This patch also registers all necessary callbacks to support mute LED

Since the addition of file capabilities every write needs to read xattrs to
check if we have any capabilities to clear. In Linux 3.0 Andi Kleen added
a flag to cache the fact that we do not have any attributes on an inode.
Make sure to already mark a file as not having any attributes when reading
it from disk in case it doesn't even have an attribute fork. Based on an
earlier patch from Andi Kleen.

We need to take some locks to prevent new ioends from coming in when we wait
for all existing ones to go away. Up to Linux 3.0 that was done using the
i_mutex held by the VFS fsync code, but now that we are called without
it we need to take care of it ourselves. Use the I/O lock instead of
i_mutex just like we do in other places.

Now that REQ_META bios aren't treated specially in the CFQ I/O schedule
anymore, we can tag all buffers as metadata to make blktrace traces more
meaningful. Note that we use buffers also to zero out partial blocks
in the preallocation / hole punching code, and while they operate on
data blocks the zeros written certainly aren't data. I think this case
is borderline metadata enough to not bother special casing it.

This patch simplifies journal handling in setup_new_group_blocks().
In previous code, block bitmap is modified everywhere in
setup_new_group_blocks(), ext4_get_write_access() in
extend_or_restart_transaction() is used to guarantee that the block
bitmap stays in the new handle, this makes things complicated.
The previous commit changed things so that the modifications on the
block bitmap are batched and done by ext4_set_bits() at the end of the
for loop. This allows us to simplify things.

Before this patch, parallel resizers are allowed and protected by a
mutex lock, actually, there is no need to support parallel resizer, so
this patch prevents parallel resizers by atmoic bit ops, like
lock_page() and unlock_page() do.
To do this, the patch removed the mutex lock s_resize_lock from struct
ext4_sb_info and added a unsigned long field named s_resize_flags
which inidicates if there is a resizer.

It might be not good to use software defined version to identify sdma
device type, when hardware does not define such version. Instead,
soc name is stable enough to define the device type.
The patch uses platform_device_id rather than version number passed
by platform data to identify sdma device type/version.

Neither platform based nor dt based device needs to pass the parent
to sdhci_alloc_host. There is no difference between platform and dt
on this point.
The patch makes the change to pass device itself than its parent to
sdhci_alloc_host for dt case too. Otherwise the probe function of
sdhci based drivers which is shared between platform and dt will
fail on dt case.

family and more scenarios supported. The changes include:
* Turn platform_data from optional to mandatory
* Add cd_types and wp_types into platform_data to cover more use
cases
* Remove the use of flag ESDHC_FLAG_GPIO_FOR_CD
* Adjust some machine codes to adopt the platform_data changes
* Work around the issue that software reset will get card detection
circuit stop working

On the recent i.mx (mx25/50/53), there is a gasket inside fec
controller which needs to be enabled no matter phy works in MII
or RMII mode.
The current code enables the gasket only when phy interface is RMII.
It's broken when the driver works with a MII phy. The patch uses
platform_device_id to distinguish the SoCs that have the gasket and
enables it on these SoCs for both MII and RMII mode.

The patch removes all the uses of cpu_is_mx1(). Instead, it uses
the .id_table of platform_driver to distinguish the uart device type,
IMX1_UART and IMX21_UART. The IMX21_UART type runs on all i.mx
except i.mx1.
A couple of !cpu_is_mx1 logic gets turned into is_imx21_uart,
as the codes wrapped there are really IMX21 type uart specific.
It also removes macro MX1_UCR3_REF25 and MX1_UCR3_REF30 which are
not used anywhere.

While preparing to write a stripe we keep the parity block or blocks
locked (R5_LOCKED) - towards the end of schedule_reconstruction.
If the array is discovered to have failed before this write completes
we can leave those blocks LOCKED, and init_stripe will notice that a
free stripe still has a locked block and will complain.
So clear the R5_LOCKED flag in handle_failed_stripe, and demote the
'BUG' to a 'WARN_ON'.

Normally we would fail a device with a READ error. However if doing
so causes the array to fail, it is better to leave the device
in place and just return the read error to the caller.
The current test for decide if the array will fail is overly
simplistic.
We have a function 'enough' which can tell if the array is failed or
not, so use it to guide the decision.

When we get a read error during recovery, RAID10 previously
arranged for the recovering device to appear to fail so that
the recovery stops and doesn't restart. This is misleading and wrong.
Instead, make use of the new recovery_disabled handling and mark
the target device and having recovery disabled.
Add appropriate checks in add_disk and remove_disk so that devices
are removed and not re-added when recovery is disabled.

If we hit a read error while recovering a mirror, we want to abort the
recovery without necessarily failing the disk - as having a disk this
a read error is better than not having an array at all.
Currently this is managed with a per-array flag "recovery_disabled"
and is only implemented for RAID1. For RAID10 we will need finer
grained control as we might want to disable recovery for individual
devices separately.
So push more of the decision making into the personality.
'recovery_disabled' is now a 'cookie' which is copied when the
personality want to disable recovery and is changed when a device is
added to the array as this is used as a trigger to 'try recovery
again'.
This will allow RAID10 to get the control that it needs.
