From 6474924e2b5ddb0030c355558966adcbe3b49022 Mon Sep 17 00:00:00 2001 From: Tobias Klauser Date: Wed, 28 Jun 2017 15:30:02 +0200 Subject: arch: remove unused macro/function thread_saved_pc() The only user of thread_saved_pc() in non-arch-specific code was removed in commit 8243d5597793 ("sched/core: Remove pointless printout in sched_show_task()"). Remove the implementations as well. Some architectures use thread_saved_pc() in their arch-specific code. Leave their thread_saved_pc() intact.
