	Backport from mainline
	2012-03-09  Michael Meissner  <meissner@linux.vnet.ibm.com>

	* config/rs6000/linux64.h (OPTION_TARGET_CPU_DEFAULT): Do not
	redefine to be NULL if the current bit-size is different from the
	configured bit-size.

	* config/rs6000/rs6000.c (rs6000_option_override_internal): If the
	cpu is defaulted, use PROCESSOR_DEFAULT and PROCESSOR_DEFAULT64 to
	set the default tuning.  Add asserts to make sure the cpu and tune
	indexes are defined.  Fix tests for cpu/tune index to use >= 0 to
	test whether the index is set, instead of > 0.
	(rs6000_file_start): Do not reset the default cpu if the current
	bit-size is different from the configured bit-size.
