From ac008fe0a3236729751ccde655c215b436dfdaeb Mon Sep 17 00:00:00 2001 From: "H. Peter Anvin" Date: Mon, 5 May 2014 15:23:35 -0700 Subject: [PATCH] x86, build: Don't get confused by local symbols arch/x86/crypto/sha1_avx2_x86_64_asm.S introduced _end as a local symbol, which broke the build under certain circumstances. Although the wisdom of _end as a local symbol can definitely be questioned, the build should not break for that reason. Thus, filter the output of nm to only get global symbols of appropriate type.
