code path in the ACPI LPSS (Low-Power Subsystem) driver (Rafael J
Wysocki).

- Fix for a leftover dangling pointer in an error code path in the
new wakeup IRQ support code (Rafael J Wysocki).

- Fix to prevent infinite loops (due to errors in other places) from
happening in the core generic PM domains support code (Geert
Uytterhoeven).

- Hibernation documentation update/clarification (Uwe Geuder).

ACPI / PNP: Reserve ACPI resources at the fs_initcall_sync stage

This effectively reverts the following three commits:

7bc10388ccdd ACPI / resources: free memory on error in add_region_before()
0f1b414d1907 ACPI / PNP: Avoid conflicting resource reservations
b9a5e5e18fbf ACPI / init: Fix the ordering of acpi_reserve_resources()

(commit b9a5e5e18fbf introduced regressions some of which, but not
all, were addressed by commit 0f1b414d1907 and commit 7bc10388ccdd
was a fixup on top of the latter) and causes ACPI fixed hardware
resources to be reserved at the fs_initcall_sync stage of system
initialization.

The story is as follows. First, a boot regression was reported due
to an apparent resource reservation ordering change after a commit
that shouldn't lead to such changes. Investigation led to the
conclusion that the problem happened because acpi_reserve_resources()
was executed at the device_initcall() stage of system initialization
which wasn't strictly ordered with respect to driver initialization
(and with respect to the initialization of the pcieport driver in
particular), so a random change causing the device initcalls to be
run in a different order might break things.

The response to that was to attempt to run acpi_reserve_resources()
as soon as we knew that ACPI would be in use (commit b9a5e5e18fbf).
However, that turned out to be too early, because it caused resource
reservations made by the PNP system driver to fail on at least one
system and that failure was addressed by commit 0f1b414d1907.

That fix still turned out to be insufficient, though, because
calling acpi_reserve_resources() before the fs_initcall stage of
system initialization caused a boot regression to happen on the
eCAFE EC-800-H20G/S netbook. That meant that we only could call
acpi_reserve_resources() at the fs_initcall initialization stage
or later, but then we might just as well call it after the PNP
initalization in which case commit 0f1b414d1907 wouldn't be
necessary any more.

For this reason, the changes made by commit 0f1b414d1907 are reverted
(along with a memory leak fixup on top of that commit), the changes
made by commit b9a5e5e18fbf that went too far are reverted too and
acpi_reserve_resources() is changed into fs_initcall_sync, which
will cause it to be executed after the PNP subsystem initialization
(which is an fs_initcall) and before device initcalls (including
the pcieport driver initialization) which should avoid the initial
issue.

Merge tag 'pm+acpi-4.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull power management and ACPI updates from Rafael Wysocki:
"The rework of backlight interface selection API from Hans de Goede
stands out from the number of commits and the number of affected
places perspective. The cpufreq core fixes from Viresh Kumar are
quite significant too as far as the number of commits goes and because
they should reduce CPU online/offline overhead quite a bit in the
majority of cases.

From the new featues point of view, the ACPICA update (to upstream
revision 20150515) adding support for new ACPI 6 material to ACPICA is
the one that matters the most as some new significant features will be
based on it going forward. Also included is an update of the ACPI
device power management core to follow ACPI 6 (which in turn reflects
the Windows' device PM implementation), a PM core extension to support
wakeup interrupts in a more generic way and support for the ACPI _CCA
device configuration object.

The rest is mostly fixes and cleanups all over and some documentation
updates, including new DT bindings for Operating Performance Points.

There is one fix for a regression introduced in the 4.1 cycle, but it
adds quite a number of lines of code, it wasn't really ready before
Thursday and you were on vacation, so I refrained from pushing it on
the last minute for 4.1.

Specifics:

- ACPICA update to upstream revision 20150515 including basic support
for ACPI 6 features: new ACPI tables introduced by ACPI 6 (STAO,
XENV, WPBT, NFIT, IORT), changes related to the other tables (DTRM,
FADT, LPIT, MADT), new predefined names (_BTH, _CR3, _DSD, _LPI,
_MTL, _PRR, _RDI, _RST, _TFP, _TSN), fixes and cleanups (Bob Moore,
Lv Zheng).

- ACPI device power management core code update to follow ACPI 6
which reflects the ACPI device power management implementation in
Windows (Rafael J Wysocki).

