In an excess of caution, commit 6f63e81bda ("KVM: PPC: Book3S: Add
MMIO emulation for FP and VSX instructions", 2017-02-21) included
checks for the case that vcpu->arch.mmio_vsx_copy_nums is less than
zero, even though its type is u8. This causes a Coverity warning,
so we remove the check for < 0. We also adjust the associated
comment to be more accurate ("4 or less" rather than "less than 4").

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.
