commita58a66afc4upstream. Don't inhibit APICv/AVIC due to an xAPIC ID mismatch if the APIC is hardware disabled. The ID cannot be consumed while the APIC is disabled, and the ID is guaranteed to be set back to the vcpu_id when the APIC is hardware enabled (architectural behavior correctly emulated by KVM).

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.
