commit 6e6c25283dff866308c87b49434c7dbad4774cc0 upstream.
kobject_init_and_add() takes reference even when it fails.
Thus, when kobject_init_and_add() returns an error,
kobject_put() must be called to properly clean up the kobject.

[ Upstream commit 0f27cff8597d86f881ea8274b49b63b678c14a3c ]
The acpi_mask_gpe= kernel parameter documentation states that the range
of mask is 128 GPEs (0x00 to 0x7F). The acpi_masked_gpes mask is a u64 so
only 64 GPEs (0x00 to 0x3F) can really be masked.
Use a bitmap of size 0xFF instead of a u64 for the GPE mask so 256
GPEs can be masked.

[ Upstream commit 9c4aa1eecb48cfac18ed5e3aca9d9ae58fbafc11 ]
Sometimes, the users may require a quirk to be provided from ACPI subsystem
core to prevent a GPE from flooding.
Normally, if a GPE cannot be dispatched, ACPICA core automatically prevents
the GPE from firing. But there are cases the GPE is dispatched by _Lxx/_Exx
provided via AML table, and OSPM is lacking of the knowledge to get
_Lxx/_Exx correctly executed to handle the GPE, thus the GPE flooding may
still occur.
The existing quirk mechanism can be enabled/disabled using the following
commands to prevent such kind of GPE flooding during runtime:
# echo mask > /sys/firmware/acpi/interrupts/gpe00
# echo unmask > /sys/firmware/acpi/interrupts/gpe00
To avoid GPE flooding during boot, we need a boot stage mechanism.
This patch provides such a boot stage quirk mechanism to stop this kind of
GPE flooding. This patch doesn't fix any feature gap but since the new
feature gaps could be found in the future endlessly, and can disappear if
the feature gaps are filled, providing a boot parameter rather than a DMI
table should suffice.

This patch cleans up sysfs table signature handling code:
1. Convert the signature handling code to use the ACPICA APIs to
benefit from the future improvements of the APIs.
2. Add 'filename' attribute in order to handle both BE/LE name tags.
3. Add instance check in order to avoid the possible buffer overflow
related to the table file name.

OEM tables can be installed via RSDT/XSDT, in this case, they have already
been created under /sys/firmware/acpi/tables.
For this kind of tables, normally LoadTable opcode will be executed to load
them. If LoadTable opcode is executed after acpi_sysfs_init(),
acpi_sysfs_table_handler() will be invoked, thus a redundant table file
will be created under /sys/firmware/acpi/tables/dynamic. Then running
"acpidump" on such platform results in an error, complaining blank empty
table (see Link 1 below).
The bug can be reproduced by customizing an OEM1 table, allowing it to be
overridden via 'table_sigs' (drivers/acpi/tables.c), adding the following
code to the customized DSDT to load it:
Name (OEMH, Zero)
Name (OEMF, One)
If (LEqual (OEMF, One)) {
Store (LoadTable ("OEM1", "Intel", "Test"), OEMH)
Store (Zero, OEMF)
}
In order to make sure that the OEM1 table is installed after
acpi_sysfs_init(), acpi_sysfs_init() can be moved before invoking
acpi_load_tables(). Then the following command execution result can be
seen:
# acpidump > acpidump.txt
Could not read table header: /sysfs/firmware/acpi/tables/dynamic/OEM12
Could not get ACPI table at index 17, AE_BAD_HEADER

Now GPE can be masked via the new acpi_mask_gpe() API and this patch
modifies /sys/firmware/acpi/interrupts/gpexx to use this new facility.
Writes "mask/unmask" to this file now invokes acpi_mask_gpe().
Reads from this file now returns new "EN/STS" when the corresponding GPE
hardware register's EN/STS bits are flagged, and new "masked/unmasked"
attribute to indicate the status of the masking mechanism.

Add support for ACPI reconfiguration notifiers to allow subsystems
to react to changes in the ACPI tables that happen after the initial
enumeration. This is similar with the way dynamic device tree
notifications work.
The reconfigure notifications supported for now are device add and
device remove.
Since ACPICA allows only one table notification handler, this patch
makes the table notifier function generic and moves it out of the
sysfs specific code.

This patch updates the method tracing facility as the acpi_debug_trace()
API has been updated to allow it to trace AML interpreter execution, the
meanings and the usages of the API parameters are changed due to the
updates.
The new API:
1. Uses ACPI_TRACE_ENABLED flag to indicate the enabling of the tracer;
2. Allows tracer still can be enabled when method name is not specified so
that the AML interpreter execution can be traced without knowing the
method name, which is useful for kernel boot tracing;
3. Supports arbitrary full path name, it doesn't need to be a name related
to an entrance of acpi_evaluate_object().
Note that the sysfs parameters are also updated so that when reading the
attribute files, ACPICA internal settings are returned.
In order to make the sysfs parameters (acpi.trace_state) available during
boot, this patch adds code to bypass ACPICA semaphore/mutex invocations
when acpi mutex utilities haven't been initialized.
This patch doesn't update documentation of method tracing facility, it will
be updated by further patches.

is set if the event/gpe currently has a handler associated with it.
This patch contains the code to rename ACPI_EVENT_FLAG_HANDLE to

The use of "bool" is not safe for ACPICA code where it is originally using
a "BOOLEAN" defined as "unsigned char".
This patch removes the only "bool" usage from kernel source tree to reduce
the source code differences between Linux and ACPICA upstream.

