From e048d004a5392e3d6d78b0a53335391f87d724ec Mon Sep 17 00:00:00 2001 From: Catalin Marinas Date: Wed, 3 Oct 2012 11:20:20 +0100 Subject: [PATCH] arm64: Use the generic compat_sys_sendfile() implementation The generic implementation of compat_sys_sendfile() has been introduced by commit 8f9c0119. This patch removes the arm64 implementation in favour of the generic one.
