When we build a sockaddr_storage for an IP address, clear the unused parts as
they could be used for node comparisons.I have seen this occasionally make sctp connections fail.

Level type interrupts do not need to be resent. It was also found that
some chipsets get confused in case of the resend.Mark the ioapic level type interrupts as such to avoid the resend

Commit 5a43a066b11ac2fe84cf67307f20b83bea390f83: "genirq: Allow fasteoi
handler to retrigger disabled interrupts" was erroneously applied to
handle_level_irq(). This added the irq retrigger / resend functionality
to the level irq handler.Revert the offending bits.

apply_alternatives uses memcpy() to apply alternatives. Which has the
unfortunate effect that while applying memcpy alternative to memcpy
itself it tries to overwrite itself with nops - which causes #UD fault
as it overwrites half of an instruction in copy loop, and from this
point on only possible outcome is triplefault and reboot.So let's overwrite only first two instructions of memcpy - as long as
the main memcpy loop is not in first two bytes it will work fine.Signed-off-by: Petr Vandrovec

Use DMI to:
1. enable polling (BIOS thermal events are broken)
2. disable active trip points (BIOS fan control is broken)
3. disable passive trip point (BIOS hard-codes it too low)The actual temperature reading does work,
and with the aid of polling, the critical
trip point should work too.http://bugzilla.kernel.org/show_bug.cgi?id=8842

thermal.act=-1 disables all active trip points
in all ACPI thermal zones.thermal.act=C, where C > 0, overrides all lowest temperature
active trip points in all thermal zones to C degrees Celsius.
Raising this trip-point may allow you to keep your system silent
up to a higher temperature. However, it will not allow you to
raise the lowest temperature trip point above the next higher
trip point (if there is one). Lowering this trip point may
kick in the fan sooner.Note that overriding this trip-point will disable any BIOS attempts
to implement hysteresis around the lowest temperature trip point.
This may result in the fan starting and stopping frequently
if temperature frequently crosses C.WARNING: raising trip points above the manufacturer's defaults
may cause the system to run at higher temperature and shorten
its life.Signed-off-by: Len Brown

thermal.nocrt=1 disables actions on _CRT and _HOT
ACPI thermal zone trip-points. They will be marked
as in /proc/acpi/thermal_zone/*/trip_points.There are two cases where this option is used:
1. Debugging a hot system crossing valid trip point.
If your system fan is spinning at full speed,
be sure that the vent is not clogged with dust.
Many laptops have very fine thermal fins that are easily blocked.Check that the processor fan-sink is properly seated,
has the proper thermal grease, and is really spinning.Check for fan related options in BIOS SETUP.
Sometimes there is a performance vs quiet option.
Defaults are generally the most conservative.If your fan is not spinning, yet /proc/acpi/fan/
has files in it, please file a Linux/ACPI bug.WARNING: you risk shortening the lifetime of your
hardware if you use this parameter on a hot system.
Note that this refers to all system components,
including the disk drive.2. Working around a cool system crossing critical
trip point due to erroneous temperature reading.Try again with CONFIG_HWMON=n
There is known potential for conflict between the
the hwmon sub-system and the ACPI BIOS.
If this fixes it, notify lm-sensors@lm-sensors.org
and linux-acpi@vger.kernel.orgOtherwise, file a Linux/ACPI bug, or notify
just linux-acpi@vger.kernel.org.Signed-off-by: Len Brown

"thermal.psv=-1" disables passive trip points
for all ACPI thermal zones."thermal.psv=C", where 'C' is degrees Celsius,
overrides all existing passive trip points
for all ACPI thermal zones.thermal.psv is checked at module load time,
and in response to trip-point change events.Note that if the system does not deliver thermal zone
temperature change events near the new trip-point,
then it will not be noticed. To force your custom
trip point to be noticed, you may need to enable polling:
eg. thermal.tzp=3000 invokes polling every 5 minutes.Note that once passive thermal throttling is invoked,
it has its own internal Thermal Sampling Period (_TSP),
that is unrelated to _TZP.WARNING: disabling or raising a thermal trip point
may result in increased running temperature and
shorter hardware lifetime on some systems.Signed-off-by: Len Brown

Thermal Zone Polling frequency (_TZP) is an optional ACPI object
recommending the rate that the OS should poll the associated thermal zone.If _TZP is 0, no polling should be used.
If _TZP is non-zero, then the platform recommends that
the OS poll the thermal zone at the specified rate.
The minimum period is 30 seconds.
The maximum period is 5 minutes.(note _TZP and thermal.tzp units are in deci-seconds,
so _TZP = 300 corresponds to 30 seconds)If _TZP is not present, ACPI 3.0b recommends that the
thermal zone be polled at an "OS provided default frequency".However, common industry practice is:
1. The BIOS never specifies any _TZP
2. High volume OS's from this century never poll any thermal zonesIe. The OS depends on the platform's ability to
provoke thermal events when necessary, and
the "OS provided default frequency" is "never":-)There is a proposal that ACPI 4.0 be updated to reflect
common industry practice -- ie. no _TZP, no polling.The Linux kernel already follows this practice --
thermal zones are not polled unless _TZP is present and non-zero.But thermal zone polling is useful as a workaround for systems
which have ACPI thermal control, but have an issue preventing
thermal events. Indeed, some Linux distributions still
set a non-zero thermal polling frequency for this reason.But rather than ask the user to write a polling frequency
into all the /proc/acpi/thermal_zone/*/polling_frequency
files, here we simply document and expose the already
existing module parameter to do the same at system level,
to simplify debugging those broken platforms.Note that thermal.tzp is a module-load time parameter only.

"thermal.off=1" disables all ACPI thermal support at boot time.
CONFIG_ACPI_THERMAL=n can do this at build time.
"# rmmod thermal" can do this at run time,
as long as thermal is built as a module.WARNING: On some systems, disabling ACPI thermal support
will cause the system to run hotter and reduce the
lifetime of the hardware.Signed-off-by: Len Brown
