Hi,
The question what does PxD_ORDER define raises from time to time and there is still a conflict between MIPS and DAX definitions.
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.
Matthew Wilcox (Oracle) (1): mips: Rename PMD_ORDER to PMD_TABLE_ORDER
Mike Rapoport (13): csky: drop definition of PTE_ORDER csky: drop definition of PGD_ORDER mips: Rename PUD_ORDER to PUD_TABLE_ORDER mips: drop definitions of PTE_ORDER mips: Rename PGD_ORDER to PGD_TABLE_ORDER nios2: drop definition of PTE_ORDER nios2: drop definition of PGD_ORDER loongarch: drop definition of PTE_ORDER loongarch: drop definition of PMD_ORDER loongarch: drop definition of PUD_ORDER loongarch: drop definition of PGD_ORDER parisc: Rename PGD_ORDER to PGD_TABLE_ORDER xtensa: drop definition of PGD_ORDER
