From ac49b9a9f26b6c42585f87857722085ef4b19c13 Mon Sep 17 00:00:00 2001 From: Andy Lutomirski Date: Mon, 19 May 2014 15:58:34 -0700 Subject: x86, mm: Replace arch_vma_name with vm_ops->name for vsyscalls This removes the last vestiges of arch_vma_name from x86, replacing it with vm_ops->name. Good riddance. Signed-off-by: Andy Lutomirski Link: http://lkml.kernel.org/r/e681cb56096eee5b8b8767093a4f6fb82839f0a4.1400538962.git.luto@amacapital.net Signed-off-by: H.
