Merge branch 'hot-fixes' (fixes for rc6)
This is a collection of three fixes for small annoyances. Two of these are already pending in other trees, but I really don't want to release another -rc with these issues pending, so I picked up the patches for these things directly. We'll end up with duplicate commits eventually, I prefer that over having these issues pending. The third one is just me getting rid of another BUG_ON() just because it was reported and I dislike those things so much. * merge 'hot-fixes' branch: ida: don't use BUG_ON() for debugging drm/aperture: Run fbdev removal before internal helpers ptrace: fix clearing of JOBCTL_TRACED in ptrace_unfreeze_traced()
