    MIPS: eBPF: Initial eBPF support for MIPS32 architecture. · 716850ab
    Hassan Naveed authored
    Currently MIPS32 supports a JIT for classic BPF only, not extended BPF.
    This patch adds JIT support for extended BPF on MIPS32, so code is
    actually JIT'ed instead of being only interpreted. Instructions with
    64-bit operands are not supported at this point.
    We can delete classic BPF because the kernel will translate classic BPF
    programs into extended BPF and JIT them, eliminating the need for
    classic BPF.
