MIPS&LoongArch&NIOS2: adjust prototypes of p?d_init()
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.
