Eric Anholt 955a23eb3c drm: Use a little stash on the stack to avoid kmalloc in most DRM ioctls. ... The kmalloc was taking up about 1.5% of the CPU on an ioctl-heavy workload (x11perf -aa10text on 965). Initial results look like they have a corresponding improvement in performance for aa10text, but more numbers might not hurt. Thanks to ajax for pointing out this performance regression I'd introduced back in 2007.
