It is on top of mm-everything-2022-08-11-02-10. Motivation =3D=3D=3D This enables kernel to allocate 1GB pages and is necessary for my ongoing w= ork on adding support for 1GB PUD THP[1]. This is also the conclusion I came up= with after some discussion with David Hildenbrand on what methods should be used= for allocating gigantic pages[2], since other approaches like using CMA allocat= or or alloc_contig_pages() are regarded as suboptimal. In addition, make MAX_ORDER a kernel boot time parameter can enable user to adjust buddy allocator without recompiling the kernel for their own needs, = so that one can still have a small MAX_ORDER if he/she does not need to alloca= te gigantic pages like 1GB PUD THPs. Background =3D=3D=3D At the moment, kernel imposes MAX_ORDER - 1 + PAGE_SHFIT < SECTION_SIZE_BITS restriction. This prevents buddy allocator merging pages across memory sect= ions, as PFNs might not be contiguous and code like page++ would fail. But this w= ould not be an issue when SPARSEMEM_VMEMMAP is set, since all struct page are virtually contiguous. So boot time adjustable MAX_ORDER depends on SPARSEMEM_VMEMMAP. Description =3D=3D=3D I tested the patchset on both x86_64 and ARM64 at 4KB base pages. The syste= ms boot and run. It definitely needs more tests and reviews. In terms of the concerns on performance degradation if MAX_ORDER is increas= ed, I run vm-scalability from lkp comparing current system, my patchset with MAX_ORDER=3D11 and my patchset with MAX_ORDER=3D20 on a x86_64 VM and saw almost no performance difference, please attached vm-scalability reports. Patch 1 renames FORCE_MAX_ZONEORDER to ARCH_FORCE_MAX_ORDER for a more precise description. Patch 2 changes MAX_ORDER to represent the max order of pages allocated by buddy allocator. right now MAX_ORDER - 1 represents that and it is confusing. Suggested by Vlastimil Babka. Patch 3 replaces MAX_ORDER with MAX_PHYS_CONTIG_ORDER when it is used to indicate the maximum number of physically contiguous pages. Patch 4 fixes deferred struct page initialization when MAX_ORDER is bigger than a memory section size. Patch 5-8 convert the use of MAX_ORDER to pageblock_order. Since pageblock_order is a constant when MAX_ORDER can be changed at boot time and close to current MAX_ORDER value. I separate changes to different patch= es for easy review and can merge them into a single one if that works better. Patch 9 adds a new Kconfig option SET_MAX_ORDER to allow specifying MAX_ORD= ER when ARCH_FORCE_MAX_ORDER is not used by the arch, like x86_64. Patch 10 converts statically allocated arrays with MAX_ORDER length to dyna= mic ones if possible and prepares for making MAX_ORDER a boot time parameter. Patch 11 adds a new MIN_MAX_ORDER constant to replace soon-to-be-dynamic MAX_ORDER for places where converting static array to dynamic one is causing hassle and not necessary, i.e., ARM64 hypervisor page allocation and SLAB. Patch 12 changes MAX_ORDER to be a kernel boot time parameter and it is opt-in as an mm/Kconfig option. Any suggestion and/or comment is welcome. Thanks.
