Some time ago Matthew Wilcox suggested to use PMD_TABLE_ORDER to define the order of page table allocation: [1] https://lore.kernel.org/linux-arch/YPCJftSTUBEnq2lI@casper.infradead.org/ The parisc patch made it in, but mips didn't. Now mips defines from asm/include/pgtable.h were copied to loongarch which made it worse. Let's deal with it once and for all and rename PxD_ORDER defines to PxD_TABLE_ORDER or just drop them when the only possible order of page table is 0. I think the best way to merge this via mm tree with acks from arch maintainers.
