Nicolas Schichan 4560cdff03 ARM: net: support BPF_ALU | BPF_MOD instructions in the BPF JIT. ... For ARMv7 with UDIV instruction support, generate an UDIV instruction followed by an MLS instruction. For other ARM variants, generate code calling a C wrapper similar to the jit_udiv() function used for BPF_ALU | BPF_DIV instructions. Some performance numbers reported by the test_bpf module (the duration per filter run is reported in nanoseconds, between "jitted:<x>" and "PASS": ARMv7 QEMU nojit: test_bpf: #3 DIV_MOD_KX jited:0 2196 PASS ARMv7 QEMU jit: test_bpf: #3 DIV_MOD_KX jited:1 104 PASS ARMv5 QEMU nojit: test_bpf: #3 DIV_MOD_KX jited:0 2176 PASS ARMv5 QEMU jit: test_bpf: #3 DIV_MOD_KX jited:1 1104 PASS ARMv5 kirkwood nojit: test_bpf: #3 DIV_MOD_KX jited:0 1103 PASS ARMv5 kirkwood jit: test_bpf: #3 DIV_MOD_KX jited:1 311 PASS Signed-off-by: Nicolas Schichan <nschichan@freebox.fr> Acked-by: Alexei Starovoitov <ast@kernel.org> Signed-off-by: David S.