- rework of the backlight interface selection logic to reduce the
number of kernel command line options and improve the handling of
DMI quirks that may be involved in that and to make the code
generally more straightforward (Hans de Goede).

- fixes for the ACPI Embedded Controller (EC) driver related to the
handling of EC transactions (Lv Zheng).

- fix for a regression related to the ACPI resources management and
resulting from a recent change of ACPI initialization code ordering
(Rafael J Wysocki).

- fix for a system initialization regression related to ACPI
introduced during the 3.14 cycle and caused by running the code
that switches the platform over to the ACPI mode too early in the
initialization sequence (Rafael J Wysocki).

- support for the ACPI _CCA device configuration object related to
DMA cache coherence (Suravee Suthikulpanit).

- ACPI/APEI fixes and cleanups (Jiri Kosina, Borislav Petkov).

- ACPI battery driver cleanups (Luis Henriques, Mathias Krause).

- ACPI processor driver cleanups (Hanjun Guo).

- cleanups and documentation update related to the ACPI device
properties interface based on _DSD (Rafael J Wysocki).

- ACPI device power management fixes (Rafael J Wysocki).

- assorted cleanups related to ACPI (Dominik Brodowski, Fabian
Frederick, Lorenzo Pieralisi, Mathias Krause, Rafael J Wysocki).

- fix for a long-standing issue causing General Protection Faults to
be generated occasionally on return to user space after resume from
ACPI-based suspend-to-RAM on 32-bit x86 (Ingo Molnar).

- fix to make the suspend core code return -EBUSY consistently in all
cases when system suspend is aborted due to wakeup detection (Ruchi
Kandoi).

- support for automated device wakeup IRQ handling allowing drivers
to make their PM support more starightforward (Tony Lindgren).

- new tracepoints for suspend-to-idle tracing and rework of the
prepare/complete callbacks tracing in the PM core (Todd E Brandt,
Rafael J Wysocki).

- wakeup sources framework enhancements (Jin Qian).

- new macro for noirq system PM callbacks (Grygorii Strashko).

- assorted cleanups related to system suspend (Rafael J Wysocki).

- cpuidle core cleanups to make the code more efficient (Rafael J
Wysocki).

- powernv/pseries cpuidle driver update (Shilpasri G Bhat).

- cpufreq core fixes related to CPU online/offline that should reduce
the overhead of these operations quite a bit, unless the CPU in
question is physically going away (Viresh Kumar, Saravana Kannan).

- serialization of cpufreq governor callbacks to avoid race
conditions in some cases (Viresh Kumar).

- intel_pstate driver fixes and cleanups (Doug Smythies, Prarit
Bhargava, Joe Konno).

- cpufreq driver (arm_big_little, cpufreq-dt, qoriq) updates (Sudeep
Holla, Felipe Balbi, Tang Yuantian).

- assorted cleanups in cpufreq drivers and core (Shailendra Verma,
Fabian Frederick, Wang Long).

- new Device Tree bindings for representing Operating Performance
Points (Viresh Kumar).

- updates for the common clock operations support code in the PM core
(Rajendra Nayak, Geert Uytterhoeven).

- PM domains core code update (Geert Uytterhoeven).

- Intel Knights Landing support for the RAPL (Running Average Power
Limit) power capping driver (Dasaratharaman Chandramouli).

- fixes related to the floor frequency setting on Atom SoCs in the
RAPL power capping driver (Ajay Thomas).

- runtime PM framework documentation update (Ben Dooks).

- cpupower tool fix (Herton R Krzesinski)"

ACPI / PNP: Avoid conflicting resource reservations

Commit b9a5e5e18fbf "ACPI / init: Fix the ordering of
acpi_reserve_resources()" overlooked the fact that the memory
and/or I/O regions reserved by acpi_reserve_resources() may
conflict with those reserved by the PNP "system" driver.

If that conflict actually takes place, it causes the reservations
made by the "system" driver to fail while before commit b9a5e5e18fbf
all reservations made by it and by acpi_reserve_resources() would be
successful. In turn, that allows the resources that haven't been
reserved by the "system" driver to be used by others (e.g. PCI) which
sometimes leads to functional problems (up to and including boot
failures).

To fix that issue, introduce a common resource reservation routine,
acpi_reserve_region(), to be used by both acpi_reserve_resources()
and the "system" driver, that will track all resources reserved by
it and avoid making conflicting requests.
