The sead3-mtd.o is built for obj-y -- and hence this code is always
present. It will never be modular, so using module_init as an alias
for __initcall can be somewhat misleading.
Fix this up now, so that we can relocate module_init from
init.h into module.h in the future. If we don't do this, we'd
have to add module.h to obviously non-modular code, and that
would be a worse thing.
Note that direct use of __initcall is discouraged, vs. one
of the priority categorized subgroups. As __initcall gets
mapped onto device_initcall, our use of device_initcall
directly in this change means that the runtime impact is
zero -- it will remain at level 6 in initcall ordering.
We also fix a missing semicolon, which this change uncovers.

None of these files are actually using any __init type directives
and hence don't need to include <linux/init.h>. Most are just a
left over from __devinit and __cpuinit removal, or simply due to
code getting copied from one driver to the next.

we want the device tree to be unflattened into non init memory so it can be
accessed later by, for example, a probing function of a driver module.

The defaults are not always applicable and it makes it hard for the bootloader
to override them. By removing it we give the bootloader full control over what
command line parameters to pass.
Without this change we will need to modify the built-in dtb to add bootloader
cmd line parameters or do some work to append them after we unflatten the device
tree.
Sead3 is a development board, that's why we want to be able to change boot
parameters on the fly from the bootloader.

commit 3747069b25e419f6b51395f48127e9812abc3596 upstream.
The __cpuinit type of throwaway sections might have made sense
some time ago when RAM was more constrained, but now the savings
do not offset the cost and complications. For example, the fix in
commit 5e427ec2d0 ("x86: Fix bit corruption at CPU resume time")
is a good example of the nasty type of bugs that can be created
with improper use of the various __init prefixes.
After a discussion on LKML[1] it was decided that cpuinit should go
the way of devinit and be phased out. Once all the users are gone,
we can then finally remove the macros themselves from linux/init.h.
Note that some harmless section mismatch warnings may result, since
notify_cpu_starting() and cpu_up() are arch independent (kernel/cpu.c)
and are flagged as __cpuinit -- so if we remove the __cpuinit from
the arch specific callers, we will also get section mismatch warnings.
As an intermediate step, we intend to turn the linux/init.h cpuinit
related content into no-ops as early as possible, since that will get
rid of these warnings. In any case, they are temporary and harmless.
Here, we remove all the MIPS __cpuinit from C code and __CPUINIT
from asm files. MIPS is interesting in this respect, because there
are also uasm users hiding behind their own renamed versions of the
__cpuinit macros.

The soft reset register address and reset value to be written are
incorrect for the SEAD-3 platform. This patch fixes them such that
the SEAD-3 can actually perform a soft reset instead of causing an
exception. Also remove usage of 'include/asm/mips-boards/generic.h'
header file.

Setting the LED_CORE_SUSPENDRESUME flag causes the LED driver core to call
led_classdev_suspend/led_classdev_resume during suspend/resume. Since this is
exactly what the driver's custom suspend/resume callbacks do we can replace them
by setting the LED_CORE_SUSPENDRESUME flag.

CONFIG_HOTPLUG is going away as an option. As a result, the __dev*
markings need to be removed.
This change removes the use of __devinit, __devexit_p, __devinitdata,
and __devexit from these drivers.
Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.
