cpuidle: haltpoll: Do not enable interrupts when entering idle

Browse source

[ Upstream commit c8f5caec3d ]

The cpuidle drivers' ->enter() methods are supposed to be IRQ invariant:

  5e26aa9339 ("cpuidle/poll: Ensure IRQs stay disabled after cpuidle_state::enter() calls")
  bb7b112585 ("cpuidle: Move IRQ state validation")

Do that in the haltpoll driver too.

Fixes: 5e26aa9339 ("cpuidle/poll: Ensure IRQs stay disabled after cpuidle_state::enter() calls")
