	* sysdeps/generic/segfault.c (struct layout): Delete definition;
	include the above file instead.
	* sysdeps/generic/backtrace.c (struct layout): Likewise.
	(__backtrace): Use ADVANCE_STACK_FRAME.
	* sysdeps/unix/sysv/linux/arm/sigcontextinfo.h
	(ADVANCE_STACK_FRAME): New macro.
	(GET_FRAME): Apply above to returned value.

	* sysdeps/unix/sysv/linux/arm/bits/armsigctx.h: Add `fault_address'.
