Sparse errors in 4.18-rc in slab.h

I am getting many of these sparse warnings in 4.18-rc1

./include/linux/slab.h:631:13: error: undefined identifier
'__builtin_mul_overflow'

They are a little distracting (I missed a more important sparse
warning due to large number of those from slab.h). Any ideas how to
silence it?
