+Subject: [PATCH] xtensa: add NOTES section to the linker script
+
+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.
