Borislav Petkov (AMD) 0b8f64204e KVM: SVM: Set synthesized TSA CPUID flags
Commit f3f9deccfc in the LTS tree.

VERW_CLEAR is supposed to be set only by the hypervisor to denote TSA
mitigation support to a guest. SQ_NO and L1_NO are both synthesizable,
and are going to be set by hw CPUID on future machines.

So keep the kvm_cpu_cap_init_kvm_defined() invocation *and* set them
when synthesized.

This fix is stable-only.

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.
