The patch titled
Subject: slab-use-slab_pre_alloc_hook-in-slab-allocator-shared-with-slub-fix
has been removed from the -mm tree. Its filename was
slab-use-slab_pre_alloc_hook-in-slab-allocator-shared-with-slub-fix.patch
This patch was dropped because it was folded into slab-use-slab_pre_alloc_hook-in-slab-allocator-shared-with-slub.patch

From: Jesper Dangaard Brouer <brouer@xxxxxxxxxx>
Subject: slab-use-slab_pre_alloc_hook-in-slab-allocator-shared-with-slub-fix
Second fix is for correct masking of allowed GFP flags (gfp_allowed_mask),
in SLAB allocator. This triggered a WARN, by percpu_init_late ->
pcpu_mem_zalloc invoking kzalloc with GFP_KERNEL flags. The linux-next
commit needing this fix is a1fd55538cae ("slab: use
slab_pre_alloc_hook in SLAB allocator shared with SLUB").
