Pull module_init replacement part one from Paul Gortmaker:
"Replace module_init with equivalent device_initcall in non modules.
This series of commits converts non-modular code that is using the
module_init() call to hook itself into the system to instead use
device_initcall().
The conversion is a runtime no-op, since module_init actually becomes
__initcall in the non-modular case, and that in turn gets mapped onto
device_initcall. A couple files show a larger negative diffstat,
representing ones that had a module_exit function that we remove here
vs previously relying on the linker to dispose of it.
We make this conversion now, so that we can relocate module_init from
init.h into module.h in the future.
The files changed here are just limited to those that would otherwise
have to add module.h to obviously non-modular code, in order to avoid
a compile fail, as testing has shown"

The X86_INTEL_MID option is bool, and hence this code is either
present or absent. It will never be modular, so using
module_init as an alias for __initcall is rather 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.

MID has no PIC, but depending on the platform it requires the
abt_timer, which is connected to irq0. The timer is set up at
late_time_init().
But, looking at the MID code it seems, that there is no reason to do
so. The only code which might need the timer working is the TSC
calibration code, but thats a non issue on MID as that is using its
own empty calibration function. And check_timer() is not invoked
either because MID has no PIC and therefor no legacy irqs.
So if you look at intel_mid_time_init() then you'll see that in the
ARAT case the timer setup is skipped already. So until the point where
x86_init.timers.setup_percpu_clockev() is called for the boot cpu
nothing really needs a timer on MID.
According to the MID code the apbt horror is only used for moorestown.
Medfield and later use the local apic timer without the apbt nonsense.
The best thing we can do is to drop moorestown support and get rid of
that apbt nonsense alltogether.
I don't think anyone deeply cares about it not being supported from
3.18 on. The number of devices which sport a moorestown should be
pretty limited and the only relevant use case of those is to act as a
pocket heater with short battery life time. Its pretty pointless to
update kernels on pocket heaters except for bragging reasons.
If someone at Intel really thinks that we need to keep moorestown
alive for other than documentary and sentimental reasons, then we can
move the apbt setup to x86_init.timers.setup_percpu_clockev(). At that
point the IOAPIC is setup already, so it should just work.

This was used on SFI (Medfield, Clovertrail) based platforms as well, though
new ones use normal serial interface for the console service.

In order make the driver more portable and support other Intel MID
(Mobile Internet Device) platforms we need to move Medfield code from
intel-mid.c core to its own mfld.c file.
This patch contains no functional changes.

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.

The commit 712b6aa8731a7e148298c58cea66a5209c659e3c [Nov7 linux-next
via tip/auto-latest] ("intel_mid: Renamed *mrst* to *intel_mid*")
adds a __cpuinit.
We removed this a couple versions ago; we now want to remove
the compat no-op stubs. Introducing new users is not what
we want to see at this point in time, as it will break once
the stubs are gone.

As Intel rolling out more SoC's after Moorestown, we need to
re-structure the code in a way that is backward compatible and easy to
expand. This patch implements a flexible way to support multiple boards
and devices.
This patch does not add any new functional support. It just refactors
the existing code to increase the modularity and decrease the code
duplication for supporting multiple soc's and boards.
Currently intel-mid.c has both board and soc related code in one file.
This patch moves the board related code to new files and let linker
script to create SFI devite table following this:
1. Move the SFI device specific code to
arch/x86/platform/intel-mid/device-libs/platform_<device>.*
A new device file is added for every supported device. This code will
get conditionally compiled by using corresponding device driver
CONFIG option.
2. Move the device_ids location to .x86_intel_mid_dev.init section by
using new sfi_device() macro.
This patch was based on previous code from Sathyanarayanan Kuppuswamy.

Intel mid sfi code doesn't need struct devs_id.get_platform_data != NULL.
If the callback is not set, just assume there is no platform_data.

Moved SFI specific parsing/handling code to sfi.c. This will enable us
to reuse our intel-mid code for platforms that supports firmware
interfaces other than SFI (like ACPI).

This patch provides a means to add custom handler for
SFI devices. If you set device_handler as NULL in
device_id table standard SFI device handler will be used.
If its not NULL custom handler will be called.

SFI device_id[] table parsing code is duplicated in every SFI
device handler. This patch removes this code duplication, by
adding a seperate function get_device_id() to parse through the
device table. Also this patch moves the SPI, I2C, IPC info code from
sfi_parse_devs() to respective device handlers.

mrst is used as common name to represent all intel_mid type
soc's. But moorsetwon is just one of the intel_mid soc. So
renamed them to use intel_mid.
This patch mainly renames the variables and related
functions that uses *mrst* prefix with *intel_mid*.
To ensure that there are no functional changes, I have compared
the objdump of related files before and after rename and found
the only difference is symbol and name changes.

Following files contains code that is common to all intel mid
soc's. So renamed them as below.
mrst/mrst.c -> intel-mid/intel-mid.c
mrst/vrtc.c -> intel-mid/intel_mid_vrtc.c
mrst/early_printk_mrst.c -> intel-mid/intel_mid_vrtc.c
pci/mrst.c -> pci/intel_mid_pci.c
Also, renamed the corresponding header files and made changes
to the driver files that included these header files.
To ensure that there are no functional changes, I have compared
the objdump of renamed files before and after rename and found
that the only difference is file name change.
