Marc Zyngier 6f00446c76 FROMGIT: KVM: arm64: Fix host's ZCR_EL2 restore on nVHE ... We re-enter the EL1 host with CPTR_EL2.TZ set in order to be able to lazily restore ZCR_EL2 when required. However, the same CPTR_EL2 configuration also leads to trapping when ZCR_EL2 is accessed from EL2. Duh! Clear CPTR_EL2.TZ *before* writing to ZCR_EL2.
