From eaf937075c9a42eb8ba51eb3050773d7205d3595 Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Tue, 29 Oct 2019 14:13:32 -0700 Subject: vmlinux.lds.h: Move NOTES into RO_DATA The .notes section should be non-executable read-only data. As such, move it to the RO_DATA macro instead of being per-architecture defined.
