If two consecutive reads of the counter are the same, it is also not an overflow. "systimel_1 < systimel_2" should be "systimel_1 <= systimel_2". Before the patch, we could perform an *erroneous* correction: Let's say that systimel_1 == systimel_2 == 0xffffffff. "systimel_1 < systimel_2" is false, we think it's an overflow, we read "systimeh = er32(SYSTIMH)" which meanwhile had incremented, and use "(systimeh << 32) + systimel_2" value which is 2^32 too large.
