Remove the per-vCPU "cache" of the reference pvclock and instead cache only the TSC shift+multiplier. All other fields in pvclock are fully recomputed by kvm_guest_time_update(), i.e. aren't actually persisted. In addition to shaving a few bytes, explicitly tracking the TSC shift/mul fields makes it easier to see that those fields are tied to hw_tsc_khz (they exist to avoid having to do expensive math in the common case). And conversely, not tracking the other fields makes it easier to see that things like the version number are pulled from the guest's copy, not from KVM's reference.

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.
