Bartlomiej Zolnierkiewicz ec79be2687 PM / ACPI: HP G7000 Notebook needs a SCI_EN resume quirk
This fixes regression (battery "vanishing" on resume) introduced by
commit d0c71fe7eb ("ACPI Suspend: Enable
ACPI during resume if SCI_EN is not set") and also the issue with
the "screaming" IRQ 9.

Rafael J. Wysocki 6a7c7eaf71 PM/Suspend: Introduce two new platform callbacks to avoid breakage
Commit 900af0d973 (PM: Change suspend
code ordering) changed the ordering of suspend code in such a way
that the platform .prepare() callback is now executed after the
device drivers' late suspend callbacks have run.  Unfortunately, this
turns out to break ARM platforms that need to talk via I2C to power
control devices during the .prepare() callback.

For this reason introduce two new platform suspend callbacks,
.prepare_late() and .wake(), that will be called just prior to
disabling non-boot CPUs and right after bringing them back on line,
respectively, and use them instead of .prepare() and .finish() for
ACPI suspend.  Make the PM core execute the .prepare() and .finish()
platform suspend callbacks where they were executed previously (that
is, right after calling the regular suspend methods provided by
device drivers and right before executing their regular resume
methods, respectively).

It is not necessary to make analogous changes to the hibernation
code and data structures at the moment, because they are only used
by ACPI platforms.

Len Brown 96f15efcea ACPI: Disable _GTS and _BFS support by default
Executing BIOS code paths not exercised by Windows
tends to get Linux into trouble.

However, if a system does benefit from _GTS or _BFS,
acpi.gts=1 an acpi.bfs=1 are now available to enable them.

Bjorn Helgaas e60cc7a6f0 ACPI: move private declarations to internal.h
A number of things that shouldn't be exposed outside the ACPI core
were declared in include/acpi/acpi_drivers.h, where anybody can
see them.  This patch moves those declarations to a new "internal.h"
inside drivers/acpi.

Andy Whitcroft a140449584 suspend: switch the Asus Pundit P1-AH2 to old ACPI sleep ordering
Switch the Asus Pundit P1-AH2 (M2N8L motherboard) to the old ACPI 1.0
sleep ordering by default.  Without this it will not suspend/resume
correctly.
