Now that we can dispatch all VFP and iWMMXT related undef exceptions using undef hooks implemented in C code, we no longer need the asm entry code that takes care of this unless we are using FPE, so we can move it into the FPE entry code. As this means it is ARM only, we can remove the Thumb2 specific decorations as well. It also means the non-standard, asm-only calling convention where returning via LR means failure and returning via R9 means success is now only used on legacy platforms that lack any kind of function return prediction, avoiding the associated performance impact.

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.
