Subject: [PATCH] virsh: use correct sizeof when allocating cpumap
Bug: https://bugzilla.redhat.com/show_bug.cgi?id=878376
Found by coverity:
Error: SIZEOF_MISMATCH (CWE-569):
libvirt-0.10.2/tools/virsh-domain.c:4754: suspicious_sizeof: Passing
argument "8UL /* sizeof (cpumap) */" to function
"_vshCalloc(vshControl *, size_t, size_t, char const *, int)" and
then casting the return value to "unsigned char *" is suspicious.
