Dave Martin 005781be12 arm64: KVM: Move CPU ID reg trap setup off the world switch path ... The HCR_EL2.TID3 flag needs to be set when trapping guest access to the CPU ID registers is required. However, the decision about whether to set this bit does not need to be repeated at every switch to the guest. Instead, it's sufficient to make this decision once and record the outcome. This patch moves the decision to vcpu_reset_hcr() and records the choice made in vcpu->arch.hcr_el2. The world switch code can then load this directly when switching to the guest without the need for conditional logic on the critical path.
