From ce65a44de07f73ceda1749812b75086b7add408d Mon Sep 17 00:00:00 2001 From: Thomas Hellstrom Date: Mon, 7 Aug 2006 22:03:22 +1000 Subject: [PATCH] drm: add drm simple memory manager support for SiS and VIA drivers This add support to the SiS and VIA drivers for the simple memory manager. This fixes a lot of problems with the current simple code these drivers used, including locking and SMP issues.
