Liran Alon f497b6c25d KVM: nVMX: Optimization: Dont set KVM_REQ_EVENT when VMExit with nested_run_pending
When vCPU runs L2 and there is a pending event that requires to exit
from L2 to L1 and nested_run_pending=1, vcpu_enter_guest() will request
an immediate-exit from L2 (See req_immediate_exit).

Since now handling of req_immediate_exit also makes sure to set
KVM_REQ_EVENT, there is no need to also set it on vmx_vcpu_run() when
nested_run_pending=1.

This optimizes cases where VMRESUME was executed by L1 to enter L2 and
there is no pending events that require exit from L2 to L1. Previously,
this would have set KVM_REQ_EVENT unnecessarly.

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
