Hi All,

Just getting back into Cell after a while working on other projects.
Started on a scheduler defect, but noticed several bugs which I have
crept in.  This fixes those bugs and the test case problem also. 

patch 1 is a fix to an earlier patch from christoph hellwig regarding
making the context lock an interruptible mutex lock.  

patch 2 fixes a premature exit from spufs_run_spu that was observed in
the failing testcase.

patch 3 fixes a starvation case also observed in the failing testcase.

patch 4 fixes a statistic updating problem that dates back to my
scheduler changes.  I think.

patch 5 fixes a problem with andre's restart dma patch and implements it
in a more platform and hardware independent way.  

With these fixes, I believe that I can start on gang scheduling.

Are these too late for 2.6.25?

Cheers,
Luke
