MIPS: ptrace: Fix regs_return_value for kernel context
Currently regs_return_value always negates reg[2] if it determines the syscall has failed, but when called in kernel context this check is invalid and may result in returning a wrong value. This fixes errors reported by CONFIG_KPROBES_SANITY_TEST Fixes: d7e7528bcd45 ("Audit: push audit success and retcode into arch ptrace.h") Signed-off-by: Marcin Nowakowski <marcin.nowakowski@imgtec.com> Cc: linux-mips@linux-mips.org Cc: stable@vger.kernel.org # 3.3+ Patchwork: https://patchwork.linux-mips.org/patch/14381/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
