Subject: [PATCH bpf 0/6] bpf: enhancements for multi-function programs

This patch series introduces the following:

[1] Support for bpf-to-bpf function calls in the powerpc64 JIT compiler.

[2] Provide a way for resolving function calls because of the way JITed
    images are allocated in powerpc64.

[3] Fix to get JITed instruction dumps for multi-function programs from
    the bpf system call.

Sandipan Das (6):
  bpf: support 64-bit offsets for bpf function calls
  bpf: powerpc64: add JIT support for multi-function programs
  bpf: get kernel symbol addresses via syscall
  tools: bpf: sync bpf uapi header
  tools: bpftool: resolve calls without using imm field
  bpf: fix JITed dump for multi-function programs via syscall
