This reverts commit cf3e26427c08ad9015956293ab389004ac6a338e. Multi-vCPU Hyper-V guests started crashing randomly on boot with the latest kvm/queue and the problem can be bisected the problem to this particular patch. Basically, I'm not able to boot e.g. 16-vCPU guest successfully anymore. Both Intel and AMD seem to be affected. Reverting the commit saves the day.

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.
