Subject: [PATCH 2/9] vmlinux.lds.h: Add .gnu.version* to DISCARDS
Date: Thu, 27 Feb 2020 16:22:37 -0800	[thread overview]
Message-ID: <20200228002244.15240-3-keescook@chromium.org> (raw)
In-Reply-To: <20200228002244.15240-1-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.
