Hi all,

This patchset contains a series of important fixes to various problems,
including lockups, crashes, screen gliches, and missing video modes.
These patches are crucial to the correct operation to the hardware,
especially Lynx3DM+ (SM720). I have tested and verified them on x86.

Please review and queue them for linux-stable.

Thanks,
