+scheduler.stp: Handle missing symbols.
+
+Compiler output code optimization leads to missing debug data for some
+target variables, in particular some inline functions parameters, e.g.
+context_switch.
+
+Handle this by testing for variable name resolvability and provide default
+variable values in case no suitable target data is available through variable
+name. Affected functions: ctxswitch,wakeup.
+
+This fix does not affect the intended context switch tracing.

+compat_sendfile syscall is unavailable in kernels starting version 3.8.
