Well, I've just tried to update to current master, and got system freeze
right after starting compton ( X itself
does not cause a freeze, nor does window manager (windowmaker in my case).
The freeze happens with compton. Bisecting pointed me to this commit:

    drm - Fix system lockup bug in signal_pending_state()

Prior to this change, compton runs without a problem, with this commit,
the system always freezes when compton starts. 

Also, compiler complains about unused function trap_is_smap(). I had to
comment it out for kernel compilation to succeed.
