This series fixes pfn_valid() for ZONE_DEVICE based memory and also improves its performance for normal hotplug memory. While here, it also reorganizes pfn_valid() on CONFIG_SPARSEMEM. This series is based on v5.11-rc5.
Question - should pfn_section_valid() be tested both for boot and non boot memory as well ?
