I improved a few things, most notably I fixed a stack overflow. Other
than that the following changes are included, too:

 - update to 3.3-rc3
 - only check bit 3 of lr to determine which mode the machine was in
   when the current exception triggered
 - several updates to the efm32 platform (that should IMHO only go in
   when the M3 support is available in mainline)

I'd be really happy to get some feedback on Catalin's and my patches and
will repost the patches I think are mature enough to go in for a start.

The updated and complete stack is available from the URLs above.

Best regards
Uwe
