v3:
- Drop even more NACKed BPF changes.
- Coincidentally, a separate fix has already been merged for JIT frame pointers:
fe8d9571dc50 ("bpf, x64: fix stack layout of JITed bpf code")
- 32-bit JIT frame pointers are still broken. I have a small patch which should fix it, if anybody wants to try interacting with the maintainer.
- Split the objtool jump table detection feature into a separate patch to clarify that it's a generic objtool feature.
Josh Poimboeuf (3): objtool: Add support for C jump tables bpf: Fix ORC unwinding in non-JIT BPF code x86/unwind/orc: Fall back to using frame pointers for generated code
Song Liu (1): perf/x86: Always store regs->ip in perf_callchain_kernel()
