Who: Laurent Pinchart <laurent.pinchart@ideasonboard.com>

----------------------------
+
+What: CONFIG_UNSAFE_VSYSCALLS (x86_64)
+When: When glibc 2.14 or newer is ubitquitous. Perhaps mid-2012.
+Why: Having user-executable code at a fixed address is a security problem.
+ Turning off CONFIG_UNSAFE_VSYSCALLS mostly removes the risk but will
+ make the time() function slower on glibc versions 2.13 and below.
