Peter Gonda f43c887cb7 KVM: SEV: Update svm_vm_copy_asid_from for SEV-ES 
For mirroring SEV-ES the mirror VM will need more then just the ASID.
The FD and the handle are required to all the mirror to call psp
commands. The mirror VM will need to call KVM_SEV_LAUNCH_UPDATE_VMSA to
setup its vCPUs' VMSAs for SEV-ES.

README 

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.
