Patch series "mm/sparse-vmemmap: Generalise helpers and enable for LoongArch", v14. This series is in order to enable sparse-vmemmap for LoongArch. 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. This patch (of 4): We are preparing to add sparse vmemmap support to LoongArch. MIPS and LoongArch need to call pgd_init()/pud_init()/pmd_init() when populating page tables, so adjust their prototypes to make generic helpers can call them. NIOS2 declares pmd_init() but doesn't use, just remove it to avoid build errors.
