From 0fd5ed8d897cffdc74903931bd7fcc9d8d154460 Mon Sep 17 00:00:00 2001 From: Rasmus Villemoes Date: Fri, 24 Jun 2016 14:50:30 -0700 Subject: init/main.c: fix initcall_blacklisted on ia64, ppc64 and parisc64 When I replaced kasprintf("%pf") with a direct call to sprint_symbol_no_offset I must have broken the initcall blacklisting feature on the arches where dereference_function_descriptor() is non-trivial.
