fault-injection: allow stacktrace filter for x86-64
This patchset allow fault injection to run on x86_64 and makes stacktrace filter work as expected. With this, we can test a device driver module with fault injection more easily. This patch (of 4): FAULT_INJECTION_STACKTRACE_FILTER option was apparently disallowed on x86_64 because of problems with the stack unwinder: commit 6d690dcac92a84f98fd774862628ff871b713660 Author: Akinobu Mita <akinobu.mita@gmail.com> Date: Sat May 12 10:36:53 2007 -0700 fault injection: disable stacktrace filter for x86-64 However, there is no problems whatsoever with this today. Let's allow it again.
