2018-12-05drm/vmwgfx: Fix a layout race conditionThomas Hellstrom
This fixes a layout update race condition. We make sure the crtc mutex is locked before we dereference crtc->state. Otherwise the state might change under us. Since now we're already holding the crtc mutexes when reading the gui coordinates, protect them with the crtc mutexes rather than with the requested_layout mutex.

2018-09-27drm/vmwgfx: Look up objects without taking a referenceThomas Hellstrom
Typically when we look up objects under the rcu lock, we take a reference to make sure the returned object pointer is valid. Now provide a function to look up an object and instead of taking a reference to it, keep the rcu lock held when returning the object pointer. This means that the object pointer is valid as long as the rcu lock is held, but the object may be doomed (its refcount may be zero). Any persistent usage of the object pointer outside of the rcu lock requires a reference to be taken using kref_get_unless_zero().

2018-09-27drm/vmwgfx: Make the object handles idr-generatedThomas Hellstrom
Instead of generating user-space object handles based on a, possibly processed, hash of the kernel address of the object, use idr to generate and lookup those handles. This might improve somewhat on security since we loose all connections to the object's kernel address. Also idr is designed to do just this. As a todo-item, since user-space handles are now generated in sequence, we can probably use a much simpler hash function to hash them.

2018-09-27drm/vmwgfx: Remove the resource avail fieldThomas Hellstrom
This field was previously used to prevent a lookup of a resource before its constructor had run to its end. This was mainly intended for an interface that is now removed that allowed looking up a resource by its device id. Currently all affected resources are added to the lookup mechanism (its TTM prime object is initialized) late in the constructor where it's OK to look up the resource. This means we can change the device resource_lock to an ordinary spinlock instead of an rwlock and remove a locking sequence during lookup.

So provide a simple unprotected stack-like allocator from which these objects can be allocated. Their memory is freed with the validation context when the command submission is done.
