The following commit has been merged into the x86/build branch of tip: Commit-ID: c9174047b48d700a785b633319dd7d27288b86be Gitweb: https://git.kernel.org/tip/c9174047b48d700a785b633319dd7d27288b86be Author: Kees Cook <keescook@xxxxxxxxxxxx> AuthorDate: Tue, 29 Oct 2019 14:13:35 -07:00 Committer: Borislav Petkov <bp@xxxxxxx> CommitterDate: Mon, 04 Nov 2019 15:57:41 +01:00 vmlinux.lds.h: Replace RW_DATA_SECTION with RW_DATA Rename RW_DATA_SECTION to RW_DATA. (Calling this a "section" is a lie, since it's multiple sections and section flags cannot be applied to the macro.)
