Patch #1 & #2 are simple cleanup patches. Patch #3 refactors JIT compiler code with the aim to simplify adding BPF_PROBE_MEM support. Patch #4 introduces PPC_RAW_BRANCH() macro instead of open coding branch instruction. Patch #5 & #7 add BPF_PROBE_MEM support for PPC64 & PPC32 JIT compilers respectively. Patch #6 & #8 handle bad userspace pointers for PPC64 & PPC32 cases respectively.
