Remove the redundant .hwapic_irr_update() ops. If a vCPU has APICv enabled, KVM updates its RVI before VM-enter to L1 in vmx_sync_pir_to_irr(). This guarantees RVI is up-to-date and aligned with the vIRR in the virtual APIC. So, no need to update RVI every time the vIRR changes. Note that KVM never updates vmcs02 RVI in .hwapic_irr_update() or vmx_sync_pir_to_irr(). So, removing .hwapic_irr_update() has no impact to the nested case.

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.
