This reverts commit 99b69db57544ec7ed427607f1a2a1858a7d43b61 Core-for-CI:ICL_only Disable ACPI idle driver. This hack has been provided considering the Bug assessment that ACPI idle driver page fault causes below bug. FDO https://bugs.freedesktop.org/show_bug.cgi?id=108840 But this bug is still reproducible after disabling ACPI idle driver. It looks "rcu_preempt self-detected stall on CPU" causes to hung kworker and followed by panic resulted this bug. Hence it make sense to revert this patch.
