Hi David, If you plan your next revision, may be you can pick and squash following patches from my tree (https://github.com/pratyushanand/linux.git : ml_arm64_uprobe_devel_v2_over_kprobe_v4) abb0b22be54c ARM64: Move BRK opcodes defines from kprobes.h to debug-monitors.h c82c2abaf751 ARM64: kprobe: Make prepare and handler function struct kprobe independent d95c226226dc ARM64: Remove definition of ARCH64_NOP_OPCODE e5f3310a21c4 ARM64: kprobe: Fix few instruction which is to be simulated ~Pratyush -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
