The preceding commits add s390 64-bit (s390x) support in binutils to
generate SFrame stack trace information (.sframe section) in the
assembler from CFI directives (with option --gsframe), generate .sframe
section for linker-generated .plt section in the linker, and dump SFrame
information in objdump and readelf (with option --sframe).

binutils/
	* NEWS: Announce s390 64-bit (s390x) SFrame V2 support in
	as, ld, objdump, and readelf.

gas/
	* NEWS: Update s390 64-bit (s390x) SFrame V2 support in
	assembler.

+* On s390 64-bit (s390x), gas, ld, objdump, and readelf now support generating
+  and processing SFrame V2 stack trace information (.sframe).  The assembler
+  generates SFrame info from CFI directives with option "--gsframe".  The
+  linker generates SFrame info for the linker-generated .plt section and merges
+  all .sframe sections.  Both objdump and readelf dump SFrame info with option
+  "--sframe[=<section-name>]".

 * For SFrame stack trace format, the function start address in each SFrame
   FDE has a changed encoding:  The 32-bit signed integer now holds the offset
   of the start PC of the associated function from the sfde_func_start_address
