Subject: [PATCH -next v2 1/4] fault-injection: allow stacktrace filter for x86-64

From: Wei Yongjun <weiyongjun1@...wei.com>

FAULT_INJECTION_STACKTRACE_FILTER option was apparently disallowed on
x86_64 because of problems with the stack unwinder: commit 6d690dcac92a
("fault injection: disable stacktrace filter for x86-64")

However, there is no problems whatsoever with this today. Let's allow
it again.
