3.5.7.31 -stable review patch. If anyone has any objections, please let me know. ------------------ From: Colin Cross <ccross@xxxxxxxxxxx> get_monotonic_boottime adds three nanonsecond values stored in longs, followed by an s64. If the long values are all close to 1e9 the first three additions can overflow and become negative when added to the s64. Cast the first value to s64 so that all additions are 64 bit.
