So for a quick fix, you could revert just the changes to lib/Kconfig and all the defconfigs. That way all the UNUSED_SYMBOLS infrastructure is still removed, but TRIM_UNUSED_KSYMS remains (un)set whenever it used to be (un)set and that could then be cleaned up in a followup patch set per architecture when we know it works. --=20 Cheers, Stephen Rothwell --Sig_/Ve2Gj7CFwA6nEqZCIcPGXRm Content-Type: application/pgp-signature Content-Description: OpenPGP digital signature -----BEGIN PGP SIGNATURE----- iQEzBAEBCAAdFiEENIC96giZ81tWdLgKAVBC80lX0GwFAmAjz9wACgkQAVBC80lX 0Gz/Dgf/XjojqFPVsjOyBJyhznHqyo9BVhsUryG4Aozj8T4HwoNf8rANih8uPv6/ bkvYyBj8N1I0O5hwImdJ25x0ZQJ8lFtD4TA6+F9XaKPV3IfSewRc4L2bVWFiWMoO 66AeJwFy4xD93HcfqXxMv5fVMeZ9q7idOihUt+gbU+18tHQzuYdMfO12guPUg0EK 3c7WxlZ8HnapQXeUCZvJ74Hmw5WsdZ0zWNuiDyqrIhHpPgZxUhRmUgzKr/GQUCfq f1ODmOYOh4MJnyWKkrWAI68LZEDB009fGESxMh6DJcGDH8OUiL6If2Dog7Dw8Br4 /wCH9E2NLeLbcFIv0H5cwFayqmrJ8g== =h6Kn -----END PGP SIGNATURE----- --Sig_/Ve2Gj7CFwA6nEqZCIcPGXRm--
