This patch distributes the Local Oscillator calibration bursts over time,
so that calibration only happens when it's actually needed.
Currently we periodically perform a recalibration of the whole table.
The table is huge and this takes lots of time. Additionally only small bits
of the table are actually needed at a given time. So instead of maintaining
a huge table with all possible calibration values, we create dynamic calibration
settings that
a) We only calibrate when they are actually needed.
b) Are cached for some time until they expire.
So a recalibration might happen if we need a calibration setting that's not
cached, or if the active calibration setting expires.
Currently the expire timeout is set to 30 seconds. We may raise that in future.
This patch reduces overall memory consumption by nuking the
huge static calibration tables.
This patch has been tested on several 4306, 4311 and 4318 flavours.

The current code checks for the special signature that signifies
a revision 4 SPROM. Now that a rev. 8 SPROM with a 440-byte length
has been found that may not have any special code, this check could
be relaxed. With this patch, if the CRC is incorrect for a 256-byte
SPROM, the code will immediately check for a 440-byte SPROM. If there
is still a CRC error, the size is set to 440 bytes, which allows dumping
of most of any 512-byte SPROM if one is encountered.

The hw_key_idx inside the ieee80211_key_conf structure does
not provide all the information drivers might need to perform
hardware encryption.
This is in particular true for rt2x00 who needs to know the
key algorithm and whether it is a shared or pairwise key.
By passing the ieee80211_key_conf pointer it assures us that
drivers can make full use of all information that it should know
about a particular key.
Additionally this patch updates all drivers to grab the hw_key_idx from
the ieee80211_key_conf structure.

All variants of the 5714, 5715, and 5780 offer a feature called the
"Universal Management Port". This feature is implemented in firmware
and is largely transparent to the driver, except...
It turns out that the UMP firmware needs to know the current status
of the link. Because the firmware cannot touch the PHY registers while
the driver is in control of the device, it needs the driver to report
link status changes through an additional handshaking mechanism.
Without this handshake, it has been observed in the field that the UMP
firmware will not operate correctly.
This patch implements the new handshake with the UMP firmware. Since
the handshake uses the same mechanism ASF heartbeats use, code was
added to detect and wait for completion of a pending previous event.

The MI clock is not configured correctly on adapters with the CPMU
present. The tg3 driver has code which statically sets the MI clock to
be a fraction of the speed at which the core clock is running.
However, the CPMU can change the adapter's core clock frequency based
on operating conditions. Consequently, the MI will run slow when the
core's clock has been slowed down.
There is a new 500KHz constant frequency clock available on adapters
with a CPMU. This patch removes the static core clock scaling and
configures the MI clock to use this new 500KHz clock instead.
Running the MI clock at slower speeds will not directly result in data
corruption, but it does challenge the PHY read and write routine timeouts.

Minor cleanup to the "usbtest" driver, mostly to resolve a regression:
all the important diagnostics were at KERN_DEBUG, so that when the
"#define DEBUG" was removed from the top of that file it stopped
providing diagnostics. Fix by using KERN_ERROR. Also:
- Stop using the legacy dbg() calls
- Simplify the internal debug macros
- Correct some test descriptions:
* Test #10 subcase 7 should *always* stall
* Test #10 subcase 8 *may* stall
- Diagnostic about control queue test failures is more informative
- Fix some whitespace "bugs"
And add a warning about the rude interaction between usbfs ioctl()
and khubd during device disconnect ... don't unplug a device under
test, that will wedge.

The wodim says:
"close track/session scsi sendcmd: cmd timeout after 5.000 (480) s"
This happened because we ignored the supplied timeout and used 5s.
It's not completely correct to apply a timeout meant for the complete
command to any single URB, but we don't have many URBs per command, so
this is simple and works.

Add support for variable-length, extended, and vendor specific
CDBs to scsi-ml. It is now possible for initiators and ULD's
to issue these types of commands. LLDs need not change much.
All they need is to raise the .max_cmd_len to the longest command
they support (see iscsi patch).
- clean-up some code paths that did not expect commands to be
larger than 16, and change cmd_len members' type to short as
char is not enough.

