Architectures like powerpc will like to use different page table allocators and mapping mechanisms to implement vmemmap optimization. Similar to vmemmap_populate allow architectures to implement vmemap_populate_compound_pages Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@xxxxxxxxxxxxx> --- mm/sparse-vmemmap.c | 3 +++ 1 file changed, 3 insertions(+) diff --git a/mm/sparse-vmemmap.c b/mm/sparse-vmemmap.c index a044a130405b..541b3f69a481 100644 --- a/mm/sparse-vmemmap.c +++ b/mm/sparse-vmemmap.c @@ -141,6 +141,7 @@ void __meminit vmemmap_verify(pte_t *pte, int node, start, end - 1); } +#ifndef vmemmap_populate_compound_pages pte_t * __meminit vmemmap_pte_populate(pmd_t *pmd, unsigned long addr, int node, struct vmem_altmap *altmap, struct page *reuse) @@ -446,6 +447,8 @@ static int __meminit vmemmap_populate_compound_pages(unsigned long start_pfn, return 0; } +#endif + struct page * __meminit __populate_section_memmap(unsigned long pfn, unsigned long nr_pages, int nid, struct vmem_altmap *altmap, struct dev_pagemap *pgmap) -- 2.41.0
