__timekeeping_inject_sleeptime__timekeeping_inject_sleeptime - Internal function to add sleep interval*@delta: pointer to a timespec delta value* Takes a timespec offset measuring a suspend interval and properly* adds the sleep offset to the timekeeping variables.
common_timer_getGet the time remaining on a POSIX.1b interval timer. This function* is ALWAYS called with spin_lock_irq on the timer, thus it must not* mess with irq.* We have a couple of messes to clean up here. First there is the case
common_timer_setSet a POSIX.1b interval timer.
posix_cpu_timer_setGuts of sys_timer_settime for CPU timers.* This is called with the timer locked and interrupts disabled.* If we return TIMER_RETRY, it's necessary to release the timer's lock* and try again. (This happens when the timer is in the middle of firing.)
