s390/mm: Let dump_fault_info() print additional information
Let dump_fault_info() print additional information to make debugging
easier:
Print "FSI" if the access-exception-fetch/store-indication facility is
installed. If it is installed the TEID may also indicate if an exception
happened because of a fetch or a store operation.
Print "SOP", "ESOP-1", or "ESOP-2" depending on the type of the installed
Suppression-on-Protection facility. This also gives additional information
about the validity and meaning of the TEID bits.
The output is changed from something like:
Failing address:
0000000000000000 TEID:
0000000000000803
to
Failing address:
0000000000000000 TEID:
0000000000000803 ESOP-2 FSI
