riscv: Fix auipc+jalr relocation range checks (2022-03-10 20:37:44 -0800)
---------------------------------------------------------------- RISC-V Fixes for 5.17-rc8
* A fix to prevent users from enabling the alternatives framework (and thus errata handling) on XIP kernels, where runtime code patching does not function correctly. * A fix to properly detect offset overflow for AUIPC-based relocations in modules. This may manifest as modules calling arbitrary invalid addresses, depending on the address allocated when a module is loaded.
---------------------------------------------------------------- I know it's pretty late, so no big deal if these don't make it for 5.17.
The module issue is particularly ugly: itcould manifest for the majority of users, and depends on a bunch of long-term runtime behavior so won't get caught by simple tests. The bug has been around forever, though, and it'll likely get backported either way -- figured there's no reason to wait, though.
