Message-Id: <20071125220119.880F126F8DE@magilla.localdomain> Date: Sun, 25 Nov 2007 14:01:19 -0800 (PST) Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Content-Length: 2562 Lines: 77 This removes the handling for PTRACE_CONT et al from the 64-bit ptrace code, so it uses the new generic code via ptrace_request.
