The linux-next integration testing tree

Current page initialization call flow looks like this with some
simplification:
setup_arch()
paging_init()
free_area_init()
memmap_init()
memmap_init_zone_range()
memmap_init_range()
defer_init()
__init_single_page()
mm_core_init()
mem_init()
memblock_free_all()
free_low_memory_core_early()
memmap_init_reserved_pages()
reserve_bootmem_region()
init_reserved_page()
__init_single_page()
There two cases depends on CONFIG_DEFERRED_STRUCT_PAGE_INIT.
* If CONFIG_DEFERRED_STRUCT_PAGE_INIT, pages after first_init_pfn is
skipped at defer_init(). Then init_reserved_page() is defined to
call __init_single_page() for them.
* If !CONFIG_DEFERRED_STRUCT_PAGE_INIT, pages are all initialized by
memmap_init_range().
In both cases, after init_reserved_page(), we expect __init_single_page()
has done its work to the page, which already initialize page->lru properly.
We don't need to do it again.

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 reStructuredText 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.
