Thanks here's an updated version with a couple more bugs fixed. If
you could try testing, that would be much appreciated.

Feel free to add my Tested-by:

Like wise - 16 hours of clean run with the latest

Thanks for all the hard work everyone put into this one, great to

No more RCU stalls on PowerPC, system is clean when idle or with some
test runs.

Thank you all for your time and efforts in fixing this.
