# space can be handled with less contention: split it at this NR_CPUS.
# Default to 4 for wider testing, though 8 might be more appropriate.
# ARM's adjust_pte (unused if VIPT) depends on mm-wide page_table_lock.
# PA-RISC's debug spinlock_t is too large for the 32-bit struct page.
# ARM26 and SPARC32 and PPC64 may use one page for multiple page tables.
# PA-RISC 7xxx's spinlock_t would enlarge struct page from 32 to 44 bytes.
