Don't enable KVM_WERROR by default for x86-64 builds as KVM's one-off -Werror enabling is *mostly* superseded by the kernel-wide WERROR, and enabling KVM_WERROR by default can cause problems for developers working on other subsystems. E.g. subsystems that have a "zero W=1 regressions" rule can inadvertently build KVM with -Werror and W=1, and end up with build failures that are completely uninteresting to the developer (W=1 is prone to false positives, especially on older compilers). Keep KVM_WERROR as there are combinations where enabling WERROR isn't feasible, e.g. the default FRAME_WARN=1024 on i386 builds generates a non-zero number of warnings and thus errors, and there are far too many warnings throughout the kernel to enable WERROR with W=1 (building KVM with -Werror is desirable (with a sane compiler) as W=1 does generate useful warnings). Opportunistically drop the dependency on !COMPILE_TEST as it's completely meaningless (it was copied from i195's -Werror Kconfig), as the kernel's WERROR is explicitly *enabled* for COMPILE_TEST=y kernel's, i.e. enabling -Werror is obviosly not dependent on COMPILE_TEST=n.

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.
