Changes from v1:
	Now SLAB passes requests larger than order-1 page
	to page allocator.

	Adjusted comments from Matthew, Vlastimil, Rientjes.
	Thank you for feedback!

	BTW, I have no idea what __ksize() should return when an object that
	is not allocated from slab is passed. both 0 and folio_size()
	seems wrong to me.

Hello, these are cleanup patches for slab.
Please consider them for slab-next :)

Any comments will be appreciated.
Thanks.

  mm/slab: kmalloc: pass requests larger than order-1 page to page
    allocator
  mm/sl[au]b: unify __ksize()
  mm/sl[auo]b: move definition of __ksize() to mm/slab.h
  mm/slub: limit number of node partial slabs only in cache creation
  mm/slub: refactor deactivate_slab()

Didn't we say 0 would be the safer of the two options?
