Subject: [PATCH] init/main.c: fix initcall_blacklisted on ia64, ppc64 and parisc64
Date: Wed, 15 Jun 2016 23:48:01 +0200
Message-ID: <1466027283-4065-1-git-send-email-linux@rasmusvillemoes.dk> (raw)
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.
Fixes: c8cdd2be213f (init/main.c: simplify initcall_blacklisted())
