Sean Christopherson 791a089861 KVM: SVM: Invoke trace_kvm_exit() for fastpath VM-Exits
Move SVM's call to trace_kvm_exit() from the "slow" VM-Exit handler to
svm_vcpu_run() so that KVM traces fastpath VM-Exits that re-enter the
guest without bouncing through the slow path.  This bug is benign in the
current code base as KVM doesn't currently support any such exits on SVM.

Fixes: a9ab13ff6e ("KVM: X86: Improve latency for single target IPI fastpath")

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.
