Subject: [PATCH 00/14] arch: make PxD_ORDER generically available
Date: Sun, 3 Jul 2022 17:11:49 +0300 [thread overview]
Message-ID: <20220703141203.147893-1-rppt@kernel.org> (raw)
From: Mike Rapoport <rppt@linux.ibm.com>
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
