1496e89ae2 powerpc/therm_adt746x: Record pwm invert bit at module load time]
In commit 0512a9a8e2, we unilaterally zero the
"pwm invert" bit in the fan behavior configuration register.  On my PowerBook
G4, this results in the fans going to full speed at low temperature and
shutting off at high temperature because the pwm invert bit is supposed to be
set.

Therefore, record the pwm invert bit at driver load time, and write the bit
into the fan behavior control register.  This restores correct behavior on my
PBG4 and should work around the bit being set to the wrong value after
suspend/resume (which is what the original patch was trying to fix).  It also
fixes a minor omission where the pwm invert bit correction is NOT performed
when switching into automatic mode.

d58b0c39e3 powerpc/macio: Rework hotplug media bay support
The hotplug mediabay has tendrils deep into drivers/ide code
which makes a libata port reather difficult. In addition it's
ugly and could be done better.

This reworks the interface between the mediabay and the rest
of the world so that:

   - Any macio_driver can now have a mediabay_event callback
which will be called when that driver sits on a mediabay and
it's been either plugged or unplugged. The device type is
passed as an argument. We can now move all the IDE cruft
into the IDE driver itself

   - A check_media_bay() function can be used to take a peek
at the type of device currently in the bay if any, a cleaner
variant of the previous function with the same name.

   - A pair of lock/unlock functions are exposed to allow the
IDE driver to block the hotplug callbacks during the initial
setup and probing of the bay in order to avoid nasty race
conditions.

   - The mediabay code no longer needs to spin on the status
register of the IDE interface when it detects an IDE device,
this is done just fine by the IDE code itself

Overall, less code, simpler, and allows for another driver
than our old drivers/ide based one.

0b048c7a1d macintosh: Remove BKL from nvram driver
Drop the bkl from nvram_llseek() as it obviously protects nothing. The
file offset is safe in essence.

The ioctl can be converted to unlocked_ioctl because it just calls
pmac_get_partition() which reads a value from an array which was
initialized at early boot time. No need for serialization.

95fdac7372 macintosh: Remove BKL from ans-lcd
The ans-lcd driver got the cycle_kernel_lock() in anslcd_open() from
the BKL pushdown and it still uses the locked ioctl.

The BKL serialization in this driver is more than obscure and
definitely does not cover all possible corner cases. Protect the
access to the hardware with a local mutex and get rid of BKL and
locked ioctl.

11a50873ef powerpc/pmac: Fix issues with sleep on some powerbooks
Since the change of how interrupts are disabled during suspend,
certain PowerBook models started exhibiting various issues during
suspend or resume from sleep.

I finally tracked it down to the code that runs various "platform"
functions (kind of little scripts extracted from the device-tree),
which uses our i2c and PMU drivers expecting interrutps to work,
and at a time where with the new scheme, they have been disabled.

This causes timeouts internally which for some reason results in
the PMU being unable to see the trackpad, among other issues, really
it depends on the machine. Most of the time, we fail to properly adjust
some clocks for suspend/resume so the results are not always
predictable.

This patch fixes it by using IRQF_TIMER for both the PMU and the I2C
interrupts. I prefer doing it this way than moving the call sites since
I really want those platform functions to still be called after all
drivers (and before sysdevs).

We also do a slight cleanup to via-pmu.c driver to make sure the
ADB autopoll mask is handled correctly when doing bus resets

b8e4a7dae5 powerpc/powermac: Thermal control turns system off too eagerly
On certain PowerMacs, a module (therm_windtunnel) controls various
thermal settings (it can report CPU/case temperature, change speed
of internal fans, etc.)

By default, the hardware thermal control has a temperature limit to
protect the computer from damages (the default limit seems to be 80°C)
but therm_windtunnel.c reduces it to an anormaly low value (65°C),
which means that he computer will shut down randomly when hit by direct
sun light or during summer (summer in France can be quite hot), actually
possibly losing data instead of protecting it.

The overheat limit in therm_windtunnel.c:253-254 should be set to 75°C
and 70°C instead of 65°C and 60°C respectively.

44ea9c809d drivers/macintosh: Add missing of_node_put in therm_adt746x.c
of_node_put is needed before discarding a value received from
of_find_node_by_name, eg in error handling code or when the device node is
no longer used.

It is always "an" if there is a vowel _spoken_ (not written).
So it is:
"an hour" (spoken vowel)
but
"a uniform" (spoken 'j')
