I applied the latest mmuops patch to a 2.6.24 kernel & updated the GRU driver to use it. As far as I can tell, everything works ok. Although more testing is needed, all current tests of driver functionality are working on both a system simulator and a hardware simulator.
The driver itself is still a few weeks from being ready to post but I can send code fragments of the portions related to mmuops or external TLB management if anyone is interested.
