[PATCH v7 0/5] optimize memblock_next_valid_pfn and early_pfn_valid on arm and arm64

Commit b92df1de5d28 ("mm: page_alloc: skip over regions of invalid pfns where possible") tried to optimize the loop in memmap_init_zone(). But there is still some room for improvement. Patch 1 remain the memblock_next_valid_pfn on arm and arm64 Patch 2 optimizes the memblock_next_valid_pfn()
