/**

 * __ktime_get_real_seconds - The same as ktime_get_real_seconds

 * but without the sequence counter protect. This internal function

 * is called just when timekeeping lock is already held.

 * __ktime_get_real_seconds - Unprotected access to CLOCK_REALTIME seconds

 *

 * The same as ktime_get_real_seconds() but without the sequence counter

 * protection. This function is used in restricted contexts like the x86 MCE

 * handler and in KGDB. It's unprotected on 32-bit vs. concurrent half

 * completed modification and only to be used for such critical contexts.

 *

 * Returns: Racy snapshot of the CLOCK_REALTIME seconds value
