drm/i810: remove the BKL
SMP i810 systems were practically nonexistent and the configuration was not officially supported by Intel at the time when Pentium-III was common. With this change, it is still possible to build a distribution kernel that has support for SMP and includes the i810 driver without the BKL. As a precaution, check for the theoretical SMP case at run time and refuse to load the driver. We also need to disable CONFIG_PREEMPT builds for this driver.

Choose this option if you have an Intel I810 graphics card. If M is
selected, the module will be called i810. AGP support is required
