Machines big enough that such big hashes make sense are probably NUMA. And on NUMA systems you imho should rather use node interleaving vmalloc(), not a bit physical allocation on a specific node for these hashes. This will avoid memory controller hot spots and avoid the problem completely. Likely it will perform better too.
