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.)

I2C_DEVNAME and i2c_clientname were introduced in 2.5.68 [1] to help

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.

Common i/o layer changes:
- Collect the irb at the correct subchannel when waiting for the clear
interrupt during subchannel cleaning befor reIPL - don't stop at the first
interrupt that comes in.
- Change "extern __inline__" to "static inline".
- Remove unneeded qdio includes.

Reintroduce a read-only copy of the devmap features in the device struct.
This is necessary to solve a deadlock on the dasd_devmap_lock which is
acquired by dasd_get_features called from the dasd tasklet. The current
implementation of devmap doesn't allow to call any devmap function from
interrupt or softirq context.

The new machine check handler still has a few bugs.
1) The system entry time has to be stored in the machine check handler,
2) the machine check return psw may not be stored at the usual place
because it might overwrite the return psw of the interrupted context,
3) the return address for the call to s390_handle_mcck in the i/o interrupt
handler is not correct,
4) the system call cleanup has to take the different save area of the
machine check handler into account,
5) the machine check handler may not call UPDATE_VTIME before
CREATE_STACK_FRAME, and
6) the io leave path needs a critical section cleanup to make sure that the
TIF_MCCK_PENDING bit is really checked before switching back to user space.

This adds type-checking to pm_message_t, so that people can't confuse it
with int or u32. It also allows us to fix "disk yoyo" during suspend (disk
spinning down/up/down).
[We've tried that before; since that cpufreq problems were fixed and I've
tried make allyes config and fixed resulting damage.]

PowerPC 40x and Book-E processors support a watchdog timer at the processor
core level. The timer has implementation dependent timeout frequencies
that can be configured by software.
One the first Watchdog timeout we get a critical exception. It is left to
board specific code to determine what should happen at this point. If
nothing is done and another timeout period expires the processor may
attempt to reset the machine.
Command line parameters:
wdt=0 : disable watchdog (default)
wdt=1 : enable watchdog
wdt_period=N : N sets the value of the Watchdog Timer Period.
The Watchdog Timer Period meaning is implementation specific. Check
User Manual for the processor for more details.
This patch is based off of work done by Takeharu Kato.
