Rename the various functions (and a variable) that enable virtualization to prepare for upcoming changes, and to clean up artifacts of KVM's previous behavior, which required manually juggling locks around kvm_usage_count. Drop the "nolock" qualifier from per-CPU functions now that there are no "nolock" implementations of the "all" variants, i.e. now that calling a non-nolock function from a nolock function isn't confusing (unlike this sentence). Drop "all" from the outer helpers as they no longer manually iterate over all CPUs, and because it might not be obvious what "all" refers to. In lieu of the above qualifiers, append "_cpu" to the end of the functions that are per-CPU helpers for the outer APIs. Opportunistically prepend "kvm" to all functions to help make it clear that they are KVM helpers, but mostly because there's no reason not to. Lastly, use "virtualization" instead of "hardware", because while the functions do enable virtualization in hardware, there are a _lot_ of things that KVM enables in hardware. Defer renaming the arch hooks to future patches, purely to reduce the amount of churn in a single commit.

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 reStructuredText 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.
