Applied to bpf, thanks!

[PATCH v2 bpf 0/3] show more accurrate bpf program address

[Song Liu]

Changes v1 -> v2:
1. Added main program length to bpf_prog_info->jited_fun_lens (3/3).
2. Updated commit message of 1/3 and 2/3 with more background about the
   address masking, and why it is still save after the changes.
3. Replace "ulong" with "unsigned long".

This set improves bpf program address showed in /proc/kallsyms and in
bpf_prog_info. First, real program address is showed instead of page
address. Second, when there is no subprogram, bpf_prog_info->jited_ksyms
and bpf_prog_info->jited_fun_lens returns the main prog address and
length.

Song Liu (3):
  bpf: show real jited prog address in /proc/kallsyms
  bpf: show real jited address in bpf_prog_info->jited_ksyms
  bpf: show main program address and length in bpf_prog_info
