Setup the golden VMCS config during vmx_init(), before the call to kvm_x86_vendor_init(), instead of waiting until the callback to do hardware setup. setup_vmcs_config() only touches VMX state, i.e. doesn't poke anything in kvm.ko, and has no runtime dependencies beyond hv_init_evmcs(). Setting the VMCS config early on will allow referencing VMCS and VMX capabilities at any point during setup, e.g. to check for PERF_GLOBAL_CTRL save/load support during mediated PMU initialization.

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 reStructuredText 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.
