mm/kmemcheck.c also needs slab.h added to it:

Fix build errors due to missing slab.h:

mm/kmemcheck.c:69: error: dereferencing pointer to incomplete type
mm/kmemcheck.c:69: error: 'SLAB_NOTRACK' undeclared (first use in this function)
mm/kmemcheck.c:82: error: dereferencing pointer to incomplete type
mm/kmemcheck.c:94: error: dereferencing pointer to incomplete type
mm/kmemcheck.c:94: error: dereferencing pointer to incomplete type
mm/kmemcheck.c:94: error: 'SLAB_DESTROY_BY_RCU' undeclared (first use in this function)
