With kms all the data getparam looks at is actually invariant, and certainly not protected by the global kms mutex. With ums all the setup code is already racy as hell, so this won't make things any worse.

Correct.

I've done this change so that all ioctl still used by kms drivers are marked as DRM_UNLOCKED, besides that we obviously don't need it any more in kms mode.
