Martin Schwidefsky fc0a1fea6b [S390] kprobes: single step cleanup ... The saved interrupt mask and the saved control registers are only relevant while single stepping is set up. A secondary kprobe while kprobe single stepping is active may not occur. That makes is safe to remove the save and restore of kprobe_saved_imask / kprobe_save_ctl from save_previous_kprobe and restore_previous_kprobe. Move all single step related code to two functions, enable_singlestep and disable_singlestep. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>		2011-01-05 12:47:23 +01:00
