Hi all, this little series removes the last swiotlb API exposed to modules.

Hi guys, Well let's face it AGP is a total headache to maintain and dead for at least 10+ years. We have a lot of x86 specific stuff in the architecture independent graphics memory management to get the caching right, abusing the DMA API on multiple occasions, need to distinct between AGP and driver specific page tables etc etc... So the idea here is to just go ahead and remove the support

Hi folks, Currently, when the device is removed (or the driver is unbound) the nouveau_drm structure de-allocated. However, it's still accessible from and used by some DRM layer callbacks. For example, file handles can be closed after the device has been removed (physically or otherwise). This series converts the Nouveau device structure to be allocated and de-allocated with the
