[PATCH bpf-next v3 00/10] bpf: enhancements for multi-function programs

[Sandipan Das]

v3:
 - Change base tree tag to bpf-next.
 - Incorporate review comments from Alexei, Daniel and Jakub.
 - Make sure that the JITed image does not grow or shrink after
   the last pass due to the way the instruction sequence used
   to load a callee's address maybe optimized.
 - Make additional changes to the bpf system call and bpftool to
   make multi-function JITed dumps easier to correlate.

v2:
 - Incorporate review comments from Jakub.

Sandipan Das (10):
  bpf: support 64-bit offsets for bpf function calls
  bpf: powerpc64: pad function address loads with NOPs
  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 multi-function JITed dump obtained via syscall
  bpf: get JITed image lengths of functions via syscall
  tools: bpf: sync bpf uapi header
  tools: bpftool: add delimiters to multi-function JITed dumps
