This is a follow-up series with the pending patches from: https://patchwork.ozlabs.org/project/linuxppc-dev/list/?series=279602&state=* Patches 1-5 and 8 are unchanged. Patch 6 is new and patch 7 has changes based on discussion from the last series. Patch 9 has a small change to not skip the toc load for elf v2. Patches 10-17 are new to this series and are largely some cleanups to the bpf code on powerpc. - Naveen Jordan Niethe (1): powerpc64/bpf: Store temp registers' bpf to ppc mapping Naveen N.
