Subject[PATCH v2] arm64/mm: add fallback option to allocate virtually
Date
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.
