	* NEWS (New commands): Mention "set disable-randomization".
	* configure.ac: Add check for HAVE_PERSONALITY and
	HAVE_DECL_ADDR_NO_RANDOMIZE.
	* configure, config.in: Regenerate.
	* linux-nat.c [HAVE_PERSONALITY]: New include <sys/personality.h>.
	[HAVE_PERSONALITY] [!HAVE_DECL_ADDR_NO_RANDOMIZE]: Set
	ADDR_NO_RANDOMIZE.
	(disable_randomization, show_disable_randomization)
	(set_disable_randomization): New.
	(linux_nat_create_inferior) [HAVE_PERSONALITY]: New variables
	PERSONALITY_ORIG and PERSONALITY_SET.  Disable randomization upon the
	variable DISABLE_RANDOMIZATION.
	(_initialize_linux_nat): Call ADD_SETSHOW_BOOLEAN_CMD for the variable
	DISABLE_RANDOMIZATION.

gdb/doc/
	* gdb.texinfo (Starting): Document "set disable-randomization".

gdb/testsuite/
