[PATCH 0/3] small: Prepare ground for madvise

[Cyrill Gorcunov]

We need to eliminate some slab areas from coredump, for
this sake lets provide a way to small allocator to advise
memory system about our wish.

Guys, this is early RFC, comments and ideas on API are welcome.

Cyrill Gorcunov (3):
  build: Check for madvise syscall
  slab_arena: Provide slab_arena_madvise_create to madvice slabs
  test: slab_arena -- Verify madvise
