These differences in Python 3 were causing errors: - xrange is replaced by range - dict values are a view (instead of list) - has_key is removed Fixes:deb87e6777("usertools: use sysfs for CPU layout") Fixes:63985c5f10("usertools: fix CPU layout for more than 2 threads") Signed-off-by: Thomas Monjalon <thomas@monjalon.net> Reviewed-by: Gowrishankar Muthukrishnan <gowrishankar.m@linux.vnet.ibm.com>
