mm: generalize kernel PTE table allocation
[mm: generalize kernel PTE table allocation] Architectures whose empty kernel PTE representation is not all zero must initialize new kernel PTE tables. LoongArch therefore wraps __pte_alloc_one_kernel

mm: generalize PMD page table allocation
The generic PMD allocator assumes order-0 page tables and zero-valued empty entries. MIPS and LoongArch need pmd_init() to install their invalid entries, while MIPS and parisc use PMD_TABLE_ORDER to d

mm: generalize PUD page table allocation
The generic PUD allocator assumes order-0 page tables and zero-valued empty entries. MIPS and LoongArch need pud_init() to install their invalid entries. MIPS also uses PUD_TABLE_ORDER to describe the
