[ Upstream commit c8f5caec3df84a02b937d6d9cda1f7ffa8dc443f ]
The cpuidle drivers' ->enter() methods are supposed to be IRQ invariant:
5e26aa933911 ("cpuidle/poll: Ensure IRQs stay disabled after cpuidle_state::enter() calls")
bb7b11258561 ("cpuidle: Move IRQ state validation")
Do that in the haltpoll driver too.
Fixes: 5e26aa933911 ("cpuidle/poll: Ensure IRQs stay disabled after cpuidle_state::enter() calls")
Closes: https://bugzilla.kernel.org/show_bug.cgi?id=218245
