Convert the processor platform device setup
functions from __initcall() and sometimes
device_initcall() to arch_initcall().
This makes sure that the platform devices are
registered a bit earlier so the devices are
available when drivers register using initcall
levels earlier than device_initcall().
A good example is platform devices needed by
i2c-sh_mobile.c which registers a bit earlier
using subsys_initcall().

Convert the i2c-sh_mobile i2c bus driver to use
subsys_initcall() instead of module_init().
This change makes the driver register a bit earlier which
together with earlier platform data moves the time for probe().
The earlier probe() makes it possible to use i2c_get_adapter()
and i2c_transfer() from device_initcall().
The same strategy is used by other i2c bus drivers such as
i2c-pxa.c and i2c-s3c2410.c.

Convert the m66592-udc driver to use the on_chip flag
from platform data to enable on chip behaviour instead
of relying on CONFIG_SUPERH_BUILT_IN_M66592 ugliness.
This makes the code cleaner and also allows us to support
both external and internal m66592 with the same kernel.
It also makes the Kconfig part more future proof since
we with this patch can add support for new processors
with on-chip m66592 without modifying the Kconfig.
The patch adds a m66592 header file for platform data
and ties in platform data to the existing m66592 devices.

This patch extends the existing Samsung IrDA (0419:0001) quirk file with newly
reported variants:
* New device variants with 203 byte and 135 byte report descriptors were
reported to be recognized incorrectly. This patch adds an autodetection for
those two, using report descriptor size to enable new quirks.
* Any other unknown 0419:0001 variants will now be treated without any quirk
flags (i.e. IGNORE_HIDINPUT/HIDDEV_FORCE will not be set by default anymore).
More details:
1. Descriptor size 184 bytes ("Satelco bundled remote")
Already supported since kernel 2.6.25 (my old patch).
2. Descriptor size 203 bytes ("Optronix remote")
This receiver mostly works with the regular HID input driver. Only when some
keys are released, another spurious key press event is interpreted due to
incorrect array ranges. According to HID 1.11, section 6.2.2.5, arrays should
return a 0 value when no control is asserted, and ranges should go from 1 to
the number of elements. The patch clips the value with a logical range from
1..15 (instead of originally 0..18).
Ticket with more information available at
https://bugs.launchpad.net/bugs/326986
3. Descriptor size 135 bytes ("Gotview remote")
This receiver has a similar issue than the previous one, i.e. it mostly works
with regular HID input, except some key press events get stuck on key release.
The patch clips the array value from 1..14 (instead of originally 0..17).
Ticket with more information available at
http://bugs.archlinux.org/task/15216
4. Other unknown variants (found one report with 218 bytes,
but no further information about issues)
For such unknown variants we should refrain from changing any device flags.
Currently, HIDINPUT is suppressed and HIDDEV is enforced (because in 2.6.25 the
quirk table did not yet allow differentiating variants and we
did not expect variants either). Now we should be as strict as
possible and enable it only for the first variant above.

This off-by-one bug causes sendfile() to not work properly. When a task
calls sendfile() on a file on a CIFS filesystem, the syscall returns -1
and sets errno to EOVERFLOW.
do_sendfile uses s_maxbytes to verify the returned offset of the file.
The problem there is that this value is cast to a signed value (loff_t).
When this is done on the s_maxbytes value that cifs uses, it becomes
negative and the comparisons against it fail.
Even though s_maxbytes is an unsigned value, it seems that it's not OK
to set it in such a way that it'll end up negative when it's cast to a
signed value. These casts happen in other codepaths besides sendfile
too, but the VFS is a little hard to follow in this area and I can't
be sure if there are other bugs that this will fix.
It's not clear to me why s_maxbytes isn't just declared as loff_t in the
first place, but either way we still need to fix these values to make
sendfile work properly. This is also an opportunity to replace the magic
bit-shift values here with the standard #defines for this.
This fixes the reproducer program I have that does a sendfile and
will probably also fix the situation where apache is serving from a
CIFS share.

It was never actually doing anything anyway (see the loop condition),
and it would be difficult to make it work for RAID[56].
Even if it was actually working, it's checking for the wrong thing
anyway. Instead of checking whether we list a block which _doesn't_ land
at the relevant physical location, it should be checking that we _have_
listed all the logical blocks which refer to the required physical
location on all devices.
This function is only called from remove_sb_from_cache() to ensure that
we reserve the logical blocks which would reside at the same physical
location as the superblock copies. So listing more blocks than we need
is actually OK.
With RAID[56] we're going to throw away an entire stripe for each block
we have to ignore, so we _are_ going to list blocks other than the
ones which actually contain the superblock.

at91ether_probe lives in .init.text, so using platform_driver_register
to register it is wrong because binding a device after the init memory
is discarded (e.g. via sysfs) results in an oops.
As requested by David Brownell platform_driver_probe is used instead of
moving the probe function to .devinit.text as proposed initially.
This saves some memory, but devices registered after the driver is
probed are not bound (probably there are none) and binding via sysfs
isn't possible.
