Subject: [PATCH] tools/misc/xenpm: fix getting info when some CPUs are offline
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

Use physinfo.max_cpu_id instead of physinfo.nr_cpus to get max CPU id.
This fixes for example 'xenpm get-cpufreq-para' with smt=off, which
otherwise would miss half of the cores.
