Subject: [PATCH v4] arm64/mm: add fallback option to allocate virtually contiguous memory

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.

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.
https://lkml.org/lkml/2020/10/12/1681

V4: Fixes checkpatch warning.
