Now that the MMU is re-enabled before calling the transfer function, we don't need anymore that hack with the address of the handler and the return function sitting just after the 'bl' to the transfer fonction, that function is retrieving via a read relative to 'lr'. Do a regular call to the transfer function, then to the handler, then branch to the return function.

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.
