SLUB: Allow full duplication of kmalloc array for 390
commit 0f1f694260e0d35b5ce7d471f6e679c3dd4d7d94 upstream.
Commit 756dee75872a2a764b478e18076360b8a4ec9045 ("SLUB: Get rid of dynamic DMA
kmalloc cache allocation") makes S390 run out of kmalloc caches. Increase the
number of kmalloc caches to a safe size.
