The ACPI BGRT driver accesses the BIOS logo image when it initializes.
However, ACPI 5.0 (which introduces the BGRT) recommends putting the
logo image in EFI boot services memory, so that the OS can reclaim that
memory. Production systems follow this recommendation, breaking the
ACPI BGRT driver.
Move the bulk of the BGRT code to run during a new EFI late
initialization phase, which occurs after switching EFI to virtual mode,
and after initializing ACPI, but before freeing boot services memory.
Copy the BIOS logo image to kernel memory at that point, and make it
accessible to the BGRT driver. Rework the existing ACPI BGRT driver to
act as a simple wrapper exposing that image (and the properties from the
BGRT) via sysfs.

This patch changes the implementation of acpi_pci_find_root().
We can access acpi_pci_root without scanning acpi_pci_roots list.
If hostbridge hotplug is supported, acpi_pci_roots list will be
protected by mutex. We should not access acpi_pci_roots list
if preventable to lessen deadlock risk.

This patch changes the function signature of walk_root_bridge().
We can omit _STA, _SEG, and _BBN evaluation by passing not acpi_handle
but acpi_pci_root. Now that acpi_pci_slot_add() which is the only
caller of walk_root_bridge() gets acpi_pci_root structure, changing
signature of walk_root_bridge() is reasonable.

This patch changes .add/.remove interfaces of acpi_pci_driver.
In the current implementation acpi_handle is passed as a parameter
of .add/.remove interface. However, the acpi_pci_root structure
contains more useful information than just the acpi_handle. This
enables us to avoid some useless lookups in each acpi_pci_driver.
Note: This changes interfaces used by acpi_pci_register_driver(), an
exported symbol. This patch updates all the in-kernel users, but any
out-of-kernel acpi_pci_register_driver() users will need updates.

Commit 0090def("ACPI: Add interface to register/unregister device
to/from power resources") used resource_lock to protect the devices list
that relies on power resource. It caused a mutex dead lock, as below
acpi_power_on ---> lock resource_lock
__acpi_power_on
acpi_power_on_device
acpi_power_get_inferred_state
acpi_power_get_list_state ---> lock resource_lock
This patch adds a new mutex "devices_lock" to protect the devices list
and calls acpi_power_on_device in acpi_power_on, instead of
__acpi_power_on, after the resource_lock is released.

It turns out that there are ACPI BIOSes defining device objects with
_PSx and without either _PSC or _PRx. For devices corresponding to
those ACPI objetcs __acpi_bus_get_power() returns ACPI_STATE_UNKNOWN
and their initial power states are regarded as unknown as a result.
If such a device is a parent of another power-manageable device, the
child cannot be put into a low-power state through ACPI, because
__acpi_bus_set_power() refuses to change power states of devices
whose parents' power states are unknown.
To work around this problem, observe that the ACPI power state of
a device cannot be higher-power (lower-number) than the power state
of its parent. Thus, if the device's _PSC method or the
configuration of its power resources indicates that the device is
in D0, the device's parent has to be in D0 as well. Consequently,
if the parent's power state is unknown when we've just learned that
its child's power state is D0, we can safely set the parent's
power.state field to ACPI_STATE_D0.

If acpi_pci_osc_support() fails for the given flags, it doesn't make
sense to call acpi_pci_osc_control_set() down the road for the same
flags, because it will certainly fail too. Moreover, problem
diagnostics is then harder, because it is not too easy to identify
the reason of the _OSC failure in those cases.
For this reason, check the status returned by acpi_pci_osc_support()
for PCIe support flags and do not attempt to execute
acpi_pci_osc_control_set() for those flags and print a message if
it's "failure". For compatibility with the existing code, disable
ASPM in that case too.

_GTS and _BFS were added to the suspend/resume flow
in the ACPI 2.0 specification.
Linux dutifully implemented _GTS and _BFS.
We discovered that it was rarely seen in systems
in the field. Further, some of those systems had
AML so bogus that it could never work -- proof that
no other operating system supports _GTS and _BFS.
So we made _GTS and _BFS optional via modparam,
and disabled them by default.
But we've had to complicate some code to keep
this support in the kernel, as these methods are defined
to be evaluated very close to sleep entry and exit.
Indeed, no other AML is ever evaluated with interrupts off.
We have submitted a proposal for _GTS and _BFS
to be officially removed from the ACPI specification
on the next revision. Here we remove it from Linux.

Pull PCI changes from Bjorn Helgaas:
"Host bridge hotplug:
- Add MMCONFIG support for hot-added host bridges (Jiang Liu)
Device hotplug:
- Move fixups from __init to __devinit (Sebastian Andrzej Siewior)
- Call FINAL fixups for hot-added devices, too (Myron Stowe)
- Factor out generic code for P2P bridge hot-add (Yinghai Lu)
- Remove all functions in a slot, not just those with _EJx (Amos
Kong)
Dynamic resource management:
- Track bus number allocation (struct resource tree per domain)
(Yinghai Lu)
- Make P2P bridge 1K I/O windows work with resource reassignment
(Bjorn Helgaas, Yinghai Lu)
- Disable decoding while updating 64-bit BARs (Bjorn Helgaas)
Power management:
- Add PCIe runtime D3cold support (Huang Ying)
Virtualization:
- Add VFIO infrastructure (ACS, DMA source ID quirks) (Alex
Williamson)
- Add quirks for devices with broken INTx masking (Jan Kiszka)
Miscellaneous:
- Fix some PCI Express capability version issues (Myron Stowe)
- Factor out some arch code with a weak, generic, pcibios_setup()
(Myron Stowe)"

PCI: support sizing P2P bridge I/O windows with 1K granularity
PCI: reimplement P2P bridge 1K I/O windows (Intel P64H2)
PCI: disable MEM decoding while updating 64-bit MEM BARs
PCI: leave MEM and IO decoding disabled during 64-bit BAR sizing, too
PCI: never discard enable/suspend/resume_early/resume fixups
PCI: release temporary reference in __nv_msi_ht_cap_quirk()
PCI: restructure 'pci_do_fixups()'
...
In the ac.c, power_supply_register()'s return value is not checked.
As a result, the driver's add() ops may return success
even though the device failed to initialize.
For example, some BIOS may describe two ACADs in the same DSDT.
The second ACAD device will fail to register,
but ACPI driver's add() ops returns sucessfully.
The ACPI device will receive ACPI notification and cause OOPS.

Fixes issues like this:
i_aSL -> iASL
00-7_f -> 00-7F
local_fADT -> local_FADT
execute_oSI -> execute_OSI
Also, in function headers, the parameters are now translated to
lower case (with underscores if necessary.)

These new interfaces will be deployed across ACPICA in order to
point a finger directly at any detected BIOS issues -- such as
issues with ACPI tables, etc.
