[PATCH 0/2 resend] show isolated & nohz_full cpus in sysfs

From: riel

Currently there is no good way to get the isolated and nohz_full
CPUs at runtime, because the kernel may have changed the CPUs
specified on the commandline (when specifying all CPUs as
isolated, or CPUs that do not exist, ...)

This series adds two files to /sys/devices/system/cpu, which can
be used by system management tools like libvirt, openstack, etc.
to ensure proper task placement.

These patches were kind of (but not formally) acked by
Mike and Frederic, see https://lkml.org/lkml/2015/3/27/852
