I also don't know much details of the mwait setting for cpu idle, and
can not reproduce the ops on my box. Most of time the nhm box is just hang.
Maybe BIOS setting have bugs and your change is just expose them.
but it is clear inappropriate to change percpu cstate to a unified
unique value, while left lots of percpu struct service for this. A
example of x86, you can look into arch/x86/kernel/acpi/cstate.c and
other acpi head files.
