From 2ebc3cc920e7a076539aa8badbaf0919540a3438 Mon Sep 17 00:00:00 2001 From: Roland McGrath Date: Thu, 26 Jul 2007 10:41:12 -0700 Subject: [PATCH] x86_64: fix arch_vma_name The function arch_vma_name() is declared weak and thus it was not noticed that x86_64 had two almost identical implementations.
