Sebastian Andrzej Siewior 9d77878226 uprobes: Introduce arch_uprobe_enable/disable_step() ... As Oleg pointed out in [0] uprobe should not use the ptrace interface for enabling/disabling single stepping. [0] http://lkml.kernel.org/r/20120730141638.GA5306@redhat.com Add the new "__weak arch" helpers which simply call user_*_single_step() as a preparation. This is only needed to not break the powerpc port, we will fold this logic into arch_uprobe_pre/post_xol() hooks later. We should also change handle_singlestep(), _disable_step(&uprobe->arch) should be called before put_uprobe().
