4c3ffffdbc ARM: Push selects for TWD/SCU into machine entries
The TWD and SCU configs are selected by default as long as
MSM_SCORPIONMP is false and/or MCT is false. Implementing the
logic this way certainly saves lines in the Kconfig but it
precludes those machines which select MSM_SCORPIONMP or MCT from
participating in the single zImage effort because when those
machines are combined with other SMP capable machines the TWD and
SCU are no longer selected by default.

Push the select out to the machine entries so that we can compile
these machines together and still select the appropriate configs.

2bb4b70b1d ARM: imx: provide twd clock lookup from device tree
While booting from device tree, imx6q used to provide twd clock lookup
by calling clk_register_clkdev() in clock driver.  However, the commit
bd60345 (ARM: use device tree to get smp_twd clock) forces DT boot to
look up the clock from device tree.  It causes the failure below when
twd driver tries to get the clock, and hence kernel has to calibrate the
local timer frequency.

 smp_twd: clock not found -2
 ...
 Calibrating local timer... 396.13MHz.

Fix the regression by providing twd clock lookup from device tree, and
remove the unused twd clk_register_clkdev() call from clock driver.

cab1e0a36c ARM: clk-imx35: Bugfix iomux clock
This patch enables iomuxc_gate clock. It is necessary to be able to
reconfigure iomux pads. Without this clock enabled, the
clk_disable_unused function will disable this clock and the iomux pads
are not configurable anymore. This happens at every boot. After a reboot
(watchdog system reset) the clock is not enabled again, so all iomux pad
reconfigurations in boot code are without effect.

The iomux pads should be always configurable, so this patch always
enables it.

b43a7ffbf3 cpufreq: Notify all policy->cpus in cpufreq_notify_transition()
policy->cpus contains all online cpus that have single shared clock line. And
their frequencies are always updated together.

Many SMP system's cpufreq drivers take care of this in individual drivers but
the best place for this code is in cpufreq core.

This patch modifies cpufreq_notify_transition() to notify frequency change for
all cpus in policy->cpus and hence updates all users of this API.

fb5d932ac2 The imx fixes for 3.9, take 4:
Running suspend/resume without no_console_suspend setting on kernel
 cmdline will likely makes system hang.  It causesd by the sync issue
 between imx_cpu_die() and imx_cpu_kill() call.  Fix the issue by
 synchronizing the calls using cpu jumping argument register which is
 free to use in kernel.

c0114709ed irqchip: gic: Perform the gic_secondary_init() call via CPU notifier
All the calls to gic_secondary_init() pass 0 as the first argument.
Since this function is called on each CPU when starting, it can be done
in a platform-independent way via a CPU notifier registered by the GIC
code.
