This reverts commit da788acb28.
That commit tried to fix the section mismatch warning by moving the
ppc_corenet_clk_driver struct to init section. This is definitely wrong
because the kernel would free the memories occupied by this struct
after boot while this driver is still registered in the driver core.
The kernel would panic when accessing this driver struct.

While DIV6 clocks require the divisor field to be non-zero when stopping
the clock, some clocks (e.g. ZB on sh73a0) fail to be re-enabled later
if the divisor field is changed when stopping the clock.
The reason for this is unknown.
To fix this, do not touch the divisor field if it's already non-zero.
On kzm9g, the smsc911x Ethernet controller is connected to the sh73a0
Bus State Controller, which is clocked by the ZB clock. Without this
fix, if the ZB clock is disabled during system suspend, and re-enabled
during resume, the kernel locks up when the smsc911x driver tries to
access the Ethernet registers.

We've been seeing some crashes at resume time on rk3288-based systems.
On some machines they simply never wake up from suspend. Symptoms
include:
- System clearly got to sleep OK. Power consumption is low, the PWM
for the PWM regulator has stopped, and the "global_pwroff" output
shows that the system is down.
- When system tries to wake up power consumption goes up.
- No kernel resume code (which was left in PMU SRAM) ran. We added
some basic logging to this code (write to a location in SRAM right
at resume time) and didn't see the logging run.
It appears that we can fix the problem by slowing down APLL before we
suspend. On the system I tested things seemed reliable if I disabled
1.8GHz and 1.7GHz. The Mask ROM itself tries to slow things down
(which is why PLLs are in slow mode by the time we get to the kernel),
but apparently it is crashing before it even gets there.
We'll be super paranoid and not just go down to 1.6GHz but we'll match
what the Mask ROM seems to be doing and go into slow mode. We'll also
be safe and put all PLLs (not just APLL) into slow mode (well, except
DPLL which is needed for SDRAM). We'll even put NPLL into slow mode
which the Mask ROM didn't do (not that it's used for much important
stuff at early resume time).
Note that the old Rockchip reference code did something just like
this, though they jammed it into pm.c instead of putting it in the
syscore ops of the clock driver.

are of the (n+1) type.
The rk3066 and rk3188 socs use more complex divider types making it
necessary for the list-elements to be the real register-values to write.
Therefore reduce divider values in the table accordingly so that they
really are the values that should be written to the registers and match
the dividers actually specified for the rk3288.

This kind of boot hang was observed on Arndale Octa and Peach Pi/Pit

folks opened the flood gates.

- Fixes and optimization to the microMIPS support.
- Option to disable the FTLB.
- Dump more relevant information on machine check exception
- Change binfmt to allow arch to examine PT_*PROC headers
- Support for new style FPU register model in O32
- VDSO randomization.

Merge tag 'for-v3.19-exynos-clk-2' of git://linuxtv.org/snawrocki/samsung into clk-next
- exynos4415 and exynos audio subsystem clk driver (build
with PM_SLEEP disabled, resource release) fixes
- minor cleanups in drivers/clk/samsung/clk.c (spelling,
includes)
- modification of the exynos4 HDMI PHY clock definition to
model dependency of "sclk_hdmiphy" on the "hdmi" clock
Fixes the following sparse warnings:
drivers/clk/mmp/clk-frac.c:113:6: warning:
symbol 'clk_factor_init' was not declared. Should it be static?

These are changes for drivers that are intimately tied to some SoC
and for some reason could not get merged through the respective
subsystem maintainer tree.
The largest single change here this time around is the Tegra
iommu/memory controller driver, which gets updated to the new
iommu DT binding. More drivers like this are likely to follow
for the following merge window, but we should be able to do
those through the iommu maintainer.
Other notable changes are:
* reset controller drivers from the reset maintainer (socfpga, sti, berlin)
* fixes for the keystone navigator driver merged last time
* at91 rtc driver changes related to the at91 cleanups
* ARM perf driver changes from Will Deacon
* updates for the brcmstb_gisb driver
