[0/3] RISC-V: Fix sparse warnings

Message

After the steal-time series was merged, LKP sent me mail with sparse
warnings for the lack of using appropriate restricted types and a
local variable not being static. This series makes the fixups
necessary to appease sparse for 64-bit compiles. Changes to
__get_user_8() and __put_user_8() are needed to completely quiet
sparse for 32-bit compiles. I'll address those 32-bit sparse warnings
separately, since it's not 100% clear how best to approach a couple of
them.

Thanks,
drew

Queued this series as fixes for Linux-6.8
