RISC-V: Make our port sparse-clean
This patch set contains a handful of fixes that clean up the sparse
results for the RISC-V port. These patches shouldn't have any
functional difference. The patches:
* Use NULL instead of 0.
* Clean up __user annotations.
* Split __copy_user into two functions, to make the __user annotations
valid.
