3.16.7-ckt20 -stable review patch. If anyone has any objections, please let me know. ------------------ From: Ilia Mirkin <imirkin@xxxxxxxxxxxx> commit 2a6c521bb41ce862e43db46f52e7681d33e8d771 upstream. On nv50+, we restrict the valid domains to just the one where the buffer was originally created. However after the buffer is evicted to system memory, we might move it back to a different domain that was not originally valid. When sharing the buffer and retrieving its GEM_INFO data, we still want the domain that will be valid for this buffer in a pushbuf, not the one where it currently happens to be. This resolves fdo#92504 and several others. These are due to suspend evicting all buffers, making it more likely that they temporarily end up in the wrong place.
