cpuidle: replace xen access to x86 pm_idle and default_idle
When a Xen Dom0 kernel boots on a hypervisor, it gets access to the raw-hardware ACPI tables. While it parses the idle tables for the hypervisor's beneift, it uses HLT for its own idle. Rather than have xen scribble on pm_idle and access default_idle, have it simply disable_cpuidle() so acpi_idle will not load and architecture default HLT will be used. cc: [email protected] Tested-by: Konrad Rzeszutek Wilk <[email protected]> Acked-by: H.
