Andy Shevchenko	4a7bba1df0	percpu: add a test case for the specific 64-bit value addition It might be a corner case when we add UINT_MAX as 64-bit unsigned value to the percpu variable as it's not the same as -1 (ULONG_LONG_MAX). Add a test case for that.

percpu: add a test case for the specific 64-bit value addition

It might be a corner case when we add UINT_MAX as 64-bit unsigned value to
the percpu variable as it's not the same as -1 (ULONG_LONG_MAX).  Add a
test case for that.
