[PATCH bpf-next] Enable zext optimization for more RV64G ALU ops

2019-07-04 Thread Luke Nelson
commit 66d0d5a854a6 ("riscv: bpf: eliminate zero extension code-gen") added the new zero-extension optimization for some BPF ALU operations. Since then, bugs in the JIT that have been fixed in the bpf tree require this optimization to be added to other operations: commit 1e692f09e091 ("bpf, riscv:
