Kai Huang 6e44d2427b KVM: x86: Fix a comment inside __kvm_set_or_clear_apicv_inhibit() 
Change svm_vcpu_run() to vcpu_enter_guest() in the comment of
__kvm_set_or_clear_apicv_inhibit() to make it reflect the fact.

When one thread updates VM's APICv state due to updating the APICv
inhibit reasons, it kicks off all vCPUs and makes them wait until the
new reason has been updated and can be seen by all vCPUs.

There was one WARN() to make sure VM's APICv state is consistent with
vCPU's APICv state in the svm_vcpu_run().  Commit ee49a89329 ("KVM:
x86: Move SVM's APICv sanity check to common x86") moved that WARN() to
x86 common code vcpu_enter_guest() due to the logic is not unique to
SVM, and added comments to both __kvm_set_or_clear_apicv_inhibit() and
vcpu_enter_guest() to explain this.

However, although the comment in __kvm_set_or_clear_apicv_inhibit()
mentioned the WARN(), it seems forgot to reflect that the WARN() had
been moved to x86 common, i.e., it still mentioned the svm_vcpu_run()
but not vcpu_enter_guest().  Fix it.

Note after the change the first line that contains vcpu_enter_guest()
exceeds 80 characters, but leave it as is to make the diff clean.

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 reStructuredText 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.
