Subject: [PATCH] mm.h: include slab.h for kmalloc/kfree

The upstream header cleanup that took place between the rev
list ^9e74e7c b66696e breaks RT pte_lock changes with:

  include/linux/mm.h: In function 'pte_lock_init':
  include/linux/mm.h:1115: error: implicit declaration of function 'kmalloc'
  include/linux/mm.h: In function 'pte_lock_deinit':
  include/linux/mm.h:1127: error: implicit declaration of function 'kfree'

The assoc. tip change which introduces this dependency is 27909c8793,
	"mm: shrink the page frame to !-rt size"
