Impact: change calling convention of existing clock_event APIs
struct clock_event_timer's cpumask field gets changed to take pointer,
as does the ->broadcast function.
Another single-patch change. For safety, we BUG_ON() in
clockevents_register_device() if it's not set.

This just leaves include/asm-arm/plat-* to deal with.

Update AT91SAM9/CAP9 PIT driver to use generic time and clockevent
infrastructure:
- Clocksource gives sub-microsecond timestamp precision, assuming
memory is clocked at over 16 MHz. It's less than a 32 bit counter,
unless it's is also generating IRQs.
- Clockevent device supports periodic mode only; no oneshot
support from this hardware. No IRQs generated unless it's the
active clocksource.
Later, another timer (probably from a TC module) can provide a oneshot
clockevent device to get NO_HZ and High-Res-Timer behavior.
This also updates the timekeeping to use the actual master clock rate
on the system, instead of compile-time <asm/arch/timex.h> constants
matching what Atmel's EK boards use. (Product boards may well differ!)
Plus cleanup: rename "*_timer*" symbols to "*_pit*" (there are other
timers, but only one PIT); shorter lines; remove needless CPP stuff;
make several symbols static; etc.

Fix an overrun in the AT91SAM9 gettimeoffset() function. This causes
the time value returned by gettimeofday() to jump "backwards".

Now that Linux includes support for the Atmel AT91SAM9260 and
AT91SAM9261 processors in addition to the original Atmel AT91RM9200
(with support for more AT91 processors pending), the "mach-at91rm9200"
and "arch-at91rm9200" directories should be renamed to indicate their
more generic nature.
The following git commands should be run BEFORE applying this patch:
git-mv arch/arm/mach-at91rm9200 arch/arm/mach-at91
git-mv include/asm-arm/arch-at91rm9200 include/asm-arm/arch-at91
