The new assembly code works on both 32 bit and 64 bit cpus and allows for more compiler optimisations. Since clang runs out of registers on 32 bit x86 when using CC_OUT, we need to execute "setc" ourself. Also modify the debug message so we can still see the result (eax) when the carry flag was set. Tested with 32 bit and 64 bit kernels on a Dell Inspiron 3505.

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.
