Merge branch kvm-arm64/misc-7.2 into kvmarm-master/next

* kvm-arm64/misc-7.2:
  : .
  : - Check for a valid vcpu pointer upon deactivating traps when handling
  :   a HYP panic in VHE mode
  :
  : - Make the __deactivate_fgt() macro use its arguments instead of the
  :   surrounding context
  :
  : - Don't bother with initialising TPIDR_EL2 in the hyp stubs, as this
  :   is already taken care of in more obvious places
  :
  : - Drop the unused kvm_arch pointer passed to __load_stage2()
  :
  : - Return -EOPNOTSUPP when a hypercall fails for some reason, instead of
  :   returning whatever was in the result structure
  :
  : - Make the ITS ABI selection helpers return void, which avoids wondering
  :   about the nature of the return code (always 0)
  : .
