Public bug reported:
The ARM Architecture Reference Manual provides the following for
FAR_EL1:
"For a Data Abort or Watchpoint exception, if address tagging is enabled
for the address accessed by the data access that caused the exception,
then this field includes the tag."
However, I have found that the tag bits in FAR_EL1 are always clear,
even if the tag bits were set in the original access.
I can reproduce the problem on both 4.1.1 and master
(6e8a73e911f066527e775e04b98f31ebd19db600).
