991de2e590 ("PCI, x86: Implement pcibios_alloc_irq() and
pcibios_free_irq()") appeared in v4.3 and helps support IOAPIC hotplug.
Олег reported that the Elcus-1553 TA1-PCI driver worked in v4.2 but not
v4.3 and bisected it to 991de2e590. Sunjin reported that the RocketRAID
272x driver worked in v4.2 but not v4.3. In both cases booting with
"pci=routirq" is a workaround.
I think the problem is that after 991de2e590, we no longer call
pcibios_enable_irq() for upstream bridges. Prior to 991de2e590, when a
driver called pci_enable_device(), we recursively called
pcibios_enable_irq() for upstream bridges via pci_enable_bridge().
After 991de2e590, we call pcibios_enable_irq() from pci_device_probe()
instead of the pci_enable_device() path, which does *not* call
pcibios_enable_irq() for upstream bridges.
Revert 991de2e590 to fix these driver regressions.

ACPICA commit 19f84c249267fab0bfb138bd14d12510fb4faf24
The global variable actually means the availability of the namespace, and
control methods evaluations should happen after namespace readiness. Thus
this patch renames the global variable to reflect this logic. Lv Zheng.

ACPICA commit 8ae25b8d128b6b8509010be321ff6bf2760f3807
There is BIOS code relying on the fact that \_SB._INI should get evaluated
before any other control methods. This may implies a gap in ACPICA/Linux
initialization/enumeration process.
Before revealing Windows true behavior by more validations, this patch only
ensures \_SB._INI evaluated before any _REG control methods. This can help
to make progress to other initialization order fixes. Lv Zheng.

ACPICA commit 77e0c7a482ac30ef857cf3c33d075e5fe5b5e449
This patch tunes _REG evaluations to be later than all table loading
facilities:
1. acpi_load_tables(): _REG is currently invoked after this function.
2. acpi_ns_exec_module_code_list(): this executes module level code, the
execution should be a part of the table loading while we currently
support this in a deferred way.
3. acpi_ns_initialize_objects(): this parses Region/Field/Buffer/Package where
pkg_length primitive can be seen in the grammar, the parsing should be a
part of the table loading while we currently support this in a deferred
way.
Control method evaluation should happen after loading the tables. So this
patch changes the order of _REG evaluation when
acpi_gbl_group_module_level_code experiment is enabled. Lv Zheng.

It is proven that the default regions should be accessible during the
table loading in order to execute module level AML code.
This patch moves default region handler installation code earlier in
order to make this happen.
Note that by putting the code here, we actually allow OSPMs to override
default region handlers between acpi_initialize_subsystem() and
acpi_load_tables(), without the need to introduce region handler override
mechanism in acpi_install_address_space_handler(). OSPMs are also couraged
to check acpi_install_address_space_handler() return value to determine if
acpi_remove_address_space_handler() should be invoked before installing new
address space handler. Lv Zheng.

The original format of these commands from the "NVDIMM DSM Interface
Example" [1] are superseded by the ACPI 6.1 definition of the "NVDIMM Root
Device _DSMs" [2].

[2]: http://www.uefi.org/sites/default/files/resources/ACPI_6_1.pdf
"9.20.7 NVDIMM Root Device _DSMs"
Changes include:
1/ New 'restart' fields in ars_status, unfortunately these are
implemented in the middle of the existing definition so this change
is not backwards compatible. The expectation is that shipping
platforms will only ever support the ACPI 6.1 definition.
2/ New status values for ars_start ('busy') and ars_status ('overflow').

acpi_processor_sleep is neither related nor used by CPUIdle framework.
It's used in system suspend/resume path as a syscore operation. It makes
more sense to move it to acpi/sleep.c where all the S-state transition
(a.k.a. Linux system suspend/hiberate) related code are present.
Also make it depend on CONFIG_ACPI_SYSTEM_POWER_STATES_SUPPORT so that
it's not compiled on architecture like ARM64 where S-states are not
yet defined in ACPI.

