This folds update_ntp_one_tick() into second_overflow() and adds time_adjust to the tick length, this makes time_next_adjust unnecessary. This slightly changes the adjtime() behaviour, instead of applying it to the next tick, it's applied to the next second.

This converts time_offset into a scaled per tick value. This avoids now completely the crude compensation in second_overflow().

This introduces ntp_update_frequency() and deinlines ntp_clear() (as it's not performance critical). ntp_update_frequency() calculates the base tick length using tick_usec and adds a base adjustment, in case the frequency doesn't divide evenly by HZ.

The lock annotation macros __acquires, __releases, __acquire, and __release all currently throw away the lock expression passed as an argument. Now that sparse can parse __context__ and __attribute__((context)) with a context expression, pass the lock expression down to sparse as the context expression. This requires a version of sparse from GIT commit 37475a6c1c3e66219e68d912d5eb833f4098fd72 or later.

If the driver has interrupts available to it, there is really no reason to have a kernel daemon push the IPMI state machine. Note that I have experienced machines where the interrupts do not work correctly. This was a long time ago and hopefully things are better now. If some machines still have broken interrupts, a blacklist will need to be added.

This lets the at91rm9200 RTC alarm be a system wakeup irq, according to the setting of /sys/devices/platform/at91_rtc/power/wakeup.

The rtc_is_valid_tm() routine needs to treat some of the fields it checks as unsigned, to prevent wrongly accepting invalid rtc_time structs; this is the same approach used elsewhere in the RTC code for such tests. Conversely, rtc_proc_show() is missing one invalid-day-of-month test that rtc_is_valid_tm() makes: there is no day zero.

This makes RTC core components use "subsys_init" instead of "module_init", as appropriate for subsystem infrastructure. This is mostly useful for statically linking drivers in other parts of the tree that may provide an RTC interface as a secondary functionality (e.g. part of a multifunction chip); they won't need to worry so much about drivers/Makefile link order.

Small updates to make the RTC class Kconfig text be more informative. This should help folk used to the drivers/char/rtc.c support, or a single RTC, be slightly less surprised by the differences. Also, adds a new RTC_DEBUG option to predefine DEBUG in the framework and its drivers, while debugging. That's getting to be a standard idiom, and it's pretty useful.
