David reported them with the toolchains I built at https://mirrors.edge.kernel.org/pub/tools/crosstool/ I'm fairly sure the problem is specific to the .config and tree, not the toolchain though. >>> or (alpha) >>> >>> WARNING: modpost: "saved_config" [vmlinux] is COMMON symbol >>> ERROR: modpost: "memcpy" [fs/reiserfs/reiserfs.ko] undefined! >>> ERROR: modpost: "memcpy" [fs/nfs/nfs.ko] undefined! >>> ERROR: modpost: "memcpy" [fs/nfs/nfsv3.ko] undefined! >>> ERROR: modpost: "memcpy" [fs/nfsd/nfsd.ko] undefined! >>> ERROR: modpost: "memcpy" [fs/lockd/lockd.ko] undefined! >>> ERROR: modpost: "memcpy" [crypto/crypto.ko] undefined! >>> ERROR: modpost: "memcpy" [crypto/crypto_algapi.ko] undefined! >>> ERROR: modpost: "memcpy" [crypto/aead.ko] undefined! >>> ERROR: modpost: "memcpy" [crypto/crypto_skcipher.ko] undefined! >>> ERROR: modpost: "memcpy" [crypto/seqiv.ko] undefined! > > Are these from ARC build or otherwise ?
