Commit 7c08c9ae ("efifb/imacfb
consolidation + hardware support") claimed to remove imacfb entirely and
merge its DMI table into the efifb driver.  So far so good, but the diff
actually ended up just generating an empty file instead of removing it.

[ Technical reason: the patch header looked like

Tejun's commit 7b595756 made sysfs
attribute->owner unnecessary.  But the field was left in the structure to
ease the merge.  It's been over a year since that change and it is now
time to start killing attribute->owner along with its users - one arch at
a time!

This patch is attempt #1 to get rid of attribute->owner only for
CONFIG_X86_64 or CONFIG_X86_32 .  We will deal with other arches later on
as and when possible - avr32 will be the next since that is something I
can test.  Compile (make allyesconfig / make allmodconfig / custom config)
and boot tested.

akpm: the idea is that we put the declaration of sttribute.owner inside
`#ifndef CONFIG_X86'.  But that proved to be too ambitious for now because
new usages kept on turning up in subsystem trees.

It's OK to request the value of *any* GPIO; most GPIOs are bidirectional,
so configuring them as outputs just enables an output driver and doesn't
disable the input logic.

So the problem is that gpio_get_value_cansleep() isn't making the same
sanity check that gpio_get_value() does: making sure this GPIO isn't one
of the atypical "no input logic" cases.

Teach rtc-cmos about the second bank of registers found on most modern x86
systems, giving access to 128 bytes more NVRAM.

This version only sees that extra NVRAM when both register banks are
provided as part of *one* PNP resource.  Since BIOS on some systems
presents them using two IO resources, and nothing merges them, this can't
always show all the NVRAM.  (We're supposed to be able to use PNP id
PNP0b01 too, but BIOS tables doesn't often seem to use that particular
option.)

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

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.

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:

- CHAN_ALM_* constants for (later) vin, temp alarm callbacks.
- CHAN_* conversion constants, used in _init_device, partly for RW1C bits
