[POWERPC] spufs: rework class 0 and 1 interrupt handling
Based on original patches from Arnd Bergmann <arnd.bergman@de.ibm.com>; and Luke Browning <lukebr@linux.vnet.ibm.com> Currently, spu contexts need to be loaded to the SPU in order to take class 0 and class 1 exceptions. This change makes the actual interrupt-handlers much simpler (ie, set the exception information in the context save area), and defers the handling code to the spufs_handle_class[01] functions, called from spufs_run_spu. This should improve the concurrency of the spu scheduling leading to greater SPU utilization when SPUs are overcommited.
