Add a PTP clock driver called ptp_vmw, for guests running on VMware ESXi hypervisor. The driver attaches to a VMware virtual device called "precision clock" that provides a mechanism for querying host system time. Similar to existing virtual PTP clock drivers (e.g. ptp_kvm), ptp_vmw utilizes the kernel's PTP hardware clock API to implement a clock device that can be used as a reference in Chrony for synchronizing guest time with host. The driver is only applicable to x86 guests running in VMware virtual machines with precision clock virtual device present. It uses a VMware specific hypercall mechanism to read time from the device.

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.
