7f33105cdd tools/mm: fix undefined reference to pthread_once
Commit 97d5f2e9ee ("tools api fs: More thread safety for global
filesystem variables") introduces pthread_once, so the libpthread
should be added at link time, or we'll meet the following compile
error when 'make -C tools/mm':

Merge tag 'slab-for-6.4' of git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab

Pull slab updates from Vlastimil Babka:
 "The main change is naturally the SLOB removal. Since its deprecation
  in 6.2 I've seen no complaints so hopefully SLUB_(TINY) works well for
  everyone and we can proceed.

  Besides the code cleanup, the main immediate benefit will be allowing
  kfree() family of function to work on kmem_cache_alloc() objects,
  which was incompatible with SLOB. This includes kfree_rcu() which had
  no kmem_cache_free_rcu() counterpart yet and now it shouldn't be
  necessary anymore.

  Besides that, there are several small code and comment improvements
  from Thomas, Thorsten and Vernon"

9235756885 tools/mm/page_owner_sort.c: fix TGID output when cull=tg is used
When using cull option with 'tg' flag, the fprintf is using pid instead
of tgid. It should use tgid instead.

c4ba69f00c mm, page_flags: remove PG_slob_free
With SLOB removed we no longer need the PG_slob_free alias for
PG_private. Also update tools/mm/page-types.

e6d2c436ff tools/mm: allow users to provide additional cflags/ldflags
Right now there is no way to provide additional cflags/ldflags when
building tools/vm binaries.  And using eg.  make CFLAGS=<options> will
override the CFLAGS being set in the Makefile, making the build fail since
it requires the include of the ../lib dir (for libapi).

This change then allows you to specify:
CFLAGS=<options> LDFLAGS=<options> make V=1 -C tools/vm

And the options will be correctly appended as can be seen from the
make output.

799fb82aa1 tools/vm: rename tools/vm to tools/mm
Rename tools/vm to tools/mm for being more consistent with the code and
documentation directories, and won't be confused with virtual machines.
