Stacktrace filtering for fault injection has been disabled on x86-64 since
2007 due to the lack of a DWARF unwinder. See commit 6d690dcac92a ("fault
injection: disable stacktrace filter for x86-64").
In 2017, the ORC unwider, an alternative to DWARF unwinder has been added
in commit ee9f8fce9964 ("x86/unwind: Add the ORC unwinder").
We can now re-enable the stacktrace filter for x86-64.
