| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since the pagefault path determines that the lock order we use has to be mmap_sem -> struct_mutex, we can't allow page faults to occur while the struct_mutex is held. To fix this in pwrite, we first try optimistically to see if we can copy from user without faulting. If it fails, fall back to using get_user_pages to pin the user's memory, and map those pages atomically when copying it to the GPU.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The old mechanism to formatting proc files is extremely ugly. The seq_file API was designed specifically for cases like this and greatly simplifies the process. Also, most of the files in /proc really don't belong there. This patch introduces the infrastructure for putting these into debugfs and exposes all of the proc files in debugfs as well.

For some reasons, while the BSD port still has that "feature", the linux part abused drm_map for kernel internal usage as the local map only existed as a typedef of the struct drm_map. This patch fixes it by declaring struct drm_local_map separately (though its content is currently identical to the userspace variant), and changing the kernel code to only use that, except when it's a user<->kernel interface (ie. ioctl). This allows subsequent changes to the in-kernel format I've also replaced the use of drm_local_map_t with struct drm_local_map in a couple of places. Mostly by accident but they are the same (the former is a typedef of the later) and I have some remote plans and half finished patch to completely kill the drm_local_map_t typedef so I left those bits in.
