Introduce generic fastpath handler to handle MSR fastpath, VMX-preemption timer fastpath etc; move it after vmx_complete_interrupts() in order to catch events delivered to the guest, and abort the fast path in later patches. While at it, move the kvm_exit tracepoint so that it is printed for fastpath vmexits as well. There is no observed performance effect for the IPI fastpath after this patch.

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.
