Yet another architecture not coverd by GEN_RTC - sparc64 never picked
it until now and it doesn't have asm/rtc.h to go with it, so it
wouldn't compile anyway (or have these ioctls in the user-visible
headers, for that matter).
FWIW, I'm very tempted to introduce ARCH_HAS_GEN_RTC and have it set
in arch/*/Kconfig for architectures that know what to do with this
stuff - for something supposedly generic the list of architectures
where it doesn't work is getting too long...

Use the status tag to determine if there are new events in
tg3_interrupt_tagged(). We discussed about this a while ago with Grant
Grundler and DaveM. This scheme makes it unnecessary to clear the
updated bit in the status block when using tagged mode, and only
a simple comparison is needed to determine if there are new events.
The tp->lock around netif_rx_complete() and tg3_restart_ints() is also
removed. It is unnecessary with DaveM's new locking scheme.

Remove unnecessary status block accesses in tg3_msi(). Since MSI is
not shared, it is unnecessary to read the status block to determine if
there are any new events in the MSI handler. It is also unnecessary to
clear the updated bit in the status block.
Since the poll list is per-cpu, tg3_poll() will be scheduled to run on
the same CPU that received the MSI. Prefetches for the status block
and the next rx descriptors are added in tg3_msi() to improve their
access times when tg3_poll() runs.
In the non-MSI irq handlers, we need to check the status block because
interrupts may be shared. Only prefetches for the next rx descriptors
are added.

pc87360: number-skew to init
The temp, therm, fan, pwm callbacks all have an offset skew in the code
which accommodates attribute numbering conventions under
/sys/bus/i2c/devices/9191-6620/ (ie they start at 1)
This patch moves that skew into the declaration, and out of the
functions (except for therm, where we simplify from 2 skews to 1). The
declarative skew is clearer, less error-prone, and more efficient.
The use of 11+offset-4 below reflects the fact that the sysfs numbering
of these units is 4, 5, 6, but they use internal VLM units 11, 12, 13 to
measure the thermistor voltages.
There's one remaining skew factor, in *_crit callbacks below, because
there are no critical thresholds for voltages 0-10, only for those
supporting the thermistors.

The i2c-keywest driver has a "probe" module parameter which enables bus
scanning at load time. This can be done in userspace with the i2cdetect
tool (part of the lm_sensors package) instead. What's more, i2cdetect
gives more control on the way the bus is scanned, and is safer
(i2c-keywest currently scans reserved addresses and doesn't properly
handle the famous 24RF08 corruption case.)
Thus, I would propose that this module parameter be simply dropped.

I2C_DEVNAME and i2c_clientname were introduced in 2.5.68 [1] to help
media/video driver authors who wanted their code to be compatible with
both Linux 2.4 and 2.6. The cause of the incompatibility has gone since
[2], so I think we can get rid of them, as they tend to make the code
harder to read and longer to preprocess/compile for no more benefit.
I'd hope nobody seriously attempts to keep media/video driver compatible
across Linux trees anymore, BTW.

In theory, there should be no more users of I2C_ALGO_* at this point.
However, it happens that several drivers were using I2C_ALGO_* for
adapter ids, so we need to correct these before we can get rid of all
the I2C_ALGO_* definitions.
Note that this also fixes a bug in media/video/tvaudio.c:
/* don't attach on saa7146 based cards,
because dedicated drivers are used */
if ((adap->id & I2C_ALGO_SAA7146))
return 0;
This test was plain broken, as it would succeed for many more adapters
than just the saa7146: any those id would share at least one bit with
the saa7146 id. We are really lucky that the few other adapters we want
this driver to work with did not fulfill that condition.

The 24RF08 corruption would better be prevented at i2c-core level than
at chip driver level, for several reasons:
* The second quick write should happen as soon as possible after the
first one, so as to limit the risk that another command is issued on
the bus inbetween, causing the corruption.
* As a matter of fact, the protection code at driver level was reworked
at least three times already, which proves how hard it is to get it
right there, while it's straightforward at i2c-core level.
* It's easy to add a new driver that would need the protection, and
forget to add it. This did happen already.
* As additional probing addresses can be passed to most i2c chip drivers
as module parameters, virtually every i2c chip driver would need the
protection if we want to be really safe.
* Why duplicate code when we can easily avoid it?

i2c_probe was quite complex and slow, so I rewrote it in a more
efficient and hopefully clearer way.
Note that this slightly changes the way the module parameters are
handled. This shouldn't change anything for the most common cases
though.
For one thing, the function now respects the order of the parameters
for address probing. It used to always do lower addresses first. The
new approach gives the user more control.
For another, ignore addresses don't overrule probe addresses anymore.
This could have been restored the way it was at the cost of a few more
lines of code, but I don't think it's worth it. Both lists are given
as module parameters, so a user would be quite silly to specify the
same addresses in both lists. The normal addresses list is the only
one that isn't controlled by a module parameter, thus is the only one
the user may reasonably want to remove an address from.
Another significant change is the fact that i2c_probe() will no more
stop when a detection function returns -ENODEV. Just because a driver
found a chip it doesn't support isn't a valid reason to stop all
probings for this one driver. This closes the long standing lm_sensors
ticket #1807.
http://www2.lm-sensors.nu/~lm78/readticket.cgi?ticket=1807
I updated the documentation accordingly.
In terms of algorithmic complexity, the new code is way better. If
I is the ignore address count, P the probe address count, N the
normal address count and F the force address count, the old code
was doing 128 * (F + I + P + N) iterations max, while the new code
does F + P + ((I+1) * N) iterations max. For the most common case
where F, I and P are empty, this is down from 128 * N to N.
