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 continous to allocate physically contiguous memory for other sections. https://lkml.org/lkml/2020/9/30/1489 V3: Addressed trivial review comments. Pass in altmap to vmemmap_populate_basepages.
