The arch_timer and vgic_irq kselftests assume that they can create a vgic-v3, using the library function vgic_v3_setup() which aborts with a test failure if it is not possible to do so. Since vgic-v3 can only be instantiated on systems where the host has GICv3 this leads to false positives on older systems where that is not the case. Fix this by changing vgic_v3_setup() to return an error if the vgic can't be instantiated and have the callers skip if this happens. We could also exit flagging a skip in vgic_v3_setup() but this would prevent future test cases conditionally deciding which GIC to use or generally doing more complex output.

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.
