3.5.7.2 -stable review patch. If anyone has any objections, please let me know.
------------------ From: Tom Herbert <[email protected]> commit baefa31db2f2b13a05d1b81bdf2d20d487f58b0a upstream. In commit c445477d74ab3779 which adds aRFS to the kernel, the CPU selected for RFS is not set correctly when CPU is changing. This is causing OOO packets and probably other issues.
