* Changed test in lm75 setup code to 'read/write returns < 0' instead of
(old) 'read/write returns 0xff'. Nowadays, we can see the difference
between an error and a 0xff result, after all.
* Introduced constants used by PIIX4 for transaction types. These are
*not* the same as those in smbus.h.
* Some small code optimalizations in piix4.o.

* PIIX4: better names in /proc files
* sensors.c: fixed bug which prevented registration of non-ISA clients
Status:
* lm75 inserts happily and interacts with the PIIX4 correctly
* lm75 readings are still wrong (all 0xff)
* lm75 insertion with ISA bus present causes oops

* /proc/bus/i2c printed garbage if more than one adapter was registered
* There was a double line in piix4.c in the delay function

* Cleanup bug (ioports were not deregistered)
* PIIX4 search (it seems that for function 3, we must seek for a slightly
different device, too).

It compiles now for 2.0 kernels; I hope it still compiles for 2.1 kernels :-)
Changes:
* The non-BIOS PCI interface was introduced in kernel 2.1.54, so I changed
all #ifdef statements to use that kernel as starting point
* I integrated everything in piix4.h into piix4.c; as no other module will
ever need to know about anything PIIX4-specific, we do not need a
separate header file (same went for lm78.c and lm75.c)
* In piix4_setup, both the 2.0 and 2.1 versions continue seeking for PCI
devices until they have found 'function 3' of the PIIX4. This is the
'function' we need for SMBus access.
* At some places in piix4_setup, even for 2.1 kernels the PCI BIOS code was
used. This was seemingly needed, probably because the wrong 'function'
was accessed. I have removed this; if there are troubles with the PIIX4 on
kernels newer than 2.1.53, we need to introduce it again.
* Renamed global things to start uniformly with piix4_
* Changed printk statements to start with piix4.o:
* Pasted in missing part of piix4_access
* No need to lock the adapter on access; this is already done by the
smbus_access function in smbus.c. I corrected a locking bug there too,
by the way.
* Added a few include files needed by 2.0 at least
* Replaced the call to schedule_timeout() in piix4_do_pause with the old
code; schedule_timeout seems to be defined nowhere?!? Phil, was this
your addition, and if so, what should it read?

lm_sensors2 project. It was *very* easy to copy-and-paste it in, so I'm
hoping that it won't include any new bugs. It builds and compiles, but
I wasn't able to test it (under 2.1.131) until we get some compatibility
problems solved. There is probably a little cleaning up to do yet, but
everything looks like it is happy. Test it under 2.0.x and let me know
what happens.

Everything now compiles cleanly (except for warnings in kernel header files)
against 2.1.122. As I do not run 2.1 kernels, loading them could not be
tested.

Nothing much here yet, except some code to create /proc/bus/i2c. Should work
for kernels 2.0 and 2.1 (please test).
Other notable things:
printk statements in all modules made to have to same 'look'.

Though it is called the LM78 driver, there is not too much LM78 specific
code in it; it can better be seen as an example code skeleton for other
drivers. Right now, it creats a file /proc/sensors-test, which contains
a list of busses it registered itself on. Stupid, but very useful for
testing purposes!
You need a 2.0 kernel for lm78.o to insert (or hack the /proc system
specific parts; see lm78.c of lm_sensors version 1 how to do this).
Other parts of lm_sensors-2 are not tested for 2.1 kernels either, but
I am certain it won't work in this case :-).
See the TODO list to get some idea what is left to do, choose something
and implement it. Or not :-). But please, send a note to the mailing
list when you start on something, to avoid duplicate work...
Other notable changes:
the smbus_access routines now use (the more logical) i2c_adapter
structure, instead of smbus_adapter.

* Modules now print their version number and date on insertion
* Some printk statements missed a \n
* 'make clean' now works, even if some .d (dependency) files contain garbage.
Note that *only* 'make clean' helps in that case; 'make clean all', for
example, will fail! There is really no nice way to solve that.

The real PIIX4 access code must still be written; perhaps somebody else could
do this? Most of it could be copied from the old piix4.c. But check carefully
what you are doing, as some things *have* changed (like the SMBUS_{BYTE,...}
variables!).
