From 1c182a628075af7431edb8155601740867b5ae51 Mon Sep 17 00:00:00 2001 From: Martin Schwidefsky Date: Tue, 3 Dec 2013 11:09:10 +0100 Subject: [PATCH] s390/ptrace: simplify enable/disable single step The user_enable_single_step() and user_disable_sindle_step() functions are always called on the inferior, never for the currently active process. Remove the unnecessary check for the current process and the update_cr_regs() call from the enable/disable functions.
