Marius Strobl 0dc487341e For USIII CPUs the type of the trap caused by peeking/poking non-existent
PCI devices apparently was changed from a special deferred trap with TPC
pointing to the membar #Sync following the failing load/store instruction
to a precise trap with TPC pointing to the failing load/store instruction.
Thus remove the check the check whether TPC points to a membar #Sync in
case of a data access trap as it's off-by-one for USIII CPUs and it should
be sufficient to check whether the trap happend while in fasword*() to
properly detect traps caused by peeking/poking. This also corresponds to
what other OSs do. Note that also only the USIIi manual suggests to check
the TPC for such traps while the USII one doesn't (in the public USIII
manual device peeking/poking isn't mentioned at all).
