Wei Yang	d0f8a8973f	mm/memblock: introduce a new helper memblock_estimated_nr_free_pages() ... During bootup, system may need the number of free pages in the whole system to do some calculation before all pages are freed to buddy system. Usually this number is get from totalram_pages(). Since we plan to move the free pages accounting in __free_pages_core(), this value may not represent total free pages at the early stage, especially when CONFIG_DEFERRED_STRUCT_PAGE_INIT is enabled. Instead of using raw memblock api, let's introduce a new helper for user to get the estimated number of free pages from memblock point of view.
