drm/nouveau/vm: reduce number of entry-points to vm_map() Pretty much everywhere had to make the decision which to use, so it makes a lot more sense to just have one entrypoint decide the path to take instead. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

drm/nouveau: use vmalloc for pgt allocation Page tables on nv50 take 48kB, which can be hard to allocate in one piece. Let's use vmalloc. Signed-off-by: Marcin Slusarz <marcin.slusarz@gmail.com> Cc: stable@vger.kernel.org [3.7+] Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

drm/nouveau/vm: take subdev mutex, not the mm, protects against race with vm/nvc0 nvc0_vm_flush() accesses the pgd list, which will soon be able to race with vm_unlink() during channel destruction. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

drm/nouveau/vm: fix memory corruption when pgt allocation fails If we return freed vm, nouveau_drm_open will happily call nouveau_cli_destroy, which will try to free it again.

drm/nouveau: port all engines to new engine module format This is a HUGE commit, but it's not nearly as bad as it looks - any problems can be isolated to a particular chipset and engine combination. It was simply too difficult to port each one at a time, the compat layers are *already* ridiculous. Most of the changes here are simply to the glue, the process for each of the engine modules was to start with a standard skeleton and copy+paste the old code into the appropriate places, fixing up variable names etc as needed. v2: Marcin Slusarz <marcin.slusarz@gmail.com> - fix find/replace bug in license header v3: Ben Skeggs <bskeggs@redhat.com> - bump indirect pushbuf size to 8KiB, 4KiB barely enough for userspace and left no space for kernel's requirements during GEM pushbuf submission. - fix duplicate assignments noticed by clang v4: Marcin Slusarz <marcin.slusarz@gmail.com> - add sparse annotations to nv04_fifo_pause/nv04_fifo_start - use ioread32_native/iowrite32_native for fifo control registers v5: Ben Skeggs <bskeggs@redhat.com> - rebase on v3.6-rc4, modified to keep copy engine fix intact - nv10/fence: unmap fence bo before destroying - fixed fermi regression when using nvidia gr fuc - fixed typo in supported dma_mask checking Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

drm/nouveau: restructure source tree, split core from drm implementation Future work will be headed in the way of separating the policy supplied by the nouveau drm module from the mechanisms provided by the driver core. There will be a couple of major classes (subdev, engine) of driver modules that have clearly defined tasks, and the further directory structure change is to reflect this. No code changes here whatsoever, aside from fixing up a couple of include file pathnames. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
