The PSCI spec states that a CPU_ON call should cause the new CPU to be started in the highest implemented Non-secure exception level. We were incorrectly starting it at the exception level of the caller, which happens to be correct if EL2 is not implemented. Implement the correct logic as described in the PSCI 1.0 spec section 6.4: * if EL2 exists and SCR_EL3.HCE is set: start in EL2 * otherwise start in EL1 Backports commit 3f591a20221511c639cc7959755e570801a21cd2 from qemu |
