Matt Redfearn 735302665c MIPS: PCI: Fix smp_processor_id() in preemptible ... Commit 1c3c5eab17 ("sched/core: Enable might_sleep() and smp_processor_id() checks early") enables checks for might_sleep() and smp_processor_id() being used in preemptible code earlier in the boot than before. This results in a new BUG from pcibios_set_cache_line_size().

These macros are the "proper" way to determine the CPU cache sizes. This makes use of the newly added cpu_tcache_line_size.
