ELF files built for BTI should have a program property note section which identifies them as such. The linker expects to find this note in all object files it is linking into a BTI annotated output, the compiler will ensure that this happens for C files but for assembler files we need to do this in the source so provide a macro which can be used for this purpose. To support likely future requirements for additional notes we split the defininition of the flags to set for BTI code from the macro that creates the note itself. This is mainly for use in the vDSO which should be a normal ELF shared library and should therefore include BTI annotations when built for BTI.

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.
