I spoke too early. Now I get a similar failure in the powerpc:allmodconfig build
(which previously failed for a different reason).

lib/built-in.o:(.discard+0x1): multiple definition of `__pcpu_unique_iommu_pool_hash'
arch/powerpc/kernel/built-in.o:(.discard+0x18): first defined here

And, yes, there are still two instances of iommu_pool_hash.

arch/powerpc/kernel/iommu.c:static DEFINE_PER_CPU(unsigned int, iommu_pool_hash);
lib/iommu-common.c:static       DEFINE_PER_CPU(unsigned int, iommu_pool_hash);
