It seems that some watchdog drivers are doing following mistake:
rv = misc_register();
if (rv < 0)
return rv;
rv = request_region();
if (rv < 0) {
misc_deregister();
return rv;
}
But, right after misc_register() returns, misc device can be opened and
ioctls interacting with hardware issued, and driver can do outb() to
port it doesn't own yet, because request_region() is still pending.
Here is my patch, compile-tested only.

The rheap allocation functions return a pointer, but the actual value is based
on how the heap was initialized, and so it can be anything, e.g. an offset
into a buffer. A ulong is a better representation of the value returned by
the allocation functions.
This patch changes all of the relevant rheap functions to use a unsigned long
integers instead of a pointer. In case of an error, the value returned is
a negative error code that has been cast to an unsigned long. The caller can
use the IS_ERR_VALUE() macro to check for this.
All code which calls the rheap functions is updated accordingly. Macros
IS_MURAM_ERR() and IS_DPERR(), have been deleted in favor of IS_ERR_VALUE().
Also added error checking to rh_attach_region().

This patch changes the interrupt enable sequence for the sunzilog driver
so that interrupts are not enabled untill after the interrupt handler has
been installed. If this is not done, some SS1 and SS2 sun4c systems panic
on un-handled interrupt before the handler gets installed preventing boot.
It also adds in support for the ESCC version of the zilog chips. The
changes mean that the FIFO will be enabled for ESCC versions of the
SCC UART. My interpretation of the SCC manual and the existing interrupt
handler code is that it sould be able to make good use of the FIFO without
issues.

commands
The ACPI EC that is used in MSI laptops knows some non-standard
commands for changing the screen brighntess and a few other things,
which are used by the msi-laptop.c driver. Unfortunately for these
commands no GPE events for IBF and OBF are triggered. Since nowadays
the EC code uses the ec_intr=1 mode by default, this causes these
operations to timeout, although they don't fail. In result, all
operations that you can do with the msi-laptop.c driver take more or
less 1s to complete, which is awfully slow.
In one of the more recent kernels (2.6.20?) the EC subsystem has been
revamped. With that change the EC timeout has been increased. before
that increase the MSI EC accesses were slow -- but not *that* slow,
hence I took notice of this limitation of the MSI EC hardware only very
recently.
The standard EC operations on the MSI EC as defined in the ACPI spec
support GPE events properly.
The following patch adds a new argument "force_poll" to the
ec_transaction() function (and friends). If set to 1, the function
will poll for IBF/OBF even if ec_intr=1 is enabled. If set to 0 the
current behaviour is used. The msi-laptop driver is modified to make
use of this new flag, so that OBF/IBF is polled for the special MSI EC
transactions -- but only for them.

HP nx6125/nx6325/... machines have a _GPE handler with an infinite
loop sending Notify() events to different ACPI subsystems.
Notify handler in ACPI driver is a C-routine, which may call ACPI
interpreter again to get access to some ACPI variables
(acpi_evaluate_xxx).
On these HP machines such an evaluation changes state of some variable
and lets the loop above break.
In the current ACPI implementation Notify requests are being deferred
to the same kacpid workqueue on which the above GPE handler with
infinite loop is executing. Thus we have a deadlock -- loop will
continue to spin, sending notify events, and at the same time
preventing these notify events from being run on a workqueue. All
notify events are deferred, thus we see increase in memory consumption
noticed by author of the thread. Also as GPE handling is bloked,
machines overheat. Eventually by external poll of the same
acpi_evaluate, kacpid is released and all the queued notify events are
free to run, thus 100% cpu utilization by kacpid for several seconds
or more.
To prevent all these horrors it's needed to not put notify events to
kacpid workqueue by either executing them immediately or putting them
on some other thread. It's dangerous to execute notify events in
place, as it will put several ACPI interpreter stacks on top of each
other (at least 4 in case of nx6125), thus causing kernel stack
overflow.
First attempt to create a new thread was done by Peter Wainwright
He created a bunch of threads, which were stealing work from a kacpid
workqueue.
This patch appeared in 2.6.15 kernel shipped with Ubuntu 6.06 LTS.
Second attempt was done by me, I created a new thread for each Notify
event. This worked OK on HP nx machines, but broke Linus' Compaq
n620c, by producing threads with a speed what they stopped the machine
completely. Thus this patch was reverted from 18-rc2 as I remember.
I re-made the patch to create second workqueue just for notify events,
thus hopping it will not break Linus' machine. Patch was tested on the
same HP nx machines in #5534 and #7122, but I did not received reply
from Linus on a test patch sent to him.
Patch went to 19-rc and was rejected with much fanfare again.
There was 4th patch, which inserted schedule_timeout(1) into deferred
execution of kacpid, if we had any notify requests pending, but Linus
decided that it was too complex (involved either changes to workqueue
to see if it's empty or atomic inc/dec).
Now you see last variant which adds yield() to every GPE execution.

This reverts commit c0d127b56937c3e72c2b1819161d2f6718eee877.
These changes to AML locking were made to allow
Notify handlers to be called on the stack
and not deadlock. However, that scheme turns
out to be flawed and was reverted by the previous commit,
so this commit restores the locking to it previous design.

This reverts commit 5f7748cf91558a5026ded5be93c5bf6c1ac34edf.
While that change fixed the HP
http://bugzilla.kernel.org/show_bug.cgi?id=5534
it broke the ACER:
http://bugzilla.kernel.org/show_bug.cgi?id=8385
which as AML that caused Linux go recursive
and stack fault.
So this commit by itself will restore the ACER
and again break the HP, which we'll fix another way.

This reverts commit a8f4af6dc6600980885c594f52eecd60edd62013.
Thus restoring ACPICA's new acpi_serialize code.
This commit by itself may cause a regression, but
it is reverted in this order so that subsequent
reverts reverts under this one can be made
without conflict.

The scheme where the thermal driver displayed the
cooling mode /proc/acpi/thermal_zone/*/cooling_mode
was flawed in two ways.
First, the success of _SCP doesn't actually mean
that the BIOS moved any trip points.
On many BIOS, _SCP is present, but does nothing.
So displaying what _SCP executed actually
was wrong more times than it was right.
Second, examining the relative position of the
trip points when the thermal_zone is added
is insufficient -- as the BIOS reserves the right
to change the trip points at run-time.
The only reliable way for the user to determine if
the thermal zone is in active, passive, or critical
mode is to examine the relative position of the trip points.
The user can do this without the kernel doing it
for them by looking in /proc/acpi/thermal_zone/*/trip_points
New contents for /proc/acpi/thermal_zone/*/cooling_mode:
If _SCP available:
"0 - Active; 1 - Passive\n"
If _SCP unavailable:
"<setting not supported>\n"

/proc/acpi/thermal_zone/*/trip_points displays
what the kernel reads from the BIOS via ACPI.
If you echo a string of ':' deliminted numbers to this file
then it will change what it displays.
But it shouldn't, since the kernel has no way to communicate
these changes to ACPI thermal zones. ACPI thermal zone
trip points are read-only.
The kernel does have the opportunity to ask the BIOS to change
the trip points with _SCP - Set Cooling Policy.
Request Active Cooling Mode:
# echo 0 > /proc/acpi/thermal_zone/*/cooling_policy
Request Passive Cooling Mode:
# echo 1 > /proc/acpi/thermal_zone/*/cooling_policy
However, in practice it is quite rare for the BIOS
to support the optional _SCP, and it is even more rare
for the BIOS to export an _SCP that actually changes
the trip points.

The SCSI layer only passes sg requests down, so drop the
use_sg == 0, request_bufflen != 0 case.
