From 93240b327929ff03c1878ea8badc5c6bd86f053f Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Tue, 29 Oct 2019 14:13:34 -0700 Subject: [PATCH] vmlinux.lds.h: Replace RO_DATA_SECTION with RO_DATA Finish renaming RO_DATA_SECTION to RO_DATA. (Calling this a "section" is a lie, since it's multiple sections and section flags cannot be applied to the macro.)
