[PATCH 3/4] uprobes/x86: Cleanup the single-stepping code

2012-10-28 Thread Oleg Nesterov
No functional changes. Now that default arch_uprobe_enable/disable_step() helpers do nothing, x86 has no reason to reimplement them. Change arch_uprobe_*_xol() hooks to do the necessary work and remove the x86-specific hooks. Signed-off-by: Oleg Nesterov --- arch/x86/kernel/uprobes.c | 54 +++
