by using the flag and the new cpumap arguments introduced in
the parameters of the DOMCTL_{get,set}_vcpuaffinity hypercalls.
Now, both xc_vcpu_setaffinity() and xc_vcpu_getaffinity() have
a new flag parameter, to specify whether the user wants to
set/get hard affinity, soft affinity or both. They also have
two cpumap parameters instead of only one. This way, it is
possible to set/get both hard and soft affinity at the same
time (and, in case of set, each one to its own value).
In xc_vcpu_setaffinity(), the cpumaps are IN/OUT parameters,
as it is for the corresponding arguments of the
DOMCTL_set_vcpuaffinity hypercall. What Xen puts there is the
hard and soft effective affinity, that is what Xen will actually
use for scheduling.
In-tree callers are also fixed to cope with the new interface.
