The area map allocator manages the first chunk area by hiding all but the region it is responsible for serving in the area map. To align this with the populated page bitmap, end_offset is introduced to keep track of the delta to end page aligned. The area map is appended with the page aligned end when necessary to be in line with how the bitmap allocator requires the ending to be aligned with the LCM of PAGE_SIZE and the size of each bitmap block. percpu_stats is updated to ignore this region when present.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
