Thomas Jarosch reported IPsec TCP stalls when a PMTU event occurs.
In fact the problem was completely unrelated to IPsec. The bug is
also reproducible if you just disable TSO/GSO.
The problem is that when the MSS goes down, existing queued packet
on the TX queue that have not been transmitted yet all look like
TSO packets and get treated as such.
This then triggers a bug where tcp_mss_split_point tells us to
generate a zero-sized packet on the TX queue. Once that happens
we're screwed because the zero-sized packet can never be removed
by ACKs.
Fixes: 1485348d24 ("tcp: Apply device TSO segment limit earlier")

This reverts commit 24a0aa212e.
It's causing severe userspace breakage. Namely, all the utilities from
wireless-utils which are relying on CONFIG_WEXT (which means tools like
'iwconfig', 'iwlist', etc) are not working anymore. There is a 'iw'
utility in newer wireless-tools, which is supposed to be a replacement
for all the "deprecated" binaries, but it's far away from being
massively adopted.
Please see [1] for example of the userspace breakage this is causing.
In addition to that, Larry Finger reports [2] that this patch is also
causing ipw2200 driver being impossible to build.
To me this clearly shows that CONFIG_WEXT is far, far away from being
"deprecated enough" to be removed.

Commit ac61d19559 (scsi: set correct completion code in
scsi_send_eh_cmnd()) introduced a bug. It changed the stored return
value from a queuecommand call, but it didn't take into account that
the return value was used again later on. This patch fixes the bug by
changing the later usage.
There is a big comment in the middle of scsi_send_eh_cmnd() which
does a good job of explaining how the routine works. But it mentions
a "rtn = FAILURE" value that doesn't exist in the code. This patch
adjusts the code to match the comment (I assume the comment is right
and the code is wrong).
This fixes Bugzilla #88341.

ASoC: Fixes for v3.19
A few fixes for v3.19, a few driver specifics and one core fix which
fixes a boot crash on OMAP if deferred probing kicks in due to
attempting to modify static data.
Currently we enable Exynos devices in the multi v7 defconfig, however, when
testing on my ODROID-U3, I noticed that USB was not working. Enabling this
option causes USB to work, which enables networking support as well since the
ODROID-U3 has networking on the USB bus.
[arnd] Support for odroid-u3 was added in 3.10, so it would be nice to
backport this fix at least that far.

Unfortunately, while commit 4a928436 ("audit: correctly record file
names with different path name types") fixed a problem where we were
not recording filenames, it created a new problem by attempting to use
these file names after they had been freed. This patch resolves the
issue by creating a copy of the filename which the audit subsystem
frees after it is done with the string.
At some point it would be nice to resolve this issue with refcounts,
or something similar, instead of having to allocate/copy strings, but
that is almost surely beyond the scope of a -rcX patch so we'll defer
that for later. On the plus side, only audit users should be impacted
by the string copying.

When I/O is aborted by mid-layer, fnic FW will complete the I/O before
completing the abort task. In some cases abort request is completed before
the I/O, which could lead to inconsistent driver and firmware states.
In this case firmware reset would clear the inconsistent state.

7985090aa0 changed the discard heuristics to give preference to the
WRITE SAME commands that (unlike UNMAP) guarantee deterministic results.
Ming Lei discovered that QEMU SCSI's WRITE SAME implementation
internally relied on limits that were only communicated for the UNMAP
case. And therefore discard commands backed by WRITE SAME would fail.
Tweak the heuristics so we still pick UNMAP in the LBPRZ=0 case and only
prefer the WRITE SAME variants if the device has the LBPRZ flag set.

The Rockchip pinctrl driver was only implementing the "mask" and
"unmask" operations though the hardware actually has two distinct
things: enable/disable and mask/unmask. It was implementing the
"mask" operations as a hardware enable/disable and always leaving all
interrupts unmasked.
I believe that the old system had some downsides, specifically:
- (Untested) if an interrupt went off while interrupts were "masked"
it would be lost. Now it will be kept track of.
- If someone wanted to change an interrupt back into a GPIO (is such a
thing sensible?) by calling irq_disable() it wouldn't actually take
effect. That's because Linux does some extra optimizations when
there's no true "disable" function: it does a lazy mask.
Let's actually implement enable/disable/mask/unmask properly.

The rockchip pinctrl driver was using irq_gc_set_wake() as its
implementation of irq_set_wake() but was totally ignoring everything
that irq_gc_set_wake() did (which is to upkeep gc->wake_active).
Let's fix that by setting gc->wake_active as GPIO_INTEN at suspend
time and restoring GPIO_INTEN at resume time.
NOTE a few quirks when thinking about this patch:
- Rockchip pinctrl hardware supports both "disable/enable" and
"mask/unmask". Right now we only use "disable/enable" and present
those to Linux as "mask/unmask". This should be OK because
enable/disable is optional and Linux will implement it in terms of
mask/unmask. At the moment we always tell hardware all interrupts
are unmasked (the boot default).
- At suspend time Linux tries to call "disable" on all interrupts and
also enables wakeup on all wakeup interrupts. One would think that
since "disable" is implemented as "mask" when "disable" isn't
provided and that since we were ignoring gc->wake_active that
nothing would have woken us up. That's not the case since Linux
"optimizes" things and just leaves interrutps unmasked, assuming it
could mask them later when they go off. That meant that at suspend
time all interrupts were actually being left enabled.
With this patch random non-wakeup interrupts no longer wake the system
up. Wakeup interrupts still wake the system up.

After the commit ef691ff48b (OMAPDSS: DT: Get source endpoint by
matching reg-id) we look for the SDI output using the port number.
However, the SDI driver doesn't set the port number, which causes the
SDI display to not initialize.
Fix this by setting the SDI port number to 1. We use a hardcoded value,
as SDI was used only on OMAP3 and it's always port number 1 there.

fb_deferred_io_fsync() returns the value of schedule_delayed_work() as
an error code, but schedule_delayed_work() does not return an error. It
returns true/false depending on whether the work was already queued.
