James Morse e8ec032b18 KVM: arm64: Restore host physical timer access on hyp_panic() ... When KVM panics, it hurridly restores the host context and parachutes into the host's panic() code. At some point panic() touches the physical timer/counter. Unless we are an arm64 system with VHE, this traps back to EL2. If we're lucky, we panic again. Add a __timer_save_state() call to KVMs hyp_panic() path, this saves the guest registers and disables the traps for the host.
