From 9686e431c683ee7b8aca0f3985c244aee3d9f30d Mon Sep 17 00:00:00 2001 From: Christophe Leroy Date: Thu, 1 Oct 2020 12:42:44 +0000 Subject: powerpc/time: Make get_tb() common to PPC32 and PPC64 mftbu() is always defined now, so the #ifdef can be removed and replaced by an IS_ENABLED(CONFIG_PPC64) inside the PPC32 version of get_tb().
