Added probe_only module option to hd-audio driver.
This option specifies whether the driver creates and initializes the
codec-parser after probing. When this option is set, the driver skips
the codec parsing and initialization but gives you proc and other
accesses. It's useful to see the initial codec state for debugging.
The default of this value is off, so the default behavior is as same
as before.

The current auto-configuration code has several problems especially
for the new IDT codecs, e.g. wrong assignment of pins and DACs or
coupled volume for speaker and headphone.
This patch is a fairly large rewrite of the auto-configuration code.
Some remaks
- mic_switch and line_switch contain NIDs instead of bool
- dac_list isn't fixed for IDT 92HD* codecs now, they are all probed
- extra HP and speakers are stored in extra_dacs[].

The previous commit re-enabled hp_nid setup for IDT92HD73*, but
it's unneeded indeed for Dell laptops that have multiple headphones.
Setting the extra hp_nid results in a non-working "Headpohne" mixer
control. Thus hp_nid should be 0 for these dell models.
Also, the automatic addition of hp_nid should check whether it's
a dual-HP model or not. For dual-HPs, the pins are already checked
by the early workaround.

In the presence of extended topology eumeration leaf 0xb provided

then delete the first array, and it will blow up in deregister_disk(), in

The timeout handling code is currently broken in several ways:
- It calls stop() (which frees all the memory and IRQ), and then
calls startup() (which won't re-request IRQ, neither it will
re-init the Fast UCC structure).
- It calls these routines from the softirq context, which is wrong,
since stop() calls free_irq() (which might sleep) and startup()
allocates things with GFP_KERNEL.
- It won't soft-reset the PHY. We need the PHY reset for at least
MPC8360E-MDS boards with Marvell 88E1111 PHY, the PHY won't recover
from timeouts w/o the reset.
So the patch fixes these problems by implementing the workqueue for the
timeout handling, and there we fully re-open the device via close() and
open() calls. The close/open paths do the right things, and I can see
that the driver actually survive the timeouts.

Currently the routines wait for the various bits w/o an assumption that
bits may never get set. When timeouts happen I see that these bits never
get set and so the routines hang the kernel.
With this patch we'll wait the graceful stop for 100 ms, and then will
simply exit. There is nothing* we can do about that, but it's OK since
we'll do full reset later.
* Well, actually, there is also not-graceful variant for the TX stop,
but specs says that we never should use it.

Implementing discard counters for the NIU driver turned out to be more
complicated than first assumed.
The discard counters for the NIU neptune chip are only 16-bit (even
though this is a 64-bit chip). These 16-bit counters can overflow
quickly, especially considering this is a 10Gbit/s ethernet card.
The overflow indication bit is, unfortunatly, not usable as the
counter value does not wrap, but remains at max value 0xFFFF.
Resulting in lost counts until the counter is reset.
The read and reset scheme also poses a problem. Both in theory and in
practice counters can be lost in between reading nr64() and clearing
the counter nw64(). For this reason, the number of counter clearings
nw64() is limited/reduced. On the fast-path the counters are only
syncronized once it exceeds 0x7FFF. When read by userspace, its
syncronized fully.

A major source of overhead in the enc28j60 driver is the SPI transfers. Each
SPI transfer entails two kernel thread context switches. One major source of
SPI transfers is the enc28j60_set_bank() functions which runs before every
register access. This patch reduces the number of SPI transfers that
enc28j60_set_bank() performs in two ways:
1. removes unnecessary bank switch for the registers that are present in all
banks
2. when switching from banks 0 or 3 to banks 1 or 2 (i.e. only one bit
changes) enc28j60_set_bank() does only one SPI transfer instead of two
According to my tests these changes reduce the number of SPI transfers in
about 25%.

| netdevice zd1201: Convert directly reference of netdev->priv to netdev_priv()
|
| We have some reasons to kill netdev->priv:
| 1. netdev->priv is equal to netdev_priv().
| 2. netdev_priv() wraps the calculation of netdev->priv's offset, obviously
| netdev_priv() is more flexible than netdev->priv.
| But we cann't kill netdev->priv, because so many drivers reference to it
| directly.
|
| OK, becasue Dave S. Miller said, "every direct netdev->priv usage is a bug",
| and I want to kill netdev->priv later, I decided to convert all the direct
| reference of netdev->priv first.
|
| (Original patch posted by Wang Chen <wangchen@cn.fujitsu.com> w/ above
| changelog but using dev->ml_priv. That doesn't seem appropriate
| to me for this driver, so I've revamped it to use netdev_priv()
| instead. -- JWL)

When we read the write-intent-bitmap off the device, we currently
read a whole number of pages.
When PAGE_SIZE is 4K, this works due to the alignment we enforce
on the superblock and bitmap.
When PAGE_SIZE is 64K, this case read past the end-of-device
which causes an error.
When we write the superblock, we ensure to clip the last page
to just be the required size. Copy that code into the read path
to just read the required number of sectors.
