From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx> Mesa changed its clear color alignment without informing the kernel, and now the kernel expects 4k alignment whereas Mesa only guaratees 64 bytes. Reduce the kernel alignment requirement to the same 64 bytes since there's no real reason for the current 4k limit. And while at it add some missing checks and debugs to the clear color hadling.
