Use os::active_processor_count() in G1 code instead of os::processor_count()
Here is David Holmes comment to the JDK-8147095:
/os::processor_count() is set to the number of logical processors
configured on a system (exact definition varies by platform). With the
use of CPU sets, resource pools, and other affinity based mechanisms
this can be a much larger value than the number of CPUs available for
the VM to use. /
/The number of CPUs currently available for the VM to use should be
reported through os::active_processor_count().
