A bug was reported that the semtimedop() system call was always
failing eith ENOSYS.
Since SEMCTL is defined as 3, and SEMTIMEDOP is defined as 4,
the comparison "call <= SEMCTL" will always prevent SEMTIMEDOP
from getting through to the semaphore ops switch statement.
This is corrected by changing the comparison to "call <= SEMTIMEDOP".

Commit 6ce29b0e2a04 ("gianfar: Avoid unnecessary reg accesses in adjust_link()")
eliminates unnecessary calls to adjust_link for phy devices which don't support
interrupts and need polling. As part of that work, the 'new_state' local flag,
which was used to reduce logging noise on the console, was eliminated.
Unfortunately, that means that a 'Link is Down' log message will now be
issued continuously if a link is configured as UP, the link state is down,
and the associated phy requires polling. This occurs because priv->oldduplex
is -1 in this case, which always differs from phydev->duplex. In addition,
phydev->speed may also differ from priv->oldspeed. gfar_update_link_state()
is therefore called each time a phy is polled, even if the link state did not
change.

The DDRSDR controller fails miserably to put LPDDR1 memories in
self-refresh. Force the controller to think it has DDR2 memories
during the self-refresh period, as the DDR2 self-refresh spec is
equivalent to LPDDR1, and is correctly implemented in the
controller.

When invalidating the page cache for a regular file, we want to first
sync all dirty data to disk and then call invalidate_inode_pages2().
The latter relies on nfs_launder_page() and nfs_release_page() to deal
respectively with dirty pages, and unstable written pages.
When commit 9590544694bec ("NFS: avoid deadlocks with loop-back mounted
NFS filesystems.") changed the behaviour of nfs_release_page(), then it
made it possible for invalidate_inode_pages2() to fail with an EBUSY.
Unfortunately, that error is then propagated back to read().
Let's therefore work around the problem for now by protecting the call
to sync the data and invalidate_inode_pages2() so that they are atomic
w.r.t. the addition of new writes.
Later on, we can revisit whether or not we still need nfs_launder_page()
and nfs_release_page().

This is a tricky story of the new atomic state handling and the legacy
code fighting over each another. The bug at hand is an underrun of the
framebuffer reference with subsequent hilarity caused by the load
detect code. Which is peculiar since the the exact same code works
fine as the implementation of the legacy setcrtc ioctl.
Let's look at the ingredients:
- Currently our code is a crazy mix of legacy modeset interfaces to
set the parameters and half-baked atomic state tracking underneath.
While this transition is going we're using the transitional plane
helpers to update the atomic side (drm_plane_helper_disable/update
and friends), i.e. plane->state->fb. Since the state structure owns
the fb those functions take care of that themselves.
The legacy state (specifically crtc->primary->fb) is still managed
by the old code (and mostly by the drm core), with the fb reference
counting done by callers (core drm for the ioctl or the i915 load
detect code). The relevant commit is

drm/i915: Move to atomic plane helpers (v9)
- drm_plane_helper_disable has special code to handle multiple calls
in a row - it checks plane->crtc == NULL and bails out. This is to
match the proper atomic implementation which needs the crtc to get
at the implied locking context atomic updates always need. See

drm/plane-helper: transitional atomic plane helpers
- The universal plane code split out the implicit primary plane from
the CRTC into it's own full-blown drm_plane object. As part of that
the setcrtc ioctl (which updated both the crtc mode and primary
plane) learned to set crtc->primary->crtc on modeset to make sure
the plane->crtc assignments statate up to date in

drm: Add drm_crtc_init_with_planes() (v2)
Unfortunately we've forgotten to update the load detect code. Which
wasn't a problem since the load detect modeset is temporary and
always undone before we drop the locks.
- Finally there is a organically grown history (i.e. don't ask) around
who sets the legacy plane->fb for the various driver entry points.
Originally updating that was the drivers duty, but for almost all
places we've moved that (plus updating the refcounts) into the core.
Again the exception is the load detect code.
Taking all together the following happens:
- The load detect code doesn't set crtc->primary->crtc. This is only
really an issue on crtcs never before used or when userspace
explicitly disabled the primary plane.
- The plane helper glue code short-circuits because of that and leaves
a non-NULL fb behind in plane->state->fb and plane->fb. The state
fb isn't a real problem (it's properly refcounted on its own), it's
just the canary.
- Load detect code drops the reference for that fb, but doesn't set
plane->fb = NULL. This is ok since it's still living in that old
world where drivers had to clear the pointer but the core/callers
handled the refcounting.
- On the next modeset the drm core notices plane->fb and takes care of
refcounting it properly by doing another unref. This drops the
refcount to zero, leaving state->plane now pointing at freed memory.
- intel_plane_duplicate_state still assume it owns a reference to that
very state->fb and bad things start to happen.
Fix this all by applying the same duct-tape as for the legacy setcrtc
ioctl code and set crtc->primary->crtc properly.

Routine rtl_is_special_data() is supposed to identify packets that need to
use a low bit rate so that the probability of successful transmission is
high. The current version has a bug that causes all IPv6 packets to be
labelled as special, with a corresponding low rate of transmission. A
complete fix will be quite intrusive, but until that is available, all
IPv6 packets are identified as regular.
This patch also removes a magic number.

Some APs experience problems when working with
U-APSD. Decreasing the probability of that
happening by using legacy mode for all ACs but VO
isn't enough.
Cisco 4410N originally forced us to enable VO by
default only because it treated non-VO ACs as
legacy.
However some APs (notably Netgear R7000) silently
reclassify packets to different ACs. Since u-APSD
ACs require trigger frames for frame retrieval
clients would never see some frames (e.g. ARP
responses) or would fetch them accidentally after
a long time.
It makes little sense to enable u-APSD queues by
default because it needs userspace applications to
be aware of it to actually take advantage of the
possible additional powersavings. Implicitly
depending on driver autotrigger frame support
doesn't make much sense.

eCryptfs can't be aware of what to expect when after passing an
arbitrary ioctl command through to the lower filesystem. The ioctl
command may trigger an action in the lower filesystem that is
incompatible with eCryptfs.
One specific example is when one attempts to use the Btrfs clone
ioctl command when the source file is in the Btrfs filesystem that
eCryptfs is mounted on top of and the destination fd is from a new file
created in the eCryptfs mount. The ioctl syscall incorrectly returns
success because the command is passed down to Btrfs which thinks that it
was able to do the clone operation. However, the result is an empty
eCryptfs file.
This patch allows the trim, {g,s}etflags, and {g,s}etversion ioctl
commands through and then copies up the inode metadata from the lower
inode to the eCryptfs inode to catch any changes made to the lower
inode's metadata. Those five ioctl commands are mostly common across all
filesystems but the whitelist may need to be further pruned in the
future.
