[PATCH 1/2] tracing: Fix function-graph build warning on 32-bit

[Frederic Weisbecker]

From: Borislav Petkov <bp@xxxxxxxxx>

Fix

kernel/trace/trace_functions_graph.c: In function âtrace_print_graph_durationâ:
kernel/trace/trace_functions_graph.c:652: warning: comparison of distinct pointer types lacks a cast

when building 36-rc6 on a 32-bit due to the strict type check failing
in the min() macro.
