Subject: csky: drop definition of PTE_ORDER
Date: Sun, 3 Jul 2022 17:11:50 +0300
Patch series "arch: make PxD_ORDER generically available", v2.
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@xxxxxxxxxxxxxxxxxxxx/
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.
This patch (of 15):
This is the order of the page table allocation, not the order of a PTE.
Since its always hardwired to 0, simply drop it.
