hwmon: (applesmc) Always read until end of data
The crash reported and investigated in commit 5f4513 turned out to be
caused by a change to the read interface on newer (2012) SMCs.
Tests by Chris show that simply reading the data valid line is enough
for the problem to go away. Additional tests show that the newer SMCs
no longer wait for the number of requested bytes, but start sending
data right away. Apparently the number of bytes to read is no longer
specified as before, but instead found out by reading until end of
data. Failure to read until end of data confuses the state machine,
which eventually causes the crash.
As a remedy, assuming bit0 is the read valid line, make sure there is
nothing more to read before leaving the read function.
Tested to resolve the original problem, and runtested on MBA3,1,
MBP4,1, MBP8,2, MBP10,1, MBP10,2. The patch seems to have no effect on
machines before 2012.

hwmon: (applesmc) Decode and act on read/write status codes
The behavior of the SMC has changed several times over the years,
causing read failures in the driver. It seems the problem can be
explained by a shift in SMC speed combined with improper action on
status codes.
We should first wait for the SMC to settle, which was the most
frequent response on the old slow machines. Then, if the SMC is busy,
we need to try again later by resending the command. This was the most
likely response until 2012. Now, with a shorter wait time, we are
again most likely to poll while the SMC is settling, and as a result
we see high failure rates on many old and new models.
With the distinction between busy and failure, we can also wait longer
before retrying, without sacrificing speed. This seems to bring
failures down to virtually zero on all models.

hwmon: (applesmc) Allow negative temperature values
There are many userland reports of sensors with unreasonably small and
large temperatures. There seem to be several reasons for this:
Firstly, the major sensor type (sp78) is actually a signed number.
This explains why some sensors show very small or large values - they
are in fact all small, but of different sign.
Secondly, the other sensor type (1-hex) is not properly understood; it
may be that it is not a temperature after all.
Thirdly, some sensors are differential in nature, showing changes over
time rather than absolute numbers. This explains why those values are
small and of varying sign.
This patch interprets the sp78 type as signed short, but keeps the
original scaling. For other types, -EINVAL is returned, since the
nature of those sensors is unknown.

hwmon: (applesmc) Shorten minimum wait time
The 2012 series of MacBooks have a faster SMC, and the current driver
timings do not work at all. Tests show that decreasing the minimum
wait time, from 64 us to 16 us, works well. Since this is still larger
than the original minimum of 10 us used before 2008, there is nothing
inherently problematic with changing it. The fail frequency on older
machines seems to increase slightly, but not enough to be noticeable.
Tested on MBA11, MBA31, MBA5,2, MBP9,2.

hwmon: applesmc: fix light sensor readings on newer MacBooks
The light sensors ALV0 and ALV1 on newer MacBooks (early 2008 and later)
changed to report 10 bytes instead the earlier 6, and the sensor encoding
subsequently changed. As a result, the reported light sensors readings
are much too low.
Via experiments leading up to this patch, it seems only the ALV0 is
reporting data, and the most useful value therein is a 10-bit big-endian
value at offset 6. This suggests that a new protocol was added as a
backward-compatible replacement on top of the old one.
This patch makes applesmc report the improved light sensor reading for the
new machines, on a scale in conformance with earlier ones.

hwmon: applesmc: lighter wait mechanism, drastic improvement
The read fail ratio is sensitive to the delay between the first byte
written and the first byte read; apparently the sensors cannot be rushed.
Increasing the minimum wait time, without changing the total wait time,
improves the fail ratio from a 8% chance that any of the sensors fails in
one read, down to 0.4%, on a Macbook Air. On a Macbook Pro 3,1, the
effect is even more apparent. By reducing the number of status polls, the
ratio is further improved to below 0.1%. Finally, increasing the total
wait time brings the fail ratio down to virtually zero.

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.

hwmon: applesmc: fix the 'wait status failed: c != 8' problem
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.

hwmon: (applesmc) Add support for Mac Pro 2 x Quad-Core
At least the 2x Quad-Core Apple Mac Pro appears to have some over-heat
protection which suddenly powers off the whole box under load. This adds
support for the fans and temerature sensors in the Mac Pro - later some
"windwarm" a-like code should probably monitor the values. For now
manually tweaking the fans prevents the sudden shutdown for me.
cd /sys/devices/platform/applesmc.768
for x in fan{1,2,3,4}; do
echo 1 > ${x}_manual
echo 1285 > ${x}_output
done
Two sensors are 0, while four are 129 °C, those might be removed again,
later.

drivers/firmware: const-ify DMI API and internals
Three main sets of changes:
1) dmi_get_system_info() return value should have been marked const,
since callers should not be changing that data.
2) const-ify DMI internals, since DMI firmware tables should,
whenever possible, be marked const to ensure we never ever write to
that data area.
3) const-ify DMI API, to enable marking tables const where possible
in low-level drivers.
And if we're really lucky, this might enable some additional
optimizations on the part of the compiler.
The bulk of the changes are #2 and #3, which are interrelated. #1 could
have been a separate patch, but it was so small compared to the others,
it was easier to roll it into this changeset.
