The return values of fixup_exception() and arm64_bpf_fixup_exception() represent a boolean condition rather than an error code, so for clarity it would be better to return `bool` rather than `int`. This patch adjusts the code accordingly. While we're modifying the prototype, we also remove the unnecessary `extern` keyword, so that this won't look out of place when we make subsequent additions to the header. There should be no functional change as a result of this patch.

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.
