[PATCH kallsyms, bpf 0/3] kallsym_tree for dynamic ksymbols

[Song Liu]

This set includes Peter's work to merge multiple trees for different types
of dynamic kallsyms (BPF, ftrace, etc.). Symbols for BPF programs are
migrated to use kallsym_tree.

I have made minor changes to Peter's patches, and tested them with BPF
programs and perf utility.

Thanks,
Song

  rbtree_latch: Introduce latch_tree_first() and latch_tree_next()
  kallsyms: Introduce kallsym_tree for dynamic symbols
  bpf: migrate symbols for BPF programs to kallsym_tree
