mainlining shenanigans
4c16fa3ee9
On x86-64, set KVM's supported CPUID as the vCPU's CPUID when recreating a VM+vCPU to deduplicate code for state save/restore tests, and to provide symmetry of sorts with respect to vm_create_with_one_vcpu(). The extra KVM_SET_CPUID2 call is wasteful for Hyper-V, but ultimately is nothing more than an expensive nop, and overriding the vCPU's CPUID with the Hyper-V CPUID information is the only known scenario where a state save/restore test wouldn't need/want the default CPUID. Opportunistically use __weak for the default vm_compute_max_gfn(), it's provided by tools' compiler.h.

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.
