ChangeLog:

* ppc-linux-tdep.c (ppu2spu_prev_register): Handle pseudo registers.
	(ppu2spu_unwind_register): Mark pseudo registers unavailable.
	* spu-tdep.c (op_selb): Use correct value.

testsuite/ChangeLog:

	* gdb.cell/bt.exp: Delete breakpoints before running to signal
	to avoid race condition.
	* gdb.cell/coremaker.c: Use small stack size.
	* gdb.cell/ea-standalone.exp: Use file name without path as
	argument to c_to.
	* gdb.cell/fork.exp: Allow other output when continuing to end.
