send_sig_info() has been broken since 2.5.60.

The function can be invoked from a the time interrupt (timer_interrpt ->
do_timer -> update_process_times -> -> update_one_process -> (
do_process_times, do_it_prof, do_it_virt ) -> -> send_sig ->
send_sig_info) but it uses spin_unlock_irq instead of the correct
spin_unlock_irqrestore. 

This enables interrupts, and later scheduler_tick() locks runqueue
(without disabling interrupts).  And if we are unlucky, a new interrupt
comes at this point.  And if this interrupt tries to do wake_up() (like
RTC interrupt does), we will deadlock on runqueue lock :-(

The bug was introduced by signal-fixes-2.5.59-A4, which split the
original send_sig_info into two functions, and in one branch it started
using these unsafe spinlock variants (while the "group" variant uses
irqsave/restore correctly). 

Thanks to Jonathan Corbet for pointing this out.

Thanks to Mike Anderson for the idea for this.

Don't provide min/max for in8, which allowed one to scribble on
registers one should not be messing with. (My fault, oops.)

The setting of the temp high/low registers was off by one, not mine this
time.  While I was at it, I reordered a few other register accesses to
be base 0 instead of base 1.

The temp interface was slightly incorrect, degrees * 100 instead of
degrees * 1000, also fixed.

And lastly, when changing the fan count divisor, fix up the min setting
to still be roughly the same. (Previously the meaning of the value in
the register changed, but not the value itself, resulting in, undesired
surprises.)

Ok, after writing up something in the way of a perl script to make some
sense of the data for voltages, and finding that there is no sense to
make, I took a longer look at things.

The it87 driver in 2.5.x is doing some, down right /odd/ math on the
numbers for the in_input* readings, and the 2.4.x driver is doing
something quite different.

And while it might be possible to get sane numbers out of the 2.5.x
driver, people /expect/ to get the numbers that they were getting from
2.4.x.

So this patch puts things back to the simpler calculations done by the
2.4.x lm-sensors drivers, and my script confirms that the numbers come
out right.

This is against my last.

While the old code most definitely did /something/ to the register for
setting the fan div, the 'what' is a more interesting question.

To be honest I could not figure out what it was trying to do, because
the way it was inserting values disagreed with not only the data sheet,
but how it parsed the very same register.

This corrects the issue, and allows one to properly control the divisor
on all 3 fans, including the (much more limited) 3rd fan.

definition.

Add I2C classes for analog and digital cameras, and fix a typo.
