PMD_ORDER denotes order of magnitude for a PMD entry, i.e PMD entry size is 2 ^ PMD_ORDER. Rename PMD_ORDER to PMD_ENTRY_ORDER to allow a generic definition of PMD_ORDER as order of a PMD allocation: (PMD_SHIFT - PAGE_SHIFT).

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@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. 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.

Now all the platforms enable ARCH_HAS_GET_PAGE_PROT. They define and export own vm_get_page_prot() whether custom or standard DECLARE_VM_GET_PAGE_PROT. Hence there is no need for default generic fallback for vm_get_page_prot(). Just drop this fallback and also ARCH_HAS_GET_PAGE_PROT mechanism.

This moves protection_map[] inside the platform and while here, also enable ARCH_HAS_VM_GET_PAGE_PROT on 32 bit and nohash 64 (aka book3e/64) platforms via DECLARE_VM_GET_PAGE_PROT. Link: https://lkml.kernel.org/r/20220711070600.2378316-4-anshuman.khandual@arm.comSigned-off-by:

This just converts the generic vm_get_page_prot() implementation into a new macro i.e DECLARE_VM_GET_PAGE_PROT which later can be used across platforms when enabling them with ARCH_HAS_VM_GET_PAGE_PROT. This does not create any functional change. Link: https://lkml.kernel.org/r/20220711070600.2378316-3-anshuman.khandual@arm.comSigned-off-by:
