powerpc/ebpf/jit: Implement JIT compiler for extended BPF
PPC64 eBPF JIT compiler. Enable with: echo 1 > /proc/sys/net/core/bpf_jit_enable or echo 2 > /proc/sys/net/core/bpf_jit_enable ... to see the generated JIT code. This can further be processed with tools/net/bpf_jit_disasm. With CONFIG_TEST_BPF=m and 'modprobe test_bpf': test_bpf: Summary: 305 PASSED, 0 FAILED, [297/297 JIT'ed] ... on both ppc64 BE and LE. The details of the approach are documented through various comments in the code. Acked-by: Alexei Starovoitov <ast@kernel.org> Signed-off-by: Naveen N. Rao <naveen.n.rao@linux.vnet.ibm.com> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
