Pass the target vCPU to the hwapic_isr_update() vendor hook so that VMX
can defer the update until after nested VM-Exit if an EOI for L1's vAPIC
occurs while L2 is active.
Note, commit d39850f57d ("KVM: x86: Drop @vcpu parameter from
kvm_x86_ops.hwapic_isr_update()") removed the parameter with the
justification that doing so "allows for a decent amount of (future)
cleanup in the APIC code", but it's not at all clear what cleanup was
intended, or if it was ever realized.
No functional change intended.

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.
