Hi,

this is the last batch I have to enable PREEMPT_RT on the ARM
architecture.
Last time I posted them there was some discussion about making the
branch predictor hardening worse. I redid it hoping it improved now and
does not make it worse.

Sebastian Andrzej Siewior (3):
  ARM: mm: fault: Move harden_branch_predictor() before interrupts are
    enabled
  arm: Disable FAST_GUP on PREEMPT_RT if HIGHPTE is also enabled.
  ARM: Allow to enable RT

Thomas Gleixner (1):
  arm: Disable jump-label on PREEMPT_RT.

Yadi.hu (1):
  ARM: mm: fault: Enable interrupts before invoking __do_user_fault()
