Subject: [PATCH 4.4 153/210] scripts/gdb: account for changes in module data structure

4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Jan Kiszka <jan.kiszka@...mens.com>

commit ad4db3b24a93e52a92ad8f9b0273a9416f202c23 upstream.

Commit 7523e4dc5057 ("module: use a structure to encapsulate layout.")
factored out the module_layout structure.  Adjust the symbol loader and
the lsmod command to this.
