When either rx_buf or tx_buf is not being used, i.e. for plain read- or
write operations, the atmel_spi uses a fixed-size DMA buffer instead. If
the transfer is longer than the size of this buffer, it is split into
multiple DMA transfers.
When the transfer is split like this, the atmel_spi driver ends up using
the same DMA address again and again even for the buffer that came from the
user, which is of course wrong. Fix this by adding the number of bytes
already transferred to the DMA address so that the data ends up in the
right place.
Thanks to Wu Xuan for discovering this bug.

With "modprobe sbp2 long_ieee1394_id=y", the format of

0001041010004beb:0:0 to 0001041010004beb:00042c:0000.
The longer format fully conforms to object identifier sizes as per
SAM(-2...4) and reflects what the SAM target port identifier is meant to
contain: A Discovery ID allegedly specified by ISO/IEC 13213:1994 ---
however there is no such thing; the authors of SAM probably meant
Directory ID). Especially target nodes with multiple dynamically added
targets may use Directory IDs to persistently identify target ports.
The new format is independent of implementation details of nodemgr.
Thus the same ieee1394_id attribute format can be implemented in the new
firewire stack.
The ieee1394_id is typically used to create persistently named links in
/dev/disk/by-id.

The initial version of the thinkpad-acpi sysfs interface (not yet released
in any stable mainline kernel) made liberal use of named sysfs groups, in
order to get the attributes more organized.
This proved to be a really bad design decision. Maybe if attribute groups
were as flexible as a real directory, and if binary attributes were not
second-class citizens, the idea of subdirs and named groups would not have
been so bad.
This patch makes all the thinkpad-acpi sysfs groups anonymous (thus
removing the subdirs), adds the former group names as a prefix (so that
hotkey/enable becomes hotkey_enable for example), and updates the
documentation.
These changes will make the thinkpad-acpi sysfs ABI a lot easier to
maintain.

_OSI("Linux") is like _OS("Linux"), it is ill-defined and
virtually no BIOS vendors test interaction with it.
As a result, it can do more damage than good because
it causes the BIOS to follow un-tested paths.
Recently, several machines have turned up that erroneously
test this string in a way which causes them to _not_ test other
compatibility strings, including the ZI9 and Toshiba.
So it appears that this bad code has made it into
a BIOS vendor's reference BIOS.
Linux has no choice but to stop advertising compatibility
with _OSI string "Linux" - as there are an unbounded
number of possible incompatibilities going forward.
But some BIOSes have already shipped which do use it
for things like conditionally re-enabling video on resume
from S3. (Too bad they didn't do that unconditionally)
Add special case code for _OSI(Linux)
Squawk to dmesg if _OSI(Linux) is requested
Add DMI list both to enable and disable _OSI(Linux)
But for now, keep the default enabled via
#define OSI_LINUX_ENABLED.

commit 518b1646 ("IPoIB/cm: Fix SRQ WR leak") introduced a severe
performance regression on Mellanox cards, because keeping a QP in the
error state for extended periods of time moves hardware to the slow
path (until the QP is destroyed). For example, MPI latency goes from
~3 usecs to ~7 usecs.
Fix this by posting a send WR on one of the QPs that are being
flushed, instead of using a separate drain QP that is kept in the
error state.

identically if a QP is using an SRQ. But for Tavor hardware, send

Fix by following the WQE chain for all send CQEs even for non-SRQ QPs.

This patch (as912) replaces a couple of calls to flush_workqueue()
with cancel_sync_work() and cancel_rearming_delayed_work(). Using a
more directed approach allows us to avoid some nasty deadlocks. The
prime example occurs when a first-level device (the parent is a root
hub) is removed while at the same time the root hub gets a remote
wakeup request. khubd would try to flush the autosuspend workqueue
while holding the root-hub's lock, and the remote-wakeup workqueue
routine would be waiting to lock the root hub.
The patch also reorganizes the power management portion of
usb_disconnect(), separating it out into its own routine. The
autosuspend workqueue entry is cancelled immediately instead of
waiting for the device's release routine. In addition,
synchronization with the autosuspend thread is carried out even for
root hubs (an oversight in the original code).

When hostap_tx_encrypt() tries to allocate enough headroom and
tailroom for ieee80211 encryption, it only makes enough room for the
"mpdu" phase of the operation, but forgets about the "msdu" phase.
(For TKIP, these two phases require, respectively, 4 and 8 bytes of
tailroom, per the "ieee80211_crypt_tkip" structure at the bottom of
net/ieee80211/ieee80211_crypt_tkip.c.)

The Linux kernel ignored the PROM's serial settings (115200,n,8,1 in
my case). This was because mode_prop remained "ttyX-mode" (expected:
"ttya-mode") due to the constness of string literals when used with
"char *". Since there is no "ttyX-mode" property in the PROM, Linux
always used the default 9600.

packet->data_size was set to any useful value. It got broken when
packet->allocated_data_size got introduced, as hpsb_alloc_packet does
not set packet->data_size anymore. (Regression in 2.6.22-rc1)

This adds a real parent device to eth1394's ethX device like in Linux
2.6.20 and older. However, due to unfinished conversion of the ieee1394
away from class_device, we now refer to the FireWire controller's PCI
device as the parent, not to the ieee1394 driver's fw-host device.
Having a real parent device instead of a virtual one allows udev scripts
to distinguish eth1394 interfaces from networking bridges, bondings and
the likes.

When eth1394 was unable to acquire a transaction label, it just dropped
outgoing packets without attempt to resend them later.
The transmit queue is now halted if no tlabel is available to
->hard_start_xmit(). A workqueue job is then scheduled to catch the
moment when ieee1394 recycled the next lot of tlabels.
