b43: Rewrite LO calibration algorithm
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.

Make forced module loading optional
The kernel module loader used to be much too happy to allow loading of
modules for the wrong kernel version by default. For example, if you
had MODVERSIONS enabled, but tried to load a module with no version
info, it would happily load it and taint the kernel - whether it was
likely to actually work or not!
Generally, such forced module loading should be considered a really
really bad idea, so make it conditional on a new config option
(MODULE_FORCE_LOAD), and make it default to off.
If somebody really wants to force module loads, that's their problem,
but we should not encourage it. Especially as it happened to me by
mistake (ie regular unversioned Fedora modules getting loaded) causing
lots of strange behavior.

Newer Dell OptiPlex 745s hang before rebooting after 'sudo reboot'.
A patch for some versions of the OptiPlex was proposed here --
http://lkml.org/lkml/2007/6/5/59 -- and is included in 2.6.23 and
later kernels, according to
http://lxr.linux.no/linux+v2.6.23/arch/i386/kernel/reboot.c . However,
the DMI_BOARD_NAME ("0WF810") is too restrictive. Newer OptiPlex
machines have a DMI_BOARD_NAME of "0RF703". I therefore suggest
adding another clause to reboot.c, similar to the one in the original
patch, but matching a DMI_BOARD_NAME of "0RF703".
On further inspection, it seems that there are other DMI_BOARD_NAMEs
for this same machine. They seem to change from time to time, which
means that the current code is fragile. Moreover, using bios reboot
should not break non-SFF OptiPlex 745s, and so a reasonable fix is to
simply drop the match on DMI_BOARD_NAME.

Not all device types need a wildcard at the end of their module

As I2C devices have no IDs, i2c module aliases are simple, arbitrary
device names. For example:
This would cause trouble if one I2C chip name matches the beginning of
another I2C chip name and both chips are supported by different
drivers. For example, an i2c device named lm9042 would cause the lm90
driver to be loaded, while it doesn't support that device. This case
has yet to be seen in practice, but still, I'd like to fix it now. The
cleanest fix is to remove the trailing wildcard from i2c module aliases.

netns: Fix device renaming for sysfs
When a netdev is moved across namespaces with the
'dev_change_net_namespace' function, the 'device_rename' function is
used to fixup kobject and refresh the sysfs tree. The device_rename
function will call kobject_rename and this one will check if there is
an object with the same name and this is the case because we are
renaming the object with the same name.
The use of 'device_rename' seems for me wrong because we usually don't
rename it but just move it across namespaces. As we just want to do a
mini "netdev_[un]register", IMO the functions
'netdev_[un]register_kobject' should be used instead, like an usual
network device [un]registering.
This patch replace device_rename by netdev_unregister_kobject,
followed by netdev_register_kobject.
The netdev_register_kobject will call device_initialize and will raise
a warning indicating the device was already initialized. In order to
fix that, I split the device initialization into a separate function
and use it together with 'netdev_register_kobject' into
register_netdevice. So we can safely call 'netdev_register_kobject' in
'dev_change_net_namespace'.
This fix will allow to properly use the sysfs per namespace which is
coming from -mm tree.

bnx2: Update RV2P firmware for 5709.
The new RV2P firmware fixes 2 issues:
1. The jumbo rx buffer page size is now configurable and set to the
proper PAGE_SIZE. Before, it was assumed to be always 4K.
2. Driver sometimes would crash when receiving jumbo packets mixed
with firmware management packets. This was caused by the old
firmware DMA'ing to the wrong address.

bnx2: Fix remote PHY initial link state.
On some remote PHY blade systems, the driver receives no initial link
interrupt. As a result, the GMII/MII MAC mode does not get setup properly.
To fix this problem, we add an initial poll of the link state after chip
reset.
With this change, the setting of the initial carrier state in the init
code can be eliminated.

bridge: forwarding table information for >256 devices
The forwarding table binary interface (my bad choice), only exposes
the port number of the first 8 bits. The bridge code was limited to
256 ports at the time, but now the kernel supports up 1024 ports, so
the upper bits are lost when doing:
brctl showmacs
The fix is to squeeze the extra bits into small hole left in data
structure, to maintain binary compatiablity.
