The RPM after conversion from / before conversion to a register value can be
much more than 65535 (up to 1500000), so putting this into an u16 can cause
overflows. This changes the functions to use an int to store / get RPM instead.

While studying the datasheets for adding F8000 support, I noticed that the
F718x2 has separate alarms (and beep control) for its max and crit limits.
We keep the temp#_alarm attributes as they are, even though it would be more
logical to rename them to temp#_max_alarm. Because lm_sensors v2 depends
on them.

Simplify fan and temp hyst. handling by treating the registers as an array of
nibbles instead of using switch cases. Also unify the way hysts are handled
between temp and fans, the temp code was storing the actual per temp hyst
values in 4 u8's, where as the fan code was storing actual register values.

While working on adding F8000 support I noticed that various of the
store sysfs functions (and a few of the show also) had issues.
This patch fixes the following issues in these functions:
* store: storing the result of strto[u]l in an int, resulting in a possible
overflow before boundary checking
* store: use of f71882fg_update_device(), we don't want to read the whole
device in store functions, just the registers we need
* store: use of cached register values instead of reading the needed regs
in the store function, including cases where f71882fg_update_device() was
not used, this could cause real isues
* show: shown value is a calculation of 2 or more cached register reads,
without locking the data struct.

This patch is a preparation patch for adding F8000 support to the f71882fg
driver. If you look at the register addresses and esp, the bits used for
the temperature channels, then you will notice that it appears that they
start at 1 in a system meant to start at 0. As the F8000 actually uses the 0
addresses and bits, this patch changes the f71882fg driver to take 4
temperatures numbered 0-3 in to account, using 1-3 in this new scheme for
the temperatures actually present in the F718x2FG.

Add PWM (fan speed control) support to the f71882fg driver. Both
manual control and automatic (temperature-based) modes are supported.
Additionally, each mode has a PWM-based and an RPM-based variant. By
default we use the mode set by the BIOS.

The __SWAB_64_THRU_32__ case of a 64-bit byte swap was depending on the
no-longer-existant ___swab32() method (three underscores). We got rid
of some of the worst indirection and complexity, and now it should just
use the 32-bit swab function that was defined right above it.

The first step to make swab.h a regular header that will
include an asm/swab.h with arch overrides.
Avoid the gratuitous differences introduced in the new
linux/swab.h by naming the ___constant_swabXX bits and
__fswabXX bits exactly as found in the old implementation
in byteorder/swab[b].h
Use this new swab.h in byteorder/[big|little]_endian.h and
remove the two old swab headers.
Although the inclusion of asm/byteorder.h looks strange in
linux/swab.h, this will allow each arch to move the actual
arch overrides for the swab bits in an asm file and then
the includes can be cleaned up without requiring a flag day
for all arches at once.
Keep providing __fswabXX in case some userspace was using them
directly, but the revised __swabXX should be used instead in
any new code and will always do constant folding not dependent
on the optimization level, which means the __constant versions
can be phased out in-kernel.
Arches that use the old-style arch macros will lose their
optimized versions until they move to the new style, but at
least they will still compile. Many arches have already moved
and the patches to move the remaining arches are trivial.

This avoids a BUG_ON in the enter_vt path due to objects being in the GTT
when we shouldn't have ever let them be (as we're not supposed to touch the
device during that time).
This was triggered by a change in the 2D driver to use the GTT mapping of
objects after pinning them to improve software fallback performance.
