From c887ef5707591e84f80271e95e99ff9fb38987b5 Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Thu, 28 May 2020 00:58:43 +1000 Subject: [PATCH] powerpc/64s: Don't set FSCR bits in INIT_THREAD Since the previous commit that saves the value of FSCR configured at boot into init_task.thread.fscr, the static initialisation in INIT_THREAD now no longer has any effect. So remove it. For non DT CPU features, the end result is the same, because __init_FSCR() is called on all CPUs that have an FSCR (Power8, Power9), and it sets FSCR_TAR & FSCR_EBB.
