When booted with nohz_full and lockdep, these things go off. This is because the entry code is calling some of the C handlers before ct_user_exit. Patch 2 is for consistency, it doesn't look like anything minds this today. Thanks, James Morse (2): arm64: entry: Move ct_user_exit before any user of RCU arm64: entry: Move ct_user_exit before we can take another exception arch/arm64/kernel/entry.S | 32 +++++++++++++++++--------------- 1 file changed, 17 insertions(+), 15 deletions(-) -- 2.20.1 _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
