We currently initialize the group of private IRQs during kvm_vgic_vcpu_init, and the value of the group depends on the GIC model we are emulating. However, CPUs created before creating (and initializing) the VGIC might end up with the wrong group if the VGIC is created as GICv3 later. Since we have no enforced ordering of creating the VGIC and creating VCPUs, we can end up with part the VCPUs being properly intialized and the remaining incorrectly initialized. That also means that we have no single place to do the per-cpu data structure initialization which depends on knowing the emulated GIC model (which is only the group field). This patch removes the incorrect comment from kvm_vgic_vcpu_init and initializes the group of all previously created VCPUs's private interrupts in vgic_init in addition to the existing initialization in kvm_vgic_vcpu_init.

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.
