[0/5] powerpc64/bpf: jit support for cpuv4 instructions

Message

Artem Savkov May 17, 2024, 7:56 a.m. UTC

Add support for recently added cpuv4 instructions fixing test_bpf module
failures. This is mostly based on 8ecf3c1dab1c6 (powerpc/bpf/32: Fix
failing test_bpf tests, 2024-03-05)

Artem Savkov (5):
  powerpc64/bpf: jit support for 32bit offset jmp instruction
  powerpc64/bpf: jit support for unconditional byte swap
  powerpc64/bpf: jit support for sign extended load
  powerpc64/bpf: jit support for sign extended mov
  powerpc64/bpf: jit support for signed division and modulo
