Two years ago 5bbf89fc2608 removed the horrible bzImage unpacking code.
Now it's time to remove the unneeded zlib.h include, too.

New documentation for the adt7475 driver, based on the adt7473 driver
documentation. It is IMHO much more useful that the previous
documentation which was essentially redundant with sysfs-interface.

Add support for the ADT7473 to the adt7475 driver, and mark the
adt7473 driver for removal. The ADT7473 and ADT7475 chips are almost
the same chip and essentially compatible, so there's no point in
having separate drivers for them.

This adds support for the Fintek f71889fg to the f71882fg driver,
many thanks to Gerd v. Egidy for providing (remote) access to a
machine which such an ic.
Note that this bit of the patch:
- val = SENSORS_LIMIT(val, 0, 255);
+
+ if (data->type == f71889fg)
+ val = SENSORS_LIMIT(val, -128, 127);
+ else
+ val = SENSORS_LIMIT(val, 0, 127);
Changes behaviour for already supported models, the new behaviour is correct
as the already supported models have bit 7 of the involved registers fixed at
0, so the previous behaviour which allowed setting temp zone limits > 127
was not correct.

This module parameter is there to workaround broken BIOS. I'm not even
sure if it was used in the past 5 years, and it gets in the way of
converting the driver to the MFD infrastructure. So tell the users how
they can do the same from user-space.

The VID input pins can alternatively be used as GPIOs. Make sure we
have at least 4 pins used for VID, otherwise don't bother reading and
exposing VID.

This interface is mainly intended (and implemented) for ACPI _PPC BIOS
frequency limitations, but other cpufreq drivers can also use it for
similar use-cases.
Why is this needed:
Currently it's not obvious why cpufreq got limited.
People see cpufreq/scaling_max_freq reduced, but this could have
happened by:
- any userspace prog writing to scaling_max_freq
- thermal limitations
- hardware (_PPC in ACPI case) limitiations
Therefore export bios_limit (in kHz) to:
- Point the user that it's the BIOS (broken or intended) which limits
frequency
- Export it as a sysfs interface for userspace progs.
While this was a rarely used feature on laptops, there will appear
more and more server implemenations providing "Green IT" features like
allowing the service processor to limit the frequency. People want
to know about HW/BIOS frequency limitations.
All ACPI P-state driven cpufreq drivers are covered with this patch:
- powernow-k8
- powernow-k7
- acpi-cpufreq
Tested with a patched DSDT which limits the first two cores (_PPC returns 1)
via _PPC, exposed by bios_limit:
# echo 2200000 >cpu2/cpufreq/scaling_max_freq
# cat cpu*/cpufreq/scaling_max_freq
2600000
2600000
2200000
2200000
# #scaling_max_freq shows general user/thermal/BIOS limitations
# cat cpu*/cpufreq/bios_limit
2600000
2600000
2800000
2800000
# #bios_limit only shows the HW/BIOS limitation

This is a complex interface and is already described in
Documentation/cpu-freq/, especially in the user-guide.txt file.
No need to copy/paste all that information. Let's just alert the reader
to the presence of the user-guide.

When a CPU is offlined on POWER currently, we call rtas_stop_self() and hand
the CPU back to the resource pool. This path is used for DLPAR which will
cause a change in the LPAR configuration which will be visible outside.
This patch changes the default state a CPU is put into when it is offlined.
On platforms which support ceding the processor to the hypervisor with
latency hint specifier value, during a cpu offline operation,
instead of calling rtas_stop_self(), we cede the vCPU to the hypervisor
while passing a latency hint specifier value. The Hypervisor can use this hint
to provide better energy savings. Also, during the offline
operation, the control of the vCPU remains with the LPAR as oppposed to
returning it to the resource pool.
The patch achieves this by creating an infrastructure to set the
preferred_offline_state() which can be either
- CPU_STATE_OFFLINE: which is the current behaviour of calling
rtas_stop_self()
- CPU_STATE_INACTIVE: which cedes the vCPU to the hypervisor with the latency
hint specifier.
The codepath which wants to perform a DLPAR operation can set the
preferred_offline_state() of a CPU to CPU_STATE_OFFLINE before invoking
cpu_down().
The patch also provides a boot-time command line argument to disable/enable
CPU_STATE_INACTIVE.
