commit a4a98791f6659a59f26142b72298fc964faaf074
Author: Mark Wielaard <mjw@redhat.com>
Date:   Thu Sep 8 17:22:25 2011 +0200

    Remove commented out and outdated (confusing embedded C) example from SBG.
    
    Just remove so there are no false positives while looking for dangerous
    embedded C snippets. The actual example just includes the thread-times.stp
    file which is fine.

commit 74a633228edc34e14121cec237ec447402178186

    Don't try to be smart detecting perf event was in user mode.
    
    Just use user_mode(regs) always.
    Add test to check we always detect some user_mode activity.

commit 92c25572b09ea782ec9d0ce634531923ce945c04
Author: Mark Wielaard <mjw@redhat.com>
Date:   Thu Sep 8 13:57:21 2011 +0200

    Rename CONTEXT regflags to probe_flags. Now simply indicates user mode.
    
    Renamed common_probe_context.h regflags to probe_flags, rename constant
    from _STP_REGS_USER_FLAG to _STP_PROBE_STATE_USER_MODE and use throughout
    tapsets to check whether in user_mode() or not.
