From 55436c91652b45be576b91ec96a8d65f6b7447fa Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Wed, 10 Mar 2010 15:22:55 -0800 Subject: [PATCH] mips: use generic ptrace_resume code Use the generic ptrace_resume code for PTRACE_SYSCALL, PTRACE_CONT and PTRACE_KILL. Also the TIF_SYSCALL_TRACE thread flag is now cleared on PTRACE_KILL which it previously wasn't which is consistent with all architectures using the modern ptrace code.
