Nick Desaulniers ae4d682dfd compiler_attributes.h: cleanups for GCC 4.9+
Since
commit 6ec4476ac8 ("Raise gcc version requirement to 4.9")
we no longer support building the kernel with GCC 4.8; drop the
preprocess checks for __GNUC_MINOR__ version. It's implied that if
__GNUC_MAJOR__ is 4, then the only supported version of __GNUC_MINOR__
left is 9.

README

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.
