Interrupts, NMIs etc. sent while in guest mode are already handled properly by the *_interrupt_allowed callbacks, but other events can cause a vCPU to be runnable that are specific to guest mode. In the case of VMX there are two, the preemption timer and the monitor trap. The VMX preemption timer is already special cased via the hv_timer_pending callback, but the purpose of the callback can be easily extended to MTF or in fact any other event that can occur only in guest mode. Rename the callback and add an MTF check; kvm_arch_vcpu_runnable() now can return true if an MTF is pending, without relying on kvm_vcpu_running()'s call to kvm_check_nested_events(). Until that call is removed, however, the patch introduces no functional change.

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.
