Some boards seem to have garbage in the upper 16 bits of the vram size register. Check for this and clamp the size properly. Fixes boards reporting bogus amounts of vram.

drm/i915: Fix pipe CSC post offset calculation 2013-12-20T15:45:09+00:00 Ville Syrjälä ville.syrjala@linux.intel.com 2013-11-28T20:10:38+00:00 a07e39486b2d0a6e15e134501f7e38b1bcfac07c commit 32cf0cb0294814cb1ee5d8727e9aac0e9aa80d2e upstream. We were miscalculating the pipe CSC post offset for the full->limited range conversion. The resulting post offset was double what it was supposed to be, which caused blacks to come out grey when using limited range output on HSW+.

drm/radeon/audio: correct ACR table 2013-12-08T15:29:28+00:00 Pierre Ossman pierre@ossman.eu 2013-11-06T19:00:32+00:00 84a0264e3992db6dd46d4485e171a13be4550d0c commit 3e71985f2439d8c4090dc2820e497e6f3d72dcff upstream.
