Peter Zijlstra 9397fa2ea3 clocksource: hyper-v: Adjust hv_read_tsc_page_tsc() to avoid special casing U64_MAX ... Currently hv_read_tsc_page_tsc() (ab)uses the (valid) time value of U64_MAX as an error return. This breaks the clean wrap-around of the clock. Modify the function signature to return a boolean state and provide another u64 pointer to store the actual time on success. This obviates the need to steal one time value and restores the full counter width.
