2011-12-09drm: integer overflow in drm_mode_dirtyfb_ioctl()Xi Wang
commit a5cd335165e31db9dbab636fd29895d41da55dd2 upstream. There is a potential integer overflow in drm_mode_dirtyfb_ioctl() if userspace passes in a large num_clips. The call to kmalloc would allocate a small buffer, and the call to fb->funcs->dirty may result in a memory corruption.

commit a18cee15ed4c8b6a35f96b7b26a46bac32e04bd9 upstream. Allow the user to override whether MSIs are enabled or not on supported ASICs.

I suspect this is a chipset or bios issue, but I'm not sure what the proper fix is. This will at least make diagnosing and working around the problem much easier.

commit 340764465aa4a586ca332e61ae64883e5ad6f183 upstream. Since force handling rework of d0d0a225e6ad43314c9aa7ea081f76adc5098ad4 we could end up bouncing connector status btw disconnected and unknown. When connector status change a call to output_poll_changed happen which in turn ask again for detect but with force set. So set the load detect flags whenever we report the connector as connected or unknown this avoid bouncing btw disconnected and unknown.

2011-11-11drm/i915/panel: Always record the backlight level again (but cleverly)Takashi Iwai
commit f52c619a590fa75276c07dfcaf380dee53e4ea4c upstream. The commit 47356eb67285014527a5ab87543ba1fae3d1e10a introduced a mechanism to record the backlight level only at disabling time, but it also introduced a regression. Since intel_lvds_enable() may be called without disabling (e.g. intel_lvds_commit() calls it unconditionally), the backlight gets back to the last recorded value. For example, this happens when you dim the backlight, close the lid and open the lid, then the backlight suddenly goes to the brightest. This patch fixes the bug by recording the backlight level always when changed via intel_panel_set_backlight(). And, intel_panel_{enable|disable}_backlight() call the internal function not to update the recorded level wrongly.
