acpi_device->pnp.hardware_id and unique_id are now allocated pointers,
replacing the previous arrays. acpi_device_install_notify_handler()
oopsed on the NULL hid when probing the video device, and perhaps other
uses are vulnerable too. So initialize those pointers to empty strings
when there is no hid or uid. Also, free hardware_id and unique_id when
when acpi_device is going to be freed.

Similar to commit b6adc195 (PCI hotplug: acpiphp wants a 64-bit
_SUN), pci_slot.ko reads and creates sysfs directories based on
the _SUN method.
Certain HP platforms return 64 bits in _SUN. This change to
pci_slot.ko allows us to see the correct sysfs directories.

In general, EC transaction should complete in less than 1ms, thus it is possible to merge wait for
1ms in poll mode and 1ms of interrupt transaction timeout.
Still, driver will wait 500ms for EC to complete transaction.
This significantly simplifies driver and makes it immune to problematic EC interrupt
implementations.
It also may lessen kernel start-up time by 500ms.

Acer Aspire 8930G laptops (and possibly others) report the battery current
as a 16-bit signed negative when it is charging. It also reports it as
0x10000 when the current is 0. This patch adds a quirk for this which
takes the absolute value of the reported current cast to an s16. This is
a DSDT bug present in the latest BIOS revision (the EC register is 16 bits
signed and the DSDT attempts to take the 16-bit two's complement of this,
which works for discharge but not charge. It also breaks zero values
because a 32-bit register is used and the high bits aren't thrown away).
I've enabled this for all Acer systems which report in mA units. This
should be safe since it won't break compliant systems unless they report a
current above 32A, which is insane. The patch also detects the valid
32-bit value -1, which indicates unknown status, and does not attempt the
fix in that case (note that this does not conflict with 16-bit -1, which
is 65535 as read normally and gets translated to 1mA).

If the dynamic region is created and added to resource list over and over again,
it has the potential to be a memory leak by growing the list every time.
This patch fixes the memory leak, as below
1) add a new field "count" to struct acpi_res_list.
When inserting, if the region(addr, len) is already in the resource
list, we just increase "count", otherwise, the region is inserted
with count=1.
When deleting, the "count" is decreased, if it's decreased to 0,
the region is deleted from the resource list.
With "count", the region with same address and length can only be
inserted to the resource list once, so prevent potential memory leak.
2) add a new function acpi_os_invalidate_address, which is called when
region is deleted.

Completed a major update for the acpi_get_object_info external interface.
Changes include:
- Support for variable, unlimited length HID, UID, and CID strings
- Support Processor objects the same as Devices (HID,UID,CID,ADR,STA, etc.)
- Call the _SxW power methods on behalf of a device object
- Determine if a device is a PCI root bridge
- Change the ACPI_BUFFER parameter to ACPI_DEVICE_INFO.
These changes will require an update to all callers of this interface.
See the ACPICA Programmer Reference for details.
Also, update all invocations of acpi_get_object_info interface

If the BIOS reports an invalid throttling state (which seems to be
fairly common after system boot), a reset is done to state T0.
Because of a check in acpi_processor_get_throttling_ptc(), the reset
never actually gets executed, which results in the error reoccurring
on every access of for example /proc/acpi/processor/CPU0/throttling.
Add a 'force' option to acpi_processor_set_throttling() to ensure
the reset really takes effect.

This patch, together with the next one, fixes a regression introduced in
2.6.30, listed on the regression list. They have been available for 2.5
months now in bugzilla, but have not been picked up, despite various
reminders and without any reason given.
Google shows that numerous people are hitting this issue. The issue is in
itself relatively minor, but the bug in the code is clear.
The patches have been in all my kernels and today testing has shown that
throttling works correctly with the patches applied when the system
overheats (http://bugzilla.kernel.org/show_bug.cgi?id=13918#c14).

Currently clockevents_notify() is called with interrupts enabled at
some places and interrupts disabled at some other places.
This results in a deadlock in this scenario.
cpu A holds clockevents_lock in clockevents_notify() with irqs enabled
cpu B waits for clockevents_lock in clockevents_notify() with irqs disabled
cpu C doing set_mtrr() which will try to rendezvous of all the cpus.
This will result in C and A come to the rendezvous point and waiting
for B. B is stuck forever waiting for the spinlock and thus not
reaching the rendezvous point.
Fix the clockevents code so that clockevents_lock is taken with
interrupts disabled and thus avoid the above deadlock.
Also call lapic_timer_propagate_broadcast() on the destination cpu so
that we avoid calling smp_call_function() in the clockevents notifier
chain.
This issue left us wondering if we need to change the MTRR rendezvous
logic to use stop machine logic (instead of smp_call_function) or add
a check in spinlock debug code to see if there are other spinlocks
which gets taken under both interrupts enabled/disabled conditions.

On some machines, a software-initiated SMI causes corruption unless the
SMI runs on CPU 0. An SMI can be initiated by any AML, but typically it's
done in GPE-related methods that are run via workqueues, so we can avoid
the known corruption cases by binding the workqueues to CPU 0.
