From f77d390c9779c496aa5b99ec832996fb76bb1d13 Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt Date: Mon, 2 Feb 2009 16:55:46 +1100 Subject: drm: Split drm_map and drm_local_map Once upon a time, the DRM made the distinction between the drm_map data structure exchanged with user space and the drm_local_map used in the kernel. 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.
