+Subject: sched: declare pid_alive as inline
+
+From: Richard Guy Briggs <rgb@redhat.com>
+
+commit 80e0b6e8a001361316a2d62b748fe677ec46b860 upstream.
+
+We accidentally declared pid_alive without any extern/inline connotation.
+Some platforms were fine with this, some like ia64 and mips were very angry.
+If the function is inline, the prototype should be inline!
+
+on ia64:
+include/linux/sched.h:1718: warning: 'pid_alive' declared inline after
+being called
