We are pleased to announce the next update to our new preempt-rt series.

- update to 2.6.31-rc6

- ARM updates (Uwe Kleine-Koenig)

- OF fixes

- threaded interrupt crash fix (Linus)

- locking build fix

- minor fixes all over the place

There is a known boot problem on PSeries machines which is still investigated by Will. If you have access to such a beast please help to get this decoded.

I have not merged one of the proposed fixed for the ARM highmem problem. We really want someone with such a hardware to have a look and confirm the fix.
