CMA imposes system-wide memory constraints by reserving boot-time memory and restricting it to movable allocations. This alters allocator behavior even when CMA is not explicitly used. Since CMA sizing and applicability are platform-specific, mm/Kconfig intentionally provides no default opt-in for CONFIG_CMA.
