calculate_bandwidth() is presently broken on all !(X86_64 || SPARC64 || ARM64)
architectures built with Clang (all released versions), whereby the stack
frame gets blown up to well over 5k. This would cause an immediate kernel
panic on most architectures. We'll revert this when the following bug report
has been resolved: https://github.com/llvm/llvm-project/issues/41896.
