Documentation: headers_install.txt is part of kbuild
'headers_install.txt' from Documentation/make/ is related to Kbuild so it must be moved in Documentation/kbuild/ directory. As Documentation/make/ directory has only one file, it will be removed as a consequence of moving 'headers_install.txt'. Cc: Kirill A.

-Exporting kernel headers for use by userspace
-=============================================
-
-The "make headers_install" command exports the kernel's header files in a
-form suitable for use by userspace programs.
-
-The linux kernel's exported header files describe the API for user space
-programs attempting to use kernel services. These kernel header files are
-used by the system's C library (such as glibc or uClibc) to define available
-system calls, as well as constants and structures to be used with these
-system calls. The C library's header files include the kernel header files
-from the "linux" subdirectory. The system's libc headers are usually
-installed at the default location /usr/include and the kernel headers in
-subdirectories under that (most notably /usr/include/linux and
-/usr/include/asm).
-
-Kernel headers are backwards compatible, but not forwards compatible. This
-means that a program built against a C library using older kernel headers
-should run on a newer kernel (although it may not have access to new
-features), but a program built against newer kernel headers may not work on an
-older kernel.
-
-The "make headers_install" command can be run in the top level directory of the
-kernel source code (or using a standard out-of-tree build). It takes two
-optional arguments:
-
- make headers_install ARCH=i386 INSTALL_HDR_PATH=/usr/include
-
-ARCH indicates which architecture to produce headers for, and defaults to the
-current architecture. The linux/asm directory of the exported kernel headers
-is platform-specific, to see a complete list of supported architectures use
-the command:
-
- ls -d include/asm-* | sed 's/.*-//'
-
-INSTALL_HDR_PATH indicates where to install the headers. It defaults to
-"./usr/include".
-
-The command "make headers_install_all" exports headers for all architectures
-simultaneously. (This is mostly of interest to distribution maintainers,
-who create an architecture-independent tarball from the resulting include
-directory.) You also can use HDR_ARCH_LIST to specify list of architectures.
-Remember to provide the appropriate linux/asm directory via "mv" or "ln -s"
-before building a C library with headers exported this way.
-
-The kernel header export infrastructure is maintained by David Woodhouse
