V1: The initial patch used the approach to abort at the first instance of PMD_SIZE allocation failure, unmaps all previously mapped sections using vmemmap_free and maps the entire request with vmemmap_populate_basepages to allocate virtually contiguous memory. https://lkml.org/lkml/2020/9/10/66
V2: Allocates virtually contiguous memory only for sections that failed PMD_SIZE allocation, and continues to allocate physically contiguous memory for other sections. https://lkml.org/lkml/2020/9/30/1489
V3: Addresses Anshuman's comment to allow fallback to altmap base pages as well if and when required.
