Or possibly find an _older_ version of the code; it doesn't seem impossible that this module might have been updated for kernel changes which are more recent than what's in kernel 3.18.21. In fact, that seems reasonably likely. I have headers for 4.0.0-2, 4.1.0-1, and 4.1.0-2 installed, and they all define drm_local_map_t in include/drm/drm_legacy.h; if kernel 3.18.21 defines it elsewhere (such that the includes in this module don't find it) or doesn't define it, that would explain the observed behavior. Unfortunately I don't have immediate access to a set of headers for the 3.18-era kernel, so I can't easily check that myself, but it shouldn't be hard for you to check it on your build machine. -- The Wanderer The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself.
