set_rtc_mmss: show warning message only once

2011-01-13T16:03:07Z

Occasionally the system gets into a state where the CMOS clock has gotten slightly ahead of current time and the periodic update of RTC fails. The message is a nuisance and repeats spamming the log. See: http://www.ntp.org/ntpfaq/NTP-s-trbl-spec.htm#Q-LINUX-SET-RTC-MMSS Rather than just removing the message, make it show only once and reduce severity since it indicates a normal and non urgent condition.

CRIS: GENERIC_TIME fixes

2010-08-04T10:58:55Z

GENERIC_TIME was not functional for CRIS, giving random backward time jumps. For CRISv32 implement a new clocksource using the free running counter and ditch the arch_gettimeoffset. The random time jumps still existed, but turned out to be the write_seqlock which was missing around our do_timer() call. So switch over to GENERIC_TIME using the clocksource for CRISv32. CRISv10 doesn't have the free running counter needed for the clocksource trick, but we can still use GENERIC_TIME with arch_gettimeoffset. Unfortunately, there were problems in using the prescaler register to timer0 for the gettimeoffset calculation, so it is now ignored, making our resolution worse by the tune of 40usec (0.4%) worst case. At the same time, clean up some formatting and use NSEC_PER_SEC instead of 1000000000. Signed-off-by: Jesper Nilsson

cris: Convert cris to use read/update_persistent_clock

2010-03-13T00:14:13Z

This patch converts the cris architecture to use the generic read_persistent_clock and update_persistent_clock interfaces, reducing the amount of arch specific code we have to maintain, and allowing for further cleanups in the future. I have not built or tested this patch, so help from arch maintainers would be appreciated.

CRIS: Add sched_clock to kernel/time.c

2008-02-08T10:06:37Z

Also, clean up some whitespace errors.

cris build fixes: fixes in arch/cris/kernel/time.c

[PATCH] CRIS: local_irq_disable() is redundant after local_irq_save()

2007-02-11T18:51:20Z

arch/cris/arch-v10/kernel/time.c::get_ns_in_jiffie() contains local_irq_disable() call after local_irq_save(). This looks redundant. arch/cris/kernel/time.c::do_gettimeofday() contains local_irq_disable() call after local_irq_save(). This looks redundant.
