Boyan Karatotev 1d6d6802dd fix(pmu): unconditionally save PMCR_EL0 Reading back a RES0 bit does not necessarily mean it will be read as 0. The Arm ARM explicitly warns against doing this. The PMU initialisation code tries to set such bits to 1 (in MDCR_EL3) regardless of whether they are in use or are RES0, checking their value could be wrong and PMCR_EL0 might not end up being saved. Save PMCR_EL0 unconditionally to prevent this. Remove the security state change as the outgoing state is not relevant to what the root world context should look like.
