Hello Paul,

Your feedback is really appreciated. I have started with testing the 
four attached patches. With the tests I ran so far these patches were 
sufficient to avoid any soft lockup or RCU stall complaints. I will 
submit these patches to the appropriate maintainers once I have finished 
testing these patches.

Bart.
