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. V3 -> V4: Change pmd to pmdp for ARM64 for consistency. V4 -> V5: Add a detailed comment for no-fallback in the altmap case. V5 -> V6: 1, Fix build error for NIOS2; 2, Fix build error for allnoconfig; 3, Update comment for no-fallback in the altmap case. V6 -> V7: Fix build warnings of "no previous prototype". V7 -> V8: Fix build error for MIPS pud_init(). V8 -> V9: Remove redundant #include to avoid build error with latest upstream kernel. V9 -> V10: Fix build error due to VMEMMAP changes in 6.0-rc1. V10 -> V11: Adjust context due to ARM64 changes in 6.1-rc1. V11 -> V12: 1, Fix build error for !SPARSEMEM; 2, Simplify pagetable_init() for MIPS32. V12 -> V13: 1, Add Acked-by and Reviewed-by tags; 2, Update commit message for the 4th patch. V13 -> V14: Remove the static_key.h inclusion in the 4th patch. Huacai Chen and Feiyang Chen(4): MIPS&LoongArch&NIOS2: 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.
