Subject: [PATCH v2 1/3] vmlinux.lds.h: Add .gnu.version* to DISCARDS
Date: Mon, 22 Jun 2020 13:53:39 -0700
Message-ID: <20200622205341.2987797-2-keescook@chromium.org> (raw)
In-Reply-To: <20200622205341.2987797-1-keescook@chromium.org>

For vmlinux linking, no architecture uses the .gnu.version* section,
so remove it via the common DISCARDS macro in preparation for adding
--orphan-handling=warn more widely.
