- Avoid toggling the x2apic msr interception if it is already up to date. - Avoid touching L0 msr bitmap when AVIC is inhibited on entry to the guest mode, because in this case the guest usually uses its own msr bitmap. Later on VM exit, the 1st optimization will allow KVM to skip touching the L0 msr bitmap as well.

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.
