Restructure the code and add the unwind annotations so that both the frame pointer unwinder as well as the EHABI unwind info based unwinder will be able to follow the call stack through call_with_stack(). Since GCC and Clang use different formats for the stack frame, two methods are implemented: a GCC version that pushes fp, sp, lr and pc for compatibility with the frame pointer unwinder, and a second version that works with Clang, as well as with the EHABI unwinder both in ARM and Thumb2 modes.

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.
