Hi, Here are some fixes for MIPS/BPF. The first 5 patches do some cleanup and lay the groundwork for the final one which introduces assembly helpers for MIPS and MIPS64. The goal is to speed up certain operations that do not need to go through the common C functions. This also makes the test_bpf testsuite happy with all 60 tests passing. This is based in 4.1-rc6. The patchset is also available in my git tree. https://github.com/hwoarang/linux/tree/4.3-bpf The last patch also contains performance results along with the relevant scripts and data used for the analysis.
