On some recent Macbooks, the package length for the light sensors ALV0 and
ALV1 has changed from 6 to 10. This patch allows for a variable package
length encompassing both variants.

The time to wait for a status change while reading or writing to the SMC
ports is a balance between read reliability and system performance. The
current setting yields rougly three errors in a thousand when
simultaneously reading three different temperature values on a Macbook
Air. This patch increases the setting to a value yielding roughly one
error in ten thousand, with no noticable system performance degradation.

On many Macbooks since mid 2007, the Pro, C2D and Air models, applesmc
fails to read some or all SMC ports. This problem has various effects,
such as flooded logfiles, malfunctioning temperature sensors,
accelerometers failing to initialize, and difficulties getting backlight
functionality to work properly.
The root of the problem seems to be the command protocol. The current
code sends out a command byte, then repeatedly polls for an ack before
continuing to send or recieve data. From experiments leading to this
patch, it seems the command protocol never quite worked or changed so that
one now sends a command byte, waits a little bit, polls for an ack, and if
it fails, repeats the whole thing by sending the command byte again.
This patch implements a send_command function according to the new
interpretation of the protocol, and should work also for earlier models.

Adds therm-min/max/crit-alarm callbacks, sensor-device-attribute
declarations, and refs to those new decls in the macro used to initialize
the therm_group (of sysfs files)
The thermistors use voltage channels to measure; so they don't have a
fault-alarm, but unlike the other voltages, they do have an overtemp,
which we call crit (by convention).

Bring hwmon/pc87360 into agreement with
Documentation/hwmon/sysfs-interface.
Patchset adds separate limit alarms for voltages and temps, it also adds
temp[123]_fault files. On my Soekris, temps 1,2 are unused/unconnected,
so temp[123]_fault = 1,1,0 respectively. This agrees with
/usr/bin/sensors, which has always shown them as OPEN. Temps 4,5,6 are
thermistor based, and dont have a fault bit in their status register.
This patch:
2 different kinds of constants added:
- CHAN_ALM_* constants for (later) vin, temp alarm callbacks.
- CHAN_* conversion constants, used in _init_device, partly for RW1C bits

Split the LRU lists in two, one set for pages that are backed by real file
systems ("file") and one for pages that are backed by memory and swap
("anon"). The latter includes tmpfs.
The advantage of doing this is that the VM will not have to scan over lots
of anonymous pages (which we generally do not want to swap out), just to
find the page cache pages that it should evict.
This patch has the infrastructure and a basic policy to balance how much
we scan the anon lists and how much we scan the file lists. The big
policy changes are in separate patches.
