Subject: [PATCH 4.9 31/83] xtensa: add NOTES section to the linker script

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

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

From: Max Filippov <jcmvbkbc@...il.com>

commit 4119ba211bc4f1bf638f41e50b7a0f329f58aa16 upstream.

This section collects all source .note.* sections together in the
vmlinux image. Without it .note.Linux section may be placed at address
0, while the rest of the kernel is at its normal address, resulting in a
huge vmlinux.bin image that may not be linked into the xtensa Image.elf.
