MIPS: eBPF: Initial eBPF support for MIPS32 architecture.
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.
