[PATCH v3 0/4] x86: bpf unwinder fixes

[Josh Poimboeuf]

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()
