[Hardy] SRU: MSI-X allocation leakage

[Stefan Bader]

https://bugs.edge.launchpad.net/ubuntu/+source/linux/+bug/273103

SRU justification:

Impact: After several unload/load cycles the resources for MSI(-X) interrupts
cannot be allocated anymore and drivers will have to fall back to legacy
interrupts.

Fix: Patch from 2.6.24.y stable tree to update the allocation bitmap on unload.

Testcase: Unload and load a driver module that uses MSI(-X) interrupts on
hardware that supports it. After a while error messages will indicate that the
driver had to fallback to legacy interrupts (without patch)

When all other means of communication fail, try words!
