The SERIALIZE instruction is supported by Tntel processors, like Sapphire Rapids. SERIALIZE is a faster serializing instruction which does not modify registers, arithmetic flags or memory, will not cause VM exit. It's availability is indicated by CPUID.(EAX=7,ECX=0):ECX[bit 14]. Expose it in KVM supported CPUID. This way, KVM could pass this information to guests and they can make use of these features accordingly.

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.
