Subject: [PATCH v1 0/7] Module relocation fixes and asm/insn.h header
Date: Mon, 31 Jan 2022 19:21:38 +0100 [thread overview]
Message-ID: <20220131182145.236005-1-kernel@esmil.dk> (raw)
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
