[IPv6]: Invalid semicolon after if statement
A similar fix to netfilter from Eric Dumazet inspired me to

this kind of bugs seemed easy to automate. This is one of them
I found where it looks like this semicolon is not valid.

[IOAT]: Remove redundant struct member to avoid descriptor cache miss
The layout for struct ioat_desc_sw is non-optimal and causes an extra
cache hit for every descriptor processed. By tightening up the struct
layout and removing one item, we pull in the fields that get used in
the speedpath and get a little better performance.
Before:
-------

struct ioat_dma_descriptor * hw; /* 0 8
*/
struct list_head node; /* 8 16
*/
int tx_cnt; /* 24 4

dma_addr_t src; /* 32 8
*/
__u32 src_len; /* 40 4
*/
/* XXX 4 bytes hole, try to pack */
dma_addr_t dst; /* 48 8
*/
__u32 dst_len; /* 56 4
*/
/* XXX 4 bytes hole, try to pack */
/* --- cacheline 1 boundary (64 bytes) --- */
struct dma_async_tx_descriptor async_tx; /* 64 144

/* --- cacheline 3 boundary (192 bytes) was 16 bytes ago --- */
/* size: 208, cachelines: 4 */
/* sum members: 196, holes: 3, sum holes: 12 */

Due to a mix up between the jdata attribute and inherit jdata attribute
it has not been possible to set the inherit jdata attribute on
directories. This is now fixed and the ioctl will report the inherit

This patch seems to fix the problem described in bugzilla bug 246114.
It was written by Steve Whitehouse with some tweaking by me.
The code was looping in the relatively new section of code designed to
search for and reuse unlinked inodes. In cases where it was finding an
appropriate inode to reuse, it was looping around and finding the same
block over and over because a "<=" check should have been a "<" when
comparing the goal block to the last unlinked block found.

[GFS2] soft lockup detected in databuf_lo_before_commit
This is part 2 of the patch for bug #245832, part 1 of which is already
in the git tree.
The problem was that sdp->sd_log_num_databuf was not always being
protected by the gfs2_log_lock spinlock, but the sd_log_le_databuf
(which it is supposed to reflect) was protected. That meant there
was a timing window during which gfs2_log_flush called
databuf_lo_before_commit and the count didn't match what was
really on the linked list in that window. So when it ran out of
items on the linked list, it decremented total_dbuf from 0 to -1 and
thus never left the "while(total_dbuf)" loop.
The solution is to protect the variable sdp->sd_log_num_databuf so
that the value will always match the contents of the linked list,
and therefore the number will never go negative, and therefore, the
loop will be exited properly.

Fix a long standing bug where a blocking callback would be missed
when there's a granted lock in PR mode and waiting locks in both
PR and CW modes (and the PR lock was added to the waiting queue

of the modes to determine if a blocking callback was required, but in
the one case of PR and CW, the lower valued CW mode blocks the higher

http://bugzilla.kernel.org/show_bug.cgi?id=8797 shows that the

For example, if you bond devices with NETIF_F_HW_CSUM and
NETIF_F_IP_CSUM you'll end up with a bonding device that
has neither flag set. If both have TSO then this produces
an illegal combination.
The bridge device on the other hand has the correct code to
deal with this.
In fact, the same code can be used for both. So this patch
moves that logic into net/core/dev.c and uses it for both
bonding and bridging.

The following patch fixes the above problem.
From: Andrew Morton <akpm@linux-foundation.org>
Davem said (in February!):
Well, first of all the change in question is not in 2.4.x either. I just
checked the current 2.4.x GIT tree and the test is exactly:
if (ic_myaddr == INADDR_NONE ||
#ifdef CONFIG_ROOT_NFS
(MAJOR(ROOT_DEV) == UNNAMED_MAJOR
&& root_server_addr == INADDR_NONE
&& ic_servaddr == INADDR_NONE) ||
#endif
ic_first_dev->next) {
which matches 2.6.x
I even checked 2.4.x when it was branched for 2.5.x and the test was the
same at the point in time too.
Looking at the proposed change a bit it appears that it is probably
correct, as it's trying to check that ROOT_DEV is nfs root. But if it is
correct then the UNNAMED_MAJOR comparison in the same code block should be
removed as it becomes superfluous.
I'm happy to apply this patch with that modification made.

Do not replace whole memcpy in apply alternatives
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.

ACPI: thermal: add DMI hooks to handle AOpen's broken Award BIOS
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.

ACPI: thermal: create "thermal.act=" to disable or override active trip point
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.

ACPI: thermal: create "thermal.nocrt" to disable critical actions
thermal.nocrt=1 disables actions on _CRT and _HOT
ACPI thermal zone trip-points. They will be marked
as <disabled> 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.org
Otherwise, file a Linux/ACPI bug, or notify
just linux-acpi@vger.kernel.org.

ACPI: thermal: create "thermal.psv=" to override passive trip points
"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.

ACPI: thermal: expose "thermal.tzp=" to set global polling frequency
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 zones
Ie. 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.
