Apologies! I messed up v1. Please consider this patch set only.
The first patch removes a bunch of code from the asm/module.h which is included in almost all drivers through linux/module.h. Next are two patches to fix unaligned access when doing module relocations and do proper range checks for auipc+jalr offsets.
I'm a little less confident about the following patches, so consider this more of an RFC for those. The idea is to consolidate the RISC-V instruction generation and manipulation similar to arm64's asm/insn.h header.
