Subject: [PATCH v2 00/10] gpu: nova-core: miscellaneous improvements

A few simple, loosely-related small improvements for nova-core,
including reporting unprocessed data in GSP messages, removal of
unnecessary code in GSP and the sequencer, and leveraging the Zeroable
derive macro and core library's CStr. Probably nothing too
controversial.

This series is based on the fixup patch series for this cycle [1].
