__remove_pages() is only necessary for CONFIG_MEMORY_HOTREMOVE. PowerPC pseries will return -EOPNOTSUPP if unsupported. Adding an #ifdef causes several other functions it depends on to also become unnecessary, which saves in .text when disabled (it's disabled in most defconfigs besides powerpc, including x86). remove_memory_block() becomes static since it is not referenced outside of drivers/base/memory.c. Build tested on x86 and powerpc with CONFIG_MEMORY_HOTREMOVE both enabled and disabled.

When booting on a large memory system, the kernel spends considerable time in memmap_init_zone() setting up memory zones. Analysis shows significant time spent in __early_pfn_to_nid(). The routine memmap_init_zone() checks each PFN to verify the nid is valid. __early_pfn_to_nid() sequentially scans the list of pfn ranges to find the right range and returns the nid. This does not scale well. On a 4 TB (single rack) system there are 308 memory ranges to scan. The higher the PFN the more time spent sequentially spinning through memory ranges. Since memmap_init_zone() increments pfn, it will almost always be looking for the same range as the previous pfn, so check that range first. If it is in the same range, return that nid. If not, scan the list as before. A 4 TB (single rack) UV1 system takes 512 seconds to get through the zone code. This performance optimization reduces the time by 189 seconds, a 36% improvement. A 2 TB (single rack) UV2 system goes from 212.7 seconds to 99.8 seconds, a 112.9 second (53%) reduction.

Memory hotplug can happen on a machine under load, memory shortness and fragmentation, so huge page allocations for the vmemmap are not guaranteed to succeed.

The sparse code, when asking the architecture to populate the vmemmap, specifies the section range as a starting page and a number of pages. This is an awkward interface, because none of the arch-specific code actually thinks of the range in terms of 'struct page' units and always translates it to bytes first. In addition, later patches mix huge page and regular page backing for the vmemmap. For this, they need to call vmemmap_populate_basepages() on sub-section ranges with PAGE_SIZE and PMD_SIZE in mind. But these are not necessarily multiples of the 'struct page' size and so this unit is too coarse. Just translate the section range into bytes once in the generic sparse code, then pass byte ranges down the stack.

ARM processors with LPAE enabled use 3 levels of page tables, with an entry in the top level (pgd) covering 1GB of virtual space. Because of the branch relocation limitations on ARM, the loadable modules are mapped 16MB below PAGE_OFFSET, making the corresponding 1GB pgd shared between kernel modules and user space. If free_pgtables() is called with the default ceiling 0, free_pgd_range() (and subsequently called functions) also frees the page table shared between user space and kernel modules (which is normally handled by the ARM-specific pgd_free() function). This patch changes defines the ARM USER_PGTABLES_CEILING to TASK_SIZE when CONFIG_ARM_LPAE is enabled. Note that the pgd_free() function already checks the presence of the shared pmd page allocated by pgd_alloc() and frees it, though with ceiling 0 this wasn't necessary.

This patchset removes vm_struct list management after initializing vmalloc. Adding and removing an entry to vmlist is linear time complexity, so it is inefficient. If we maintain this list, overall time complexity of adding and removing area to vmalloc space is O(N), although we use rbtree for finding vacant place and it's time complexity is just O(logN). And vmlist and vmlist_lock is used many places of outside of vmalloc.c. It is preferable that we hide this raw data structure and provide well-defined function for supporting them, because it makes that they cannot mistake when manipulating theses structure and it makes us easily maintain vmalloc layer. For kexec and makedumpfile, I export vmap_area_list, instead of vmlist. This comes from Atsushi's recommendation. For more information, please refer below link. https://lkml.org/lkml/2012/12/6/184 This patch: The purpose of iterating a vmlist is finding vm area with specific virtual address. find_vm_area() is provided for this purpose and more efficient, because it uses a rbtree. So change it.

Commit abf09bed ("s390/mm: implement software dirty bits") introduced another difference in the pte layout vs. the pmd layout on s390, thoroughly breaking the s390 support for hugetlbfs. This requires replacing some more pte_xxx functions in mm/hugetlbfs.c with a huge_pte_xxx version. This patch introduces those huge_pte_xxx functions and their generic implementation in asm-generic/hugetlb.h, which will now be included on all architectures supporting hugetlbfs apart from s390. This change will be a no-op for those architectures.
