These cleanup patches are mainly move stuff around and should all
be harmless. They are mainly split out so that other branches can
be based on top to avoid conflicts.
Notable changes are:
* We finally remove all mach/timex.h, after CLOCK_TICK_RATE is no
longer used. (Uwe Kleine-König)
* The Qualcomm MSM platform is split out into legacy mach-msm and
new-style mach-qcom, to allow easier maintainance of the new
hardware support without regressions. (Kumar Gala)
* A rework of some of the Kconfig logic to simplify multiplatform
support (Rob Herring)
* Samsung Exynos gets closer to supporting multiplatform (Sachin
Kamat and others)
* mach-bcm3528 gets merged into mach-bcm (Stephen Warren)
* at91 gains some common clock framework support (Alexandre Belloni,
Jean-Jacques Hiblot and other French people).

This option enables support for event stream generation based on

the ARM architected timer. It is used for waking up CPUs executing
|

the wfe instruction at a frequency represented as a power-of-2
|
|
divisor of the clock rate.
|
|
The main use of the event stream is wfe-based timeouts of userspace
|
|
locking implementations. It might also be useful for imposing timeout
|
|
on wfe to safeguard against any programming errors in case an expected
|
|
event is not generated.

This must be disabled for hardware validation purposes to detect any

hardware anomalies of missing events.
