Changes since v1: - Add missing else condition in ltc - Remove extra flags that slipped into nouveau_display.c and nv84_fence.c. Original cover letter: Patches 1-3 make the presence of a RAM device optional, and remove GK20A's dummy RAM driver we were using so far. On chips using shared memory, such a device can confuse the driver into moving objects where there is no need to, and can trick

A series I have waited too long to submit, and the recent refactoring made me pay the price of my perfectionism, so here are the features that are at least completed Patches 1-3 make the presence of a RAM device optional, and remove GK20A's dummy RAM driver we were using so far.
