This series enables vmemmap backing memory allocation from device memory
ranges on arm64. But before that, it enables vmemmap_populate_basepages()
and vmemmap_alloc_block_buf() to accommodate struct vmem_altmap based
alocation requests.

This series applies on 5.8-rc4.

Changes in V4:

- Dropped 'fallback' from vmemmap_alloc_block_buf() per Catalin

Hello Andrew,

This series has been a long running one :) Now that all the three patches
here have been reviewed, could you please consider this series for merging
towards 5.9-rc1. Catalin had suggested earlier [1] that it should go via
the MM tree instead, as it touches multiple architecture. Thank you.
