The -rt patch triggered a lockdep warning in the amba serial drivers, which never
shows up on UP kernels. On SMP systems this would trigger as well.
Release the port lock before calling tty_flip_buffer_push() and reacquire it after
the call. This matches the code in the 8250 serial driver.

_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.
This fixes bug <https://bugs.openfabrics.org/show_bug.cgi?id=636>,

Sasha Mikheev at Voltaire.

mthca_free_err_wqe() currently treats both send and receive CQEs
identically if a QP is using an SRQ. But for Tavor hardware, send
CQEs with error can be chained together even if the RQ is part of SRQ,
so we may miss some CQEs.
Fix by following the WQE chain for all send CQEs even for non-SRQ QPs.
This fixes crashes in IPoIB CM:

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).

"char *". Since there is no "ttyX-mode" property in the PROM, Linux
always used the default 9600.

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.

The omap_uwire controller driver handles SPI_CPHA incorrectly;
It should mean:

If a raid0 has a component device larger than 4TB, and is accessed on a 32bit
machines, then as 'chunk' is unsigned long,
chunk << chunksize_bits
can overflow (this can be as high as the size of the device in KB). chunk
itself will not overflow (without triggering a BUG).
So change 'chunk' to be 'sector_t, and get rid of the 'BUG' as it becomes
impossible to hit.

in the commit, ads784x samples the data on the rising edge. SPI mode 1
samples on the falling edge [2] though.
The root cause of this is a bug in the omap_uwire code, which treats
CPHA=1 incorrectly; so these two bugs cancel each other out on one
of the main regression test platforms for this driver.

Every so often, the driver will call asd_clear_nexus to clean out a task.
It is supposed to be the case that the CLEAR NEXUS does not go on the done
list until after the task itself has been put on the done list, but for
some reason this doesn't always happen. Thus, the
wait_for_completion_timeout call times out, and we return success. This
makes libsas free the task even though the task hasn't completed, leading
to a BUG_ON message from aic94xx_hwi.c around line 341. We should return
failure from asd_clear_nexus so that libsas tries again; at a bare minimum
it shouldn't be freeing active tasks. I _think_ this will fix one of
the SCB timeout crash problems (though I've not been able to reproduce
it lately...)

Under some conditions associated with the unclean transition to kdump,
the aacraid adapters will view the array as foreign and not export it to
prevent access and data manipulation. The solution is to submit a commit
configuration to export the devices since this is a expected behavior
when transitioning to a kdump kernel.
This patch adds the aacraid.reset_devices flag and when either this or
the global reset_devices flag is set, ensures that a commit config is
issued and extends the startup_timeout if it is set less than 5 minutes.

Prevent legacy drivers from issuing uevents for device creation/removal,
so that userspace can't cause modprobing loops for them. This became a
problem for some legacy PC drivers. I can't easily see it becoming an
issue with I2C legacy drivers, but consistency-in-paranoia seems likely
to be a good thing here. For usable i2c-level driver model uevents, just
switch to a new-style driver.

Removing the call to netif_poll_enable in e1000_open should fix this issue,
the only other call to netif_poll_enable is in e1000_up() which is only
reached after a device reset or resume.

The IB CM uses an idr for local id allocations, with a running counter
as start_id. This fails to generate distinct ids if
1. An id is constantly created and destroyed
2. A chunk of ids just beyond the current next_id value is occupied
This in turn leads to an increased chance of connection request being
mis-detected as a duplicate, sometimes for several retries, until
next_id gets past the block of allocated ids. This has been observed
in practice.
As a fix, remember the last id allocated and start immediately above it.
This also fixes a problem with the old code, where next_id might
overflow and become negative.

SRQ WR leakage has been observed with IPoIB/CM: e.g. flipping ports on
and off will, with time, leak out all WRs and then all connections
will start getting RNR NAKs. Fix this in the way suggested by spec:
move the QP being destroyed to the error state, wait for "Last WQE
Reached" event and then post WR on a "drain QP" connected to the same
CQ. Once we observe a completion on the drain QP, it's safe to call
ib_destroy_qp.
