Back in 2010 you made CONFIG_SWIOTLB mandatory (commit b93b2a). This prevents

this option to be disabled if CONFIG_EXPERT is set?

Ralf has the final say, so it really is not up to me.

That said, any patch that improves the flexibility of the kernel without adversely effecting reliability and correctness would be welcome.

I suspect some users of Octeon can
review their hardware to be sure it's save to do.