Replace direct inclusions of <acpi/acpi.h>, <acpi/acpi_bus.h> and
<acpi/acpi_drivers.h>, which are incorrect, with <linux/acpi.h>
inclusions and remove some inclusions of those files that aren't
necessary.
First of all, <acpi/acpi.h>, <acpi/acpi_bus.h> and <acpi/acpi_drivers.h>
should not be included directly from any files that are built for
CONFIG_ACPI unset, because that generally leads to build warnings about
undefined symbols in !CONFIG_ACPI builds. For CONFIG_ACPI set,
<linux/acpi.h> includes those files and for CONFIG_ACPI unset it
provides stub ACPI symbols to be used in that case.
Second, there are ordering dependencies between those files that always
have to be met. Namely, it is required that <acpi/acpi_bus.h> be included
prior to <acpi/acpi_drivers.h> so that the acpi_pci_root declarations the
latter depends on are always there. And <acpi/acpi.h> which provides
basic ACPICA type declarations should always be included prior to any other
ACPI headers in CONFIG_ACPI builds. That also is taken care of including
<linux/acpi.h> as appropriate.

When executing on an ACPI Hardware Reduced hardware, all the ACPI
tables are not exposed in sysfs due to the fact that FACS is
silently ignored by the kernel in the ACPI hardware reduced mode
and, moreover, the acpi_tables_sysfs_init() ACPI table walk
is buggy and stops too soon.
The acpi_tables_sysfs_init() function should rely on the acpi_status
return value from acpi_get_table_by_index() to decide whether or not
to stop the iteration (the walk should only be terminated when that
value is AE_BAD_PARAMETER). This way, when running in an ACPI Harware
Reduced environment (where the FACS table is silently ignored by the
kernel) or if some ACPI tables are not correctly memory mapped or
have bad checksums, it will still walk through the remaining tables
that may be correct.

According to the design, GPE sysfs attributes should accept "disable",
"enable", "clear" and integer numbers as params. Current code checks
"disable", "enable" and "clear" first. If the param doesn't match,
pass it to strtoul() as a string representing an integer number and
assign the return value to the given GPE count. It is missing the check
of whether or not the param really represents an integer number and
strtoul() will return 0 if the string is not a number. This causes any
params except for "enable", "disable", "clear" and a number to make the
GPE count become 0. This patch is to use kstrtoul() to replace strtoul()
and check the return value. If the convertion is successful, use as the
new GPE count. If not, return an error.

Fix various weird constructions of strncpy(dst, src, strlen(src)).
Length limits should be about the space available in the destination,
not repurposed as a method to either always include or always exclude a
trailing NULL byte. Either the NULL should always be copied (using
strlcpy), or it should not be copied (using something like memcpy).
Readable code should not depend on the weird behavior of strncpy when it
hits the length limit. Better to avoid the anti-pattern entirely.

Modify the generic ACPI hotplug code to be able to check if devices
scheduled for hot-removal may be gracefully removed from the system
using the device offline/online mechanism introduced previously.
Namely, make acpi_scan_hot_remove() handling device hot-removal call
device_offline() for all physical companions of the ACPI device nodes
involved in the operation and check the results. If any of the
device_offline() calls fails, the function will not progress to the
removal phase (which cannot be aborted), unless its (new) force
argument is set (in case of a failing offline it will put the devices
offlined by it back online).
In support of 'forced' device hot-removal, add a new sysfs attribute
'force_remove' that will reside under /sys/firmware/acpi/hotplug/.

Introduce user space interface for manipulating hotplug profiles
associated with ACPI scan handlers.
The interface consists of sysfs directories under
/sys/firmware/acpi/hotplug/, one for each hotplug profile, containing
an attribute allowing user space to manipulate the enabled field of
the corresponding profile. Namely, switching the enabled attribute
from '0' to '1' will cause the common hotplug notify handler to be
installed for all ACPI namespace objects representing devices matching
the scan handler associated with the given hotplug profile (and
analogously for the converse switch).
Drivers willing to use the new user space interface should add their
ACPI scan handlers with the help of new funtion
acpi_scan_add_handler_with_hotplug().

There are a lot userspace approaches to detect the usage of the
platform (laptop, workstation, server, ...) and adjust kernel tunables
accordingly (io/process scheduler, power management, ...).
These approaches need constant maintaining and are ugly to implement
(detect PCMCIA controller -> laptop,
does not work on recent systems anymore, ...)
On ACPI systems there is an easy and reliable way (if implemented
in BIOS and most recent platforms have this value set).
-> export it to userspace.
