From d70ddd7a5d9aa335f9b4b0c3d879e1e70ee1e4e3 Mon Sep 17 00:00:00 2001 From: Mel Gorman Date: Tue, 30 Jun 2015 14:56:52 -0700 Subject: mm: page_alloc: pass PFN to __free_pages_bootmem __free_pages_bootmem prepares a page for release to the buddy allocator and assumes that the struct page is initialised. Parallel initialisation of struct pages defers initialisation and __free_pages_bootmem can be called for struct pages that cannot yet map struct page to PFN. This patch passes PFN to __free_pages_bootmem with no other functional change.
