[POWERPC] spufs: handle faults while the context switch pending flag is set
Currently, page fault handlers don't issue a mfc restart if the context switch pending flag is set, which can leave us with a hanging DMA after a context restore. This patch introduces fault pending flag that is set by the fault handler and read by the context switch code, so that the latter can add the restart bit at the right spot, after it has successfuly saved the state of the mfc control register.
