Currently we save host state like user-visible host MSRs, and do some initial guest register setup for MSR_TSC_AUX and MSR_AMD64_TSC_RATIO in svm_vcpu_load(). Defer this until just before we enter the guest by moving the handling to kvm_x86_ops.prepare_guest_switch() similarly to how it is done for the VMX implementation. Additionally, since handling of saving/restoring host user MSRs is the same both with/without SEV-ES enabled, move that handling to common code.

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.
