From c60afe1014dc4b8d2211fb6cc9dd08ebab31d00b Mon Sep 17 00:00:00 2001 From: Riku Voipio Date: Fri, 28 Mar 2008 13:08:09 +0100 Subject: [ARM] 4878/1: Add oabi shim for fstatat64 Ccoreutils and other have started using fstatat64. Thus, we need a shim for it if we want to support modern oldabi userlands (such as Debian/arm/lenny) with EABI kernels.
