      "message": "net: filter: BPF \u0027JIT\u0027 compiler for PPC64\n\nAn implementation of a code generator for BPF programs to speed up packet\nfiltering on PPC64, inspired by Eric Dumazet\u0027s x86-64 version.\n\nFilter code is generated as an ABI-compliant function in module_alloc()\u0027d mem\nwith stackframe \u0026 prologue/epilogue generated if required (simple filters don\u0027t\nneed anything more than an li/blr).  The filter\u0027s local variables, M[], live in\nregisters.  Supports all BPF opcodes, although \"complicated\" loads from negative\npacket offsets (e.g. SKF_LL_OFF) are not yet supported.\n\nThere are a couple of further optimisations left for future work; many-pass\nassembly with branch-reach reduction and a register allocator to push M[]\nvariables into volatile registers would improve the code quality further.\n\nThis currently supports big-endian 64-bit PowerPC only (but is fairly simple\nto port to PPC32 or LE!).\n\nEnabled in the same way as x86-64:\n\n\techo 1 \u003e /proc/sys/net/core/bpf_jit_enable\n\nOr, enabled with extra debug output:\n\n\techo 2 \u003e /proc/sys/net/core/bpf_jit_enable\n\nSigned-off-by: Matt Evans \u003cmatt@ozlabs.org\u003e\nAcked-by: Eric Dumazet \u003ceric.dumazet@gmail.com\u003e\nSigned-off-by: David S.
