From b836554386cc77f31ab43a8492a2587e0c51d51e Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Tue, 29 Nov 2016 20:28:31 +0100 Subject: x86/tsc: Fix broken CONFIG_X86_TSC=n build Add the missing return statement to the inline stub tsc_store_and_check_tsc_adjust() and add the other stubs to make a SMP=y,TSC=n build happy. While at it, remove the unused variable from the UP variant of tsc_store_and_check_tsc_adjust().