ACPI 6.0 adds support for optional processor container device which may
contain child objects that are either processor devices or other processor
containers. This allows representing hierarchical processor topologies.
It is declared using the _HID of ACPI0010. It is an abstract container
used to represent CPU topology and should not be used to hotplug
purposes.
If no matching handler is found for a device in acpi_scan_attach_handler,
acpi_bus_attach does a default enumeration for those devices with valid
HID in the acpi namespace. This patch adds a scan handler for these ACPI
processor containers to avoid default that enumeration and ensures the
platform devices are not created for them.

ACPI 6.1 clarified that multi-interface dimms require multiple control
region entries (DCRs) per dimm. Previously we were assuming that a
control region is only present when block-data-windows are present.
This implementation was done with an eye to be compatibility with the
looser ACPI 6.0 interpretation of this table.
1/ When coalescing the memory device (MEMDEV) tables for a single dimm,
coalesce on device_handle rather than control region index.
2/ Whenever we disocver a control region with non-zero block windows
re-scan for block-data-window (BDW) entries.
We may need to revisit this if a DIMM ever implements a format interface
outside of blk or pmem, but that is not on the foreseeable horizon.

In the case of memory error injection, einj_error_inject()
checks if a target address is System RAM. Change this check to
allow injecting a memory error into NVDIMM memory by calling
region_intersects() with IORES_DESC_PERSISTENT_MEMORY. This
enables memory error testing on both System RAM and NVDIMM.
In addition, page_is_ram() is replaced with region_intersects()
with IORESOURCE_SYSTEM_RAM, so that it can verify a target
address range with the requested size.

The quirk to get "acpi_backlight=vendor" behavior by default on the

"acpi_backlight=native" by default on Win8 ready machines.
Since we now avoid using acpi-video as backlight driver on these machines
by default (using the native driver instead) we no longer need this quirk.
Moreover the vendor driver does not work after a suspend/resume where
as the native driver does.

Merge tag 'pm+acpi-4.5-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull more power management and ACPI updates from Rafael Wysocki:
"This includes fixes on top of the previous batch of PM+ACPI updates
and some new material as well.
From the new material perspective the most significant are the driver
core changes that should allow USB devices to stay suspended over
system suspend/resume cycles if they have been runtime-suspended
already beforehand. Apart from that, ACPICA is updated to upstream
revision 20160108 (cosmetic mostly, but including one fixup on top of
the previous ACPICA update) and there are some devfreq updates the
didn't make it before (due to timing).
A few recent regressions are fixed, most importantly in the cpuidle
menu governor and in the ACPI backlight driver and some x86 platform
drivers depending on it.
Some more bugs are fixed and cleanups are made on top of that.
Specifics:
- Modify the driver core and the USB subsystem to allow USB devices
to stay suspended over system suspend/resume cycles if they have
been runtime-suspended already beforehand and fix some bugs on top
of these changes (Tomeu Vizoso, Rafael Wysocki).
- Update ACPICA to upstream revision 20160108, including updates of
the ACPICA's copyright notices, a code fixup resulting from a
regression fix that was necessary in the upstream code only (the
regression fixed by it has never been present in Linux) and a
compiler warning fix (Bob Moore, Lv Zheng).
- Fix a recent regression in the cpuidle menu governor that broke it
on practically all architectures other than x86 and make a couple
of optimizations on top of that fix (Rafael Wysocki).
- Clean up the selection of cpuidle governors depending on whether or
not the kernel is configured for tickless systems (Jean Delvare).
- Revert a recent commit that introduced a regression in the ACPI
backlight driver, address the problem it attempted to fix in a
different way and revert one more cosmetic change depending on the
problematic commit (Hans de Goede).
- Add two more ACPI backlight quirks (Hans de Goede).
- Fix a few minor problems in the core devfreq code, clean it up a
bit and update the MAINTAINERS information related to it (Chanwoo
Choi, MyungJoo Ham).
- Improve an error message in the ACPI fan driver (Andy Lutomirski).
- Fix a recent build regression in the cpupower tool (Shreyas
Prabhu)"

