Commit accb757d798c ("KVM: Move vcpu_load to arch-specific
kvm_arch_vcpu_ioctl_run", 2017-12-04) added a "goto out"
statement and an "out:" label to kvm_arch_vcpu_ioctl_run().
Since the only "goto out" is inside a CONFIG_VSX block,
compiling with CONFIG_VSX=n gives a warning that label "out"
is defined but not used, and because arch/powerpc is compiled
with -Werror, that becomes a compile error that makes the kernel
build fail.
Merge commit 1ab03c072feb ("Merge tag 'kvm-ppc-next-4.16-2' of
git://git.kernel.org/pub/scm/linux/kernel/git/paulus/powerpc",
2018-02-09) added a similar block of code inside a #ifdef
CONFIG_ALTIVEC, with a "goto out" statement.
In order to make the build succeed, this adds a #ifdef around the
"out:" label. This is a minimal, ugly fix, to be replaced later
by a refactoring of the code. Since CONFIG_VSX depends on
CONFIG_ALTIVEC, it is sufficient to use #ifdef CONFIG_ALTIVEC here.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
