cpuidle: haltpoll: Do not enable interrupts when entering idle

[ Upstream commit c8f5caec3df84a02b937d6d9cda1f7ffa8dc443f ]

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

cpuidle: haltpoll: Do not enable interrupts when entering idle

[ 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")

that driver with arch_cpu_idle() to allow MWAIT to be used (Li
RongQing)

- Add Emerald Rapids Xeon support to the intel_idle driver (Artem
Bityutskiy)

- Add ARCH_SUSPEND_POSSIBLE dependencies for ARMv4 cpuidle drivers to
avoid randconfig build failures (Arnd Bergmann)

- Make kobj_type structures used in the cpuidle sysfs interface
constant (Thomas Weißschuh)

- Make the cpuidle driver registration code update microsecond values
of idle state parameters in accordance with their nanosecond values
if they are provided (Rafael Wysocki)

- Make the PSCI cpuidle driver prevent topology CPUs from being
suspended on PREEMPT_RT (Krzysztof Kozlowski)

- Document that pm_runtime_force_suspend() cannot be used with
DPM_FLAG_SMART_SUSPEND (Richard Fitzgerald)

- Add EXPORT macros for exporting PM functions from drivers (Richard
Fitzgerald)

- Remove /** from non-kernel-doc comments in hibernation code (Randy
Dunlap)

- Fix possible name leak in powercap_register_zone() (Yang Yingliang)

- Add Meteor Lake and Emerald Rapids support to the intel_rapl power
capping driver (Zhang Rui)

- Modify the idle_inject power capping facility to support 100% idle
injection (Srinivas Pandruvada)

- Fix large time windows handling in the intel_rapl power capping
driver (Zhang Rui)

- Fix memory leaks with using debugfs_lookup() in the generic PM
domains and Energy Model code (Greg Kroah-Hartman)

- Add missing 'cache-unified' property in the example for kryo OPP
bindings (Rob Herring)

- Fix error checking in opp_migrate_dentry() (Qi Zheng)

- Let qcom,opp-fuse-level be a 2-long array for qcom SoCs (Konrad
Dybcio)

path (Ross Zwisler)

- Correct spelling problems for Documentation/power/ as reported by
codespell (Randy Dunlap)"

cpuidle-haltpoll: Replace default_idle() with arch_cpu_idle()

cpuidle-haltpoll: Replace default_idle() with arch_cpu_idle()

When a KVM guest has MWAIT, mwait_idle() is used as the default idle
function.

However, the cpuidle-haltpoll driver calls default_idle() from
default_enter_idle() directly and that one uses HLT instead of MWAIT,
which may affect performance adversely, because MWAIT is preferred to
HLT as explained by the changelog of commit aebef63cf7ff ("x86: Remove
vendor checks from prefer_mwait_c1_over_halt").

Make default_enter_idle() call arch_cpu_idle(), which can use MWAIT,
instead of default_idle() to address this issue.
