From 7ffa05e0518ebc055ef8f68d7d53e5f7d2ba3428 Mon Sep 17 00:00:00 2001 From: Ian Romanick Date: Thu, 22 Nov 2007 17:02:08 +1000 Subject: drm: Fix ioc32 compat layer Previously any ioctls that weren't explicitly listed in the compat ioctl table would fail with ENOTTY. If the incoming ioctl number is outside the range of the table, assume that it Just Works, and pass it off to drm_ioctl. This make the fence related ioctls work on 64-bit PowerPC.