- struct scsi_cmnd had a 16 bytes command buffer of its own.
This is an unnecessary duplication and copy of request's
cmd. It is probably left overs from the time that scsi_cmnd
could function without a request attached. So clean that up.
- Once above is done, few places, apart from scsi-ml, needed
adjustments due to changing the data type of scsi_cmnd->cmnd.
- Lots of drivers still use MAX_COMMAND_SIZE. So I have left
that #define but equate it to BLK_MAX_CDB. The way I see it
and is reflected in the patch below is.
MAX_COMMAND_SIZE - means: The longest fixed-length (*) SCSI CDB
as per the SCSI standard and is not related
to the implementation.
BLK_MAX_CDB. - The allocated space at the request level
- I have audit all ISA drivers and made sure none use ->cmnd in a DMA
Operation. Same audit was done by Andi Kleen.
(*)fixed-length here means commands that their size can be determined
by their opcode and the CDB does not carry a length specifier, (unlike
the VARIABLE_LENGTH_CMD(0x7f) command). This is actually not exactly
true and the SCSI standard also defines extended commands and
vendor specific commands that can be bigger than 16 bytes. The kernel
will support these using the same infrastructure used for VARLEN CDB's.
So in effect MAX_COMMAND_SIZE means the maximum size command
scsi-ml supports without specifying a cmd_len by ULD's

A recent proposed feature addition to the virtio block driver revealed
some flaws in the API: in particular, we assume that feature
negotiation is complete once a driver's probe function returns.
There is nothing in the API to require this, however, and even I
didn't notice when it was violated.
So instead, we require the driver to specify what features it supports
in a table, we can then move the feature negotiation into the virtio
core. The intersection of device and driver features are presented in
a new 'features' bitmap in the struct virtio_device.
Note that this highlights the difference between Linux unsigned-long
bitmaps where each unsigned long is in native endian, and a
straight-forward little-endian array of bytes.
Drivers can still remove feature bits in their probe routine if they
really have to.
API changes:
- dev->config->feature() no longer gets and acks a feature.
- drivers should advertise their features in the 'feature_table' field
- use virtio_has_feature() for extra sanity when checking feature bits

A recent proposed feature addition to the virtio block driver revealed
some flaws in the API, in particular how easy it is to break big
endian machines.
The virtio config space was originally chosen to be little-endian,
because we thought the config might be part of the PCI config space
for virtio_pci. It's actually a separate mmio region, so that
argument holds little water; as only x86 is currently using the virtio
mechanism, we can change this (but must do so now, before the
impending s390 merge).
API changes:
- __virtio_config_val() just becomes a striaght vdev->config_get() call.

So, we previously had a 'VIRTIO_NET_F_GSO' bit which meant that 'the
host can handle csum offload, and any TSO (v4&v6 incl ECN) or UFO
packets you might want to send. I thought this was good enough for
Linux, but it actually isn't, since we don't do UFO in software.
So, add separate feature bits for what the host can handle. Add
equivalent ones for the guest to say what it can handle, because LRO
is coming too (thanks Herbert!).

x86 is the only arch right now, which provides an optimized for
div_long_long_rem and it has the downside that one has to be very careful that
the divide doesn't overflow.
The API is a little akward, as the arguments for the unsigned divide are
signed. The signed version also doesn't handle a negative divisor and
produces worse code on 64bit archs.
There is little incentive to keep this API alive, so this converts the few
users to the new API.

Don't over-write hwif->host_flags in ide_init_port(), some host drivers
set IDE_HFLAG_MMIO or IDE_HFLAG_NO_IO_32BIT host flag early.

pcmcia: remove pccard_sysfs_interface warnings
devres: support addresses greater than an unsigned long via dev_ioremap

sysfs: Disallow truncation of files in sysfs
Make the PCMCIA core stop using class_interface to hide socket attribute
registration. This removes the associated section mismatch warnings, and
helps get to the point where that mechanism can finally be removed.
Simplify that attribute registration by using an attribute_group.
This is a net shrink in object size.

The switch of ioremap to default to uncached doesn't break this driver
but it does needlessly slow it down as BIOS space is cachable and this
driver is quite happy scanning cached ROM space.
