Initialise prefaulted PTEs as 'old' for arm64 when hardware access-flag updates are supported, which drastically improves vmscan performance. * for-next/faultaround: mm: filemap: Fix microblaze build failure with 'mmu_defconfig' mm/nommu: Fix return type of filemap_map_pages() mm: Mark anonymous struct field of 'struct vm_fault' as 'const' mm: Use static initialisers for immutable fields of 'struct vm_fault' mm: Avoid modifying vmf.address in __collapse_huge_page_swapin() mm: Pass 'address' to map to do_set_pte() and drop FAULT_FLAG_PREFAULT mm: Move immutable fields of 'struct vm_fault' into anonymous struct arm64: mm: Implement arch_wants_old_prefaulted_pte() mm: Allow architectures to request 'old' entries when prefaulting mm: Cleanup faultaround and finish_fault() codepaths
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
