GCC uses the number of lines of an inline assembly to calculate its length (number of instructions). This has an impact on GCCs inlining decisions. Therefore remove superfluous new lines from a couple of inline assemblies, so that their real size is reflected. Also use an "asm inline" statement for the fpu_lfpc_safe() inline assembly to enforce that GCC assumes the minimum size for this inline assembly, since it contains various statements which make it appear much larger than the resulting code is.

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.