Merge tag 'libnvdimm-for-4.5' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm
Pull libnvdimm updates from Dan Williams:
"The bulk of this has appeared in -next and independently received a
build success notification from the kbuild robot. The 'for-4.5/block-
dax' topic branch was rebased over the weekend to drop the "block
device end-of-life" rework that Al would like to see re-implemented
with a notifier, and to address bug reports against the badblocks
integration.
There is pending feedback against "libnvdimm: Add a poison list and
export badblocks" received last week. Linda identified some localized
fixups that we will handle incrementally.
Summary:
- Media error handling: The 'badblocks' implementation that
originated in md-raid is up-levelled to a generic capability of a
block device. This initial implementation is limited to being
consulted in the pmem block-i/o path. Later, 'badblocks' will be

This is a third approach to workaround long standing issue with LPSS on
BayTrail. First one [1] was reverted since it didn't resolve the issue
comprehensively. Second one [2] was rejected by internal review.
The LPSS DMA controller does not have neither _PS0 nor _PS3 method. Moreover it
can be powered off automatically whenever the last LPSS device goes down. In
case of no power any access to the DMA controller will hang the system. The
behaviour is reproduced on some HP laptops based on Intel BayTrail [3,4] as
well as on ASuS T100TA transformer.

The error has been reported by lockdep: DEBUG_LOCKS_WARN_ON(l->magic != l).
The function assumes that the video driver has been registered before being
called. As explained in the comment of acpi_video_init(), the registration
of the video class may be defered and thus may not take place in the init
function of the module.
Use completion mechanisms to make sure that
acpi_video_handles_brightness_key_presses() wait for the completion of
acpi_video_register() before using the mutex.

Commit f06147f9fb (ACPICA: Hardware: Enable firmware waking vector
for both 32-bit and 64-bit FACS) added three functions that aren't
present in upstream ACPICA, acpi_hw_set_firmware_waking_vectors(),
acpi_set_firmware_waking_vectors() and acpi_set_firmware_waking_vector64(),
to allow Linux to use the previously existing API for setting the
platform firmware waking vector.
However, that wasn't necessary, since the ACPI sleep support code
in Linux can be modified to use the upstream ACPICA's API easily
and the additional functions may be dropped which reduces the code
size and puts the kernel's ACPICA code more in line with the upstream.
Make the changes as per the above. While at it, make the relevant
function desctiption comments reflect the upstream ACPICA's ones.

ACPICA commit 1cf1a1e090f61f0c27f1dcf1905c7cc79a9c51c8
It is likely that we should synchronously invoke _REG(DISCONNECT) only when
the acpi_remove_address_space_handler() is invoked because of dependencies.
If it is invoked when the object is not referenced, problem may occur
if the operation region fields accessed in _REG are no longer driven by any
device driver.
Noticed that _REG(CONNECT)/_REG(DISCONNECT) only mean to inform the AML of
the handler availability, no return value is required for the caller.
This patch only introduces ACPI_REG_DISCONNECT invaocation, but doesn't
introduce a real change. Lv Zheng.

ACPICA commit 31178590dde82368fdb0f6b0e466b6c0add96c57
We can ensure no early _REG evaluations by ensuring the following rules in
acpi_ev_execute_reg_method():
1. If an address space handler is installed during early stage,
_REG(CONNECT) evaluations are blocked. This is achieved using
acpi_gbl_reg_methods_enabled which is renamed from
acpi_gbl_reg_methods_executed.
2. If _REG(CONNECT) has never been evalauted for the region object,
_REG(DISCONNECT) evaluations are blocked. This is achieved by a new
region object flag: AOPOBJ_REG_CONNECTED.
Note that, after applying this patch, we can ensure _REG(DISCONNECT) is
always paired to _REG(CONNECT). Lv Zheng

ACPICA commit 87c85610250ff7141a84507f68dbc1e00f2936db
This patch introduces a new region initialization function
acpi_ev_associate_reg_method(), which is invoked to associate the _REG method
to its related region object.
Region object's default value assignments are also sorted by cleaning up
the code using this new function. Lv Zheng.

The _SUB method was found to be problematic for this interface

it is being removed.
Operations cannot be used because this interface is called
during the device discovery scan and the region handlers are
not fully installed at that time.
