These are patches addressing -Wmissing-prototypes warnings in common
kernel code and memory management code files that usually get merged
through the -mm tree.

Andrew, can you pick these up in the -mm tree?

Arnd Bergmann (14):
  mm: percpu: unhide pcpu_embed_first_chunk prototype
  mm: page_poison: always declare __kernel_map_pages() function
  mm: sparse: mark populate_section_memmap() static
  audit: avoid missing-prototype warnings
  lib: devmem_is_allowed: include linux/io.h
  locking: add lockevent_read() prototype
  panic: hide unused global functions
  panic: make function declarations visible
  kunit: include debugfs header file
  suspend: add a arch_resume_nosmt() prototype
  init: consolidate prototypes in linux/init.h
  init: move cifs_root_data() prototype into linux/mount.h
  thread_info: move function declarations to linux/thread_info.h
  time_namespace: always provide arch_get_vdso_data() prototype for vdso

Nice catch, thanks. I'm fine with this going in via -mm, but if you'd
prefer it to go via kselftest/kunit, let me know.
