hackbench against next 0708

While executing hackbench against today's next on a 4 way
power6 box (9117 MMA), the machine crawled within few seconds
with lots of OOM messages. I captured a Crash dump and was
able to extract the dmesg log which i have attached here.

This problem started with 0706 next release. 0703 worked fine.

Kernel is compiled with SLQB and 64K page size.

.config attached. Let me know what other information i can
provide to find a solution for this problem.

Thanks
-Sachin
