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
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.
