Will Deacon d44679fb95 drivers/virt: pkvm: Don't fail ioremap() call if MMIO_GUARD fails ... Calling the MMIO_GUARD hypercall from guests which have not been enrolled (e.g. because they are running without pvmfw) results in -EINVAL being returned. In this case, MMIO_GUARD is not active and so we can simply proceed with the normal ioremap() routine. Don't fail ioremap() if MMIO_GUARD fails; instead WARN_ON_ONCE() to highlight that the pvm environment is slightly wonky.
