Add compat option to hid code to allow loading of all modules on
systems which don't allow autoloading because of old userspace.

Move ignore quirks from usbhid-quirks into hid-core code. Also don't output
warning when ENODEV is error code in usbhid and try ordinal input in hidp
when that error is returned.

Next step for complete hid bus, this patch includes:
- call parser either from probe or from hid-core if there is no probe.
- add ll_driver structure and centralize some stuff there (open, close...)
- split and merge usb_hid_configure and hid_probe into several functions
to allow hooks/fixes between them

Make a bus from hid core. This is the first step for converting all the
quirks and separate almost-drivers into real drivers attached to this bus.
It's implemented to change behaviour in very tiny manner, so that no driver
needs to be changed this time.
Also add generic drivers for both usb and bt into usbhid or hidp
respectively which will bind all non-blacklisted device. Those blacklisted
will be either grabbed by special drivers or by nobody if they are broken at
the very rude base.

nf_nat
This patch removes the module dependency between ctnetlink and
nf_nat by means of an indirect call that is initialized when
nf_nat is loaded. Now, nf_conntrack_netlink only requires
nf_conntrack and nfnetlink.
This patch puts nfnetlink_parse_nat_setup_hook into the
nf_conntrack_core to avoid dependencies between ctnetlink,
nf_conntrack_ipv4 and nf_conntrack_ipv6.
This patch also introduces the function ctnetlink_change_nat
that is only invoked from the creation path. Actually, the
nat handling cannot be invoked from the update path since
this is not allowed. By introducing this function, we remove
the useless nat handling in the update path and we avoid
deadlock-prone code.
This patch also adds the required EAGAIN logic for nfnetlink.

we're at it.

The WM8350 has an interrupt line to the CPU which is shared by the
devices on the CPU. This patch adds support for the interrupt
controller within the WM8350 which identifies which identifies the
interrupt cause. In common with other similar chips this is done
outside the standard interrupt framework due to the need to access
the interrupt controller over an interrupt-driven bus.

The WM8350 provides a number of user-configurable pins providing access
to various signals generated by the functions on the chip. These are
referred to as GPIO pins in the device documentation but in Linux terms
they are more general than that, providing configuration of alternate
functions.
This patch implements support for selecting the alternate functions for
these pins. They can also be used as GPIOs in the normal Linux sense -
a subsequent patch will add support for doing so.

The WM8350 is an integrated audio and power management subsystem
intended for use as the primary PMIC in mobile multimedia applications.
The WM8350 can be controlled via either I2C or SPI - the control
interface is provided by a separate module in order to allow greatest
flexibility in configuring the kernel.
This driver was originally written by Liam Girdwood and has since been
updated to current kernel APIs and split up for submission by me. All
the heavy lifting here was done by Liam.

This improves the machine level API in order to configure
regulator constraints and consumers as platform data and removes the
old string based API that required several calls to set up each regulator.
The intention is to create a struct regulator_init_data, populate
it's fields with constraints, consumers devices, etc and then register
the regulator device from board.c in the standard Linux way.
e.g. regulator LDO2 (supplying codec and sim) platform data.
/* regulator LDO2 consumer devices */
static struct regulator_consumer_supply ldo2_consumers[] = {
{
.dev = &platform_audio_device.dev,
.supply = "codec_avdd",
},
{
.dev = &platform_sim_device.dev,
.supply = "sim_vcc",
}
};
/* regulator LDO2 constraints */
static struct regulator_init_data ldo2_data = {
.constraints = {
.min_uV = 3300000,
.max_uV = 3300000,
.valid_modes_mask = REGULATOR_MODE_NORMAL,
.apply_uV = 1,
},
.num_consumer_supplies = ARRAY_SIZE(ldo2_consumers),
.consumer_supplies = ldo2_consumers,
};
/* machine regulator devices with thier consumers and constraints */
static struct platform_device wm8350_regulator_devices[] = {
{
.name = "wm8350-regulator",
.id = WM8350_LDO_2,
.dev = {
.platform_data = &ldo2_data,
},
},
};
Changes in detail:-
o Removed all const char* regulator config functions in machine API.
o Created new struct regulator_init_data to contain regulator
machine configuration constraints and consmuers.
o Changed set_supply(), set_machine_constraints(),
set_consumer_device_supply() to remove their string identifier
parameters. Also made them static and moved functions nearer top of
core.c.
o Removed no longer used inline func to_rdev()
o Added regulator_get_init_drvdata() to retrieve init data.
o Added struct device* as parameter to regulator_register().
o Changed my email address.

On user request (through sysfs), the IDLE IMMEDIATE command with UNLOAD
FEATURE as specified in ATA-7 is issued to the device and processing of
the request queue is stopped thereafter until the specified timeout
expires or user space asks to resume normal operation. This is supposed
to prevent the heads of a hard drive from accidentally crashing onto the
platter when a heavy shock is anticipated (like a falling laptop expected
to hit the floor). Port resets are deferred whenever a device on that
port is in the parked state.

v4:
Fix a memory leak due to a missing blk_put_request() in
issue_park_cmd(). Additionally, we should plug the queue when enqueueing
the unpark request because there is no guarantee that the park timeout
has not expired by then. Even though the chance for that to happen is
very slim, the request might end up hanging in the queue until the next
I/O operation is queued up. While at it, clean up the code a little:
- make issue_park_cmd() a function of type void since nobody cares for
the return value anyway;
- use blk_start_queueing() instead of __blk_run_queue() since we don't
have to worry about recursion;
- remove a superfluous pointer deference in task_no_data_intr().

Follow-up to commit 5c05ff68b9a9b40a9be949497e0aa980185565cf
("ide: switch to DMA-mapping API"):
* pci_{alloc,free}_consistent() -> dma_{alloc,free}_coherent()
in ide_{allocate,release}_dma_engine().
* Add ->prd_max_nents and ->prd_ent_size fields to ide_hwif_t
(+ set default values in ide_allocate_dma_engine()).
* Make ide_{allocate,release}_dma_engine() available also
for CONFIG_BLK_DEV_IDEDMA_SFF=n. Then convert au1xxx-ide.c,
scc_pata.c and sgiioc4.c to use them.
* Add missing ->init_dma method to scc_pata.
This patch also fixes:
- ->dmatable_cpu leak for au1xxx-ide
- too early realease of ->dmatable_cpu for scc_pata
- wrong amount of ->dmatable_cpu memory being freed for sgiioc4
While at it:
- remove superfluous ->dma_base check from ide_unregister()
- return -ENOMEM on error in ide_release_dma_engine()
- beautify error message in ide_release_dma_engine()

Make ide_dma_timeout() available also for CONFIG_BLK_DEV_IDEDMA_SFF=n
and convert {ics,au1xxx-}ide.c to use it.
While at it:
- dump ATA Status register content on error
- use EXPORT_SYMBOL_GPL() to match the rest of SFF DMA functions
