[Xen-devel] CALL_FUNCTION broadcast vs. a set of cpus

["Dong, Eddie" <eddie.dong@xxxxxxxxx>]

Ian/Kier:
        Current implementation of CALL_FUNCTION is broadcasting IPI to
all but self. For VMX domain, in some situation like vcpu migration, we
need call function to specified target processor only like VMCS register
dump. I am curious if you'd like to see an additional parameter
(cpu_mask) for smp_call_function and minor modification to
smp_call_function_interrupt to support this? Or do you prefer to add a
new function with similar function but targeting specified cpus?
        Thanks,eddie
