Subject: [PATCH v2 0/7] Module relocation fixes and asm/insn.h header
Date: Mon, 31 Jan 2022 19:27:13 +0100	[thread overview]
Message-ID: <20220131182720.236065-1-kernel@esmil.dk> (raw)

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.

/Emil

  riscv: Remove unneeded definitions from asm/module.h
  riscv: Avoid unaligned access when relocating modules
  riscv: Fix auipc+jalr relocation range checks
  riscv: Add asm/insn.h header
  riscv: Use asm/insn.h for module relocations
  riscv: Use asm/insn.h to generate plt entries
  riscv: Use asm/insn.h for jump labels
