Pu Lehui adebac5995 riscv, bpf: Emit fixed-length instructions for BPF_PSEUDO_FUNC ... [ Upstream commit b54b600361 ] For BPF_PSEUDO_FUNC instruction, verifier will refill imm with correct addresses of bpf_calls and then run last pass of JIT. Since the emit_imm of RV64 is variable-length, which will emit appropriate length instructions accorroding to the imm, it may broke ctx->offset, and lead to unpredictable problem, such as inaccurate jump. So let's fix it with fixed-length instructions.
