Add currX_alarm, currX_min_alarm, currX_max_alarm and currX_beep
attributes to the hwmon sysfs API.

currX_min_alarm and currX_max_alarm are already supported by the LTC4215
and LTC4245 drivers. currX_alarm is supported by the LTC4261 driver.

We have the following naming convention documented in
Documentation/hwmon/sysfs-interface for fault files:

in[0-*]_input_fault
fan[1-*]_input_fault
temp[1-*]_input_fault

Some drivers follow this convention (lm63, lm83, lm90, smsc47m192).
However some drivers omit the "input" part and create files named
fan1_fault (pc87427) or temp1_fault (dme1737). And the new "generic"
libsensors follows this second (non-standard) convention, so it fails
to report fault conditions for drivers which follow the standard.

We want a single naming scheme, and everyone seems to prefer the
shorter variant, so let's go for it.

Extend the sysfs interface of hardware monitoring chips, by adding
individual alarm and beep files. Contrary to the old aggregated "alarms"
and "beeps" files, individual files constitute a standard way to access
the status information, making it finally possible to implement a
chip-independant hardware monitoring chip access library (once all
drivers have been added this new interface, that is.)

If future drivers need more individual files, the interface will be
extended as needed at the same time these drivers are merged into the
kernel tree.

This is my f71805f hardware monitoring driver ported from lm_sensors
to Linux 2.6. This new driver differs from the other hardware monitoring
drivers in that it is implemented as a platform driver. This might not
be optimal yet (we would probably need a generic infrastructure and bus
type for Super-I/O logical devices) but it is certainly much better than
the i2c-isa solution.

Note that this driver requires lm_sensors CVS. I hope to get it
released as 2.10.0 soon.

Add PEC support to the lm90 driver. Only the ADM1032 chip supports it,
and in a rather tricky way, which is why this patch comes with
documentation reinforcements. At least, this demonstrates that the new
PEC support logic in i2c-core can properly deal with chips with partial
PEC support.

As enabling PEC causes a significant performance drop, it can be
disabled through a sysfs file (unsurprisingly named "pec").

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
