[PATCH] xen,tools: pincpu use vcpu and cpumap_t
The following patch updates the dom0 pincpu operation to read the VCPU
value from the xend interface rather than hard-coding the exec_domain to
0. This prevented pinning VCPUS other than 0 to a particular cpu. The
pincpu cpu argument is replaced with cpumap, a u64 bitmap representing
which CPUs a VCPU can use.
I added the number of VCPUS to the main xm list output and also included
a new sub-option to xm list to display the VCPU to CPU mapping. While
working on the pincpu code, I fixed an out-of-bounds indexing for the
pincpu operation that wasn't previously exposed since the
vcpu/exec_domain value was hard-coded to 0.
