Paolo Bonzini 8f042315fc KVM: nVMX: promptly process interrupts delivered while in guest mode 
commit 3a25dfa67f upstream.

Since commit c300ab9f08 ("KVM: x86: Replace late check_nested_events() hack with
more precise fix") there is no longer the certainty that check_nested_events()
tries to inject an external interrupt vmexit to L1 on every call to vcpu_enter_guest.
Therefore, even in that case we need to set KVM_REQ_EVENT.  This ensures
that inject_pending_event() is called, and from there kvm_check_nested_events().

Fixes: c300ab9f08 ("KVM: x86: Replace late check_nested_events() hack with more precise fix")

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.
