Fix example error_injection_tool
I got a "sched_setaffinity:: Invalid argument" error when using err_injection_tool to inject error on a system with over 32 cpus. Error information when injecting an error on a system with over 32 cpus: $ ./err_injection_tool -i /sys/devices/system/cpu/cpu0/err_inject//err_type_info Begine at Tue Mar 26 11:20:08 2013 Configurations: On cpu32: loop=10, interval=5(s) err_type_info=4101,err_struct_info=95 Error sched_setaffinity:: Invalid argument All done This because there is overflow when calculating the cpumask: the type of (1<<k) is int, while mask[j] is unsigned long. When k > 31, (1<<k) is truncated to ZERO, resulting in a unexpected cpumask. Signed-off-by: Xie XiuQi <xiexiuqi@huawei.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
