But LoongArch cannot use generic helpers directly because MIPS&LoongArch need to call pgd_init()/pud_init()/pmd_init() when populating page tables. So we adjust the prototypes of p?d_init() to make generic helpers can call them, then enable sparse-vmemmap with generic helpers, and to be further, generalise vmemmap_populate_hugepages() for ARM64, X86 and LoongArch. V1 -> V2: Split ARCH_WANT_HUGETLB_PAGE_OPTIMIZE_VMEMMAP to a separate patch. V2 -> V3: 1, Change the Signed-off-by order of author and committer; 2, Update commit message about the build error on LoongArch. Huacai Chen and Feiyang Chen(4): MIPS&LoongArch: Adjust prototypes of p?d_init(). LoongArch: Add sparse memory vmemmap support. mm/sparse-vmemmap: Generalise vmemmap_populate_hugepages(). LoongArch: Enable ARCH_WANT_HUGETLB_PAGE_OPTIMIZE_VMEMMAP.
