To use Fastfpe, a user is supposed to enable CONFIG_FPE_FASTFPE and put downstream source files into arch/arm/fastfpe/. It is not working for O= build because $(wildcard arch/arm/fastfpe) checks if it exists in $(objtree), not in $(srctree). Add the $(srctree)/ prefix to fix it. While I was here, I slightly refactored the code. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
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.
