[PATCH v4 0/6] Support calling functions on dedicated physical cpu
Some hardware (e.g. Dell Studio laptops) require special functions to
be called on physical cpu 0 in order to avoid occasional hangs. When
running as dom0 under Xen this could be achieved only via special boot
parameters (vcpu pinning) limiting the hypervisor in it's scheduling
decisions.

Hmm, couldn't get one which needs smm to be called on cpu 0.
OTOH I've done various tests and added a printk() in raise_smm()
and i8k_smm_func() issuing the cpu number it was called on.
