Hi all, So I hoped to get through more drivers, but it's not yet all of them. Anyway, this gets rid of dev->struct_mutex in a lot more places. Big thing is that core gem is now completely struct_mutex free, the only reason we still lock it is that some drivers need it in their ->free_gem_object hook. The plan for that is to have a ->free_gem_object_unlocked hook for all the drivers which don't need the lock at all (which are most of them really). Of the modern drivers the big holdouts are i915, msm and omapdrm. Plus udl still uses some struct_mutex, but it has overall totally broken locking anyway. All other drivers are now struct_mutex free, yay! All per-driver bits are fully independent in this series, so can be pulled into driver trees without issues.
