Based on a patch from Peter Oruba, convert myri10ge to use pcie_get_readrq()
and pcie_set_readrq() instead of our own PCI calls and arithmetics.
These driver changes incorporate the proposed PCI-X / PCI-Express read byte
count interface. Reading and setting those values doesn't take place
"manually", instead wrapping functions are called to allow quirks for some
PCI bridges.

This fixes the extra timer overhead that people were whining about
as a 2.6.23 regression.
Running the watchdog timer all the time is unneeded. Change it
to run only if link is up, and reduce frequency to save power.

When transferring data at full speed, the DM9000 network interface
sometimes stops sending/receiving data. Worse, ksoftirqd consumes
100% cpu and the net tx watchdog never triggers.
Fix by spin_lock_irqsave() in dm9000_start_xmit() to prevent the
interrupt handler from interfering.

This can only fix the problem that more than one video bus device
have the same AML name "VID".
ie. the proc I/F for the second "VID" video bus device is located under
/proc/acpi/video/VID1/...
As this is really rare and the ACPI proc I/F is a legacy feature that
we are planning to remove.
We won't provide a generic solution for this problem.

The previous events patch added a netlink event for every
user of the legacy /proc/acpi/event interface.
However, some users of /proc/acpi/event are really input events,
and they already report their events via the input layer.
Introduce a new interface, acpi_bus_generate_netlink_event(),
which is explicitly called by devices that want to repoprt
events via netlink. This allows the input-like events
to opt-out of generating netlink events. In summary:
events that are sent via netlink:
ac/battery/sbs
thermal
processor
thinkpad_acpi dock/bay
events that are sent via input layer:
button
video hotkey
thinkpad_acpi hotkey
asus_acpi/asus-laptop hotkey
sonypi/sonylaptop

It seems it's required to enable GPEs before _WAK. E.g. X60 triggers a
LID related GPE instead of doing a Notify in WAK. Now the GPE reaches the
kernel and the Notify for LID status change gets thrown from there.

Both ACPI_VIDEO_NOTIFY_SWITCH and ACPI_VIDEO_NOTIFY_PROBE
are valid for video bus devices only. Actually ACPI video output
device should never be notified for a output device switch/probe.
ACPI bus devices notify handler already has the code to

Some hardware will malfunction at a temperature below

This hook allows moving the critical trip points down
to a temperature which provokes a graceful shutdown
before the hardware malfunction.

until the system delivers a temperature change event,
or unless thermal zone polling is enabled.

ISAPNP_DEBUG isn't used at all. isapnp_detected is set but never read.
So remove them both.

No need for a temporary variable; just return the flags once we know them.

ACPI 1.0 used an RSDT with 32-bit physical addresses.
ACPI 2.0 adds an XSDT with 32-bit physical addresses.
An ACPI 2.0 aware OS is supposed to use the XSDT
(when present) instead of the RSDT.
However, several systems have failed because the XSDT
contains NULL entries -- while it is missing pointers
to needed tables, such as SSDTs.
When we find an XSDT with NULL entries, discard it
and use the ACPI 1.0 RSDT instead.
