Revision e9c0a3f05477e18d2dae816cb61b62be1b7e90d3 authored by Dan Williams on 18 July 2019, 22:58:11 UTC, committed by Linus Torvalds on 19 July 2019, 00:08:07 UTC 
mm/sparsemem: convert kmalloc_section_memmap() to populate_section_memmap()
 
Allow sub-section sized ranges to be added to the memmap.

populate_section_memmap() takes an explict pfn range rather than
assuming a full section, and those parameters are plumbed all the way
through to vmmemap_populate().  There should be no sub-section usage in
current deployments.  New warnings are added to clarify which memmap
allocation paths are sub-section capable.
