Revision 6c922cf75115c8b389c091a073209ca45f1af530 authored by Miaohe Lin on 26 February 2021, 01:17:21 UTC, committed by Linus Torvalds on 26 February 2021, 17:41:00 UTC
Commit 108bcc96ef70 ("mm: add & use zone_end_pfn() and zone_spans_pfn()") introduced the helper zone_end_pfn() to calculate the zone end pfn. But update_pgdat_span() forgot to use it. Use this helper and rename local variable zone_end_pfn to end_pfn to avoid a naming conflict with the existing zone_end_pfn().
