Merge patch series "riscv: Dump faulting instructions in oops handler"
Björn Töpel <bjorn@kernel.org> says:
From: Björn Töpel <bjorn@rivosinc.com>
RISC-V does not dump faulting instructions in the oops handler. This
series adds "Code:" dumps to the oops output together with
scripts/decodecode support.
* b4-shazam-merge:
scripts/decodecode: Add support for RISC-V
riscv: Add instruction dump to RISC-V splats
