Hello Sascha,

please drop this patch from all your stable-series queues....
It shouldn't be backported.

I've dropped it, but... why?
It exposed a problem in the kernel flush code for PA 1.x machines. The patch works okay on
all PA 2.0 machines.  It also works on PA 1.x machines when flush_cache_all is used to flush
changes to memory.

Helge is investigating PA 1.x problem.
