mainlining shenanigans
The intel8x0 driver tries to measure the AC97 bus clock at the probe time because there have been machines that are driven in different rate (44.1kHz vs 48kHz). This was the past and currently most of usages of this driver are on VM, and those are certainly fixed with 48k clock, hence it's useless and waste of time to measure. This patch is an optimization, setting the fixed 48k rate if it's detected to be running on a VM.

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.
