[TESTCASE] * Boot with a GF119 and set resolution set to 1680x1050 with xrandr, then try to move some window past the end of the screen. This should cause a crash, or maybe the first part is already sufficient. [Regression Potential] The change is localized to NVRefreshArea, so unlikely to cause many regressions. However some other fixes are SRU'd too, so as a whole we should watch for any new bug reports with nouveau during the proposed stage. [Other Info] After I found the commit fixing the issue, it was very issue for me to reproduce based on how it fixes it. The bug only happens on specific resolutions due to how memory is managed.
