Drop __NR_mmap2 fork in flavor of LFS, that is _FILE_OFFSET_BITS=64 (glibc & bionic) / LARGEFILE64_SOURCE (for musl) decision. It allows mmap() to use 64bit offset that is passed to mmap2 syscall. As result pgoff is not truncated and no need to use direct access to mmap2 for 32 bits systems.

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.
