The existing Hyper-V wrappers for getting and setting MSRs are hv_get/set_msr(). Via hv_get/set_non_nested_msr(), they detect when running in a CoCo VM with a paravisor, and use the TDX or SNP guest-host communication protocol to bypass the paravisor and go directly to the host hypervisor for SynIC MSRs. The "set" function also implements the required special handling for the SINT MSRs. Provide functions that allow manipulating the SynIC registers through the paravisor. Move vmbus_signal_eom() to a more appropriate location (which also avoids breaking KVM).

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.
