Subject: [PATCH v5 06/12] genksyms: adjust the output format to modpost
Date:   Thu, 12 May 2022 01:45:08 +0900
Message-Id: <20220511164514.2741934-7-masahiroy@kernel.org>

Make genksyms output symbol versions in the format modpost expects,
so the 'sed' is unneeded.

This commit makes *.symversions completely unneeded.

I will keep *.symversions in .gitignore and 'make clean' for a while.
Otherwise, 'git status' might be surprising.
