So when the patch gets applied the address will point to the wrong location. So similar to arm64 the target addresses need to be updated. This is probably also helpful for other things needing more complex code in alternatives. For v2 I got into some sort of cleanup spree for the general instruction parsing that already existed. A number of places do their own instruction parsing and I tried consolidating some of them. Noteable, the kvm parts still do, but I had to stop somewhere :-) * b4-shazam-merge: RISC-V: fix auipc-jalr addresses in patched alternatives RISC-V: add helpers for handling immediates in U-type and I-type pairs RISC-V: add rd reg parsing to insn.h header RISC-V: add U-type imm parsing to insn.h header RISC-V: kprobes: use central defined funct3 constants RISC-V: rename parse_asm.h to insn.h RISC-V: Move riscv_insn_is_* macros into a common header RISC-V: add auipc elements to parse_asm header RISC-V: add ebreak instructions to definitions RISC-V: detach funct-values from their offset RISC-V: add prefix to all constants/macros in parse_asm.h RISC-V: fix funct4 definition for c.jalr in parse_asm.h Link: https://lore.kernel.org/r/20221223221332.4127602-1-heiko@sntech.de Signed-off-by: Palmer Dabbelt --- b07de94d4501c61a3015cb0035227e449c51d87e
