Samuel Holland b0b8a15bb8 x86: implement ARCH_HAS_KERNEL_FPU_SUPPORT
x86 already provides kernel_fpu_begin() and kernel_fpu_end(), but in a
different header.  Add a wrapper header, and export the CFLAGS adjustments
as found in lib/Makefile.

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 reStructuredText 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.
