Vlastimil Babka 769682164d mm, slab: restore NUMA policy support for large kmalloc 
commit e2d18cbf17 upstream.

The slab allocator observes the task's NUMA policy in various places
such as allocating slab pages. Large kmalloc() allocations used to do
that too, until an unintended change by c4cab55752 ("mm/slab_common:
cleanup kmalloc_large()") resulted in ignoring mempolicy and just
preferring the local node. Restore the NUMA policy support.

Fixes: c4cab55752 ("mm/slab_common: cleanup kmalloc_large()")
