start_kernel
|-> setup_arch
|-> x86_init.oem.arch_setup = xen_arch_setup
....
|-> check_bugs
|-> identify_boot_cpu
|-> identify_cpu
|-> select_idle_routine
so xen_arch_setup will set pm_idle and select_idle_routine will honour
it. I'm being told this is run either in the dom0 or the paravirt guest
and if so, I don't see any issue with this for baremetal. So you can
have my ACK provided this is tested on baremetal too.
Thanks.
