Add it. This patch doesn't seem to have been applied along with the rest of the series. After updating to v7.2.11 on an MT8195 board I see: arch_timer: [Firmware Bug]: VHE-capable CPU without EL2 virtual timer interrupt With this patch applied, the warning is gone and the EL2 virtual timer is used as expected: arch_timer: cp15 timer running at 13.00MHz (hyp-virt).
