Thanks Will! I've added your acked-by to the entire series, also tweaked 14/14's commit log to indicate that it's been tested on Juno as well. >> >> It's a bit late for 3.17 now, so I guess we'll queue this for 3.18 (which >> also means the dependency on -next isn't an issue).

Hmm... if net-next is still open, and David is willing to pull in this series, I share Alexei's opinion -- don't see why a delay is necessary. David, any chance of pulling this series into net-next for 3.17? BTW, I also tried merging 'git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux.git for-next/core' with this series. The example merge is available at 'https://github.com/zlim/linux.git arm64/bpf-merge'. The merge conflict resolution is really trivial: --------8<-------- diff --cc arch/arm64/Kconfig index 7534a80a,ce6e733..c165c91 --- a/arch/arm64/Kconfig +++ b/arch/arm64/Kconfig @@@ -32,8 -33,8 +34,9 @@@ config ARM6 select HAVE_ARCH_JUMP_LABEL select HAVE_ARCH_KGDB select HAVE_ARCH_TRACEHOOK - select HAVE_C_RECORDMCOUNT + select HAVE_BPF_JIT + select HAVE_C_RECORDMCOUNT + select HAVE_CC_STACKPROTECTOR select HAVE_DEBUG_BUGVERBOSE select HAVE_DEBUG_KMEMLEAK select HAVE_DMA_API_DEBUG -------->8-------- Anyway, here's an updated branch (with Will's acks, commit log tweak noting Will's testing on real hardware, rebase on net-next). I can repost entire patch series if needed. ---------------------------------------------------------------- The following changes since commit 52c4f0ec662bbf02f1b0bcb311a48af2c8e5ee89: drivers: net: cpsw: add support to dump ALE table via ethtool register dump (2014-07-22 19:58:25 -0700) are available in the git repository at: https://github.com/zlim/linux.git arm64/bpf for you to fetch changes up to 533f668ff3e8d69f22c6e5432e0eb1005f2e8970: arm64: eBPF JIT compiler (2014-07-22 21:52:09 -0700) ---------------------------------------------------------------- -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
