WARN and don't restart the hrtimer if KVM's callback runs with the guest's APIC timer in periodic mode but with a period of '0', as not advancing the hrtimer's deadline would put the CPU into an infinite loop of hrtimer events. Observing a period of '0' should be impossible, even when the hrtimer is running on a different CPU than the vCPU, as KVM is supposed to cancel the hrtimer before changing (or zeroing) the period, e.g. when switching from periodic to one-shot.

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.
