// std::stable_sort (used as ktl::stable_sort) uses std::get_temporary_buffer,
// which uses operator new to request a temporary buffer but then works fine
// if it can't get one.  There is no "default" memory allocation in the
// kernel, so just provide a dummy operator new that always fails so
// std::stable_sort falls back to its no-allocation algorithm.
