This is leftover stuff from my previous doc round which I kinda wanted
to do but didn't yet due to rebase hell.
The modeset helpers and the probing helpers a independent and e.g.
i915 uses the probing stuff but has its own modeset infrastructure. It
hence makes to split this up. While at it add a DOC: comment for the
probing libraray.
It would be rather neat to pull some of the DocBook documenting these
two helpers into in-line DOC: comments. But unfortunately kerneldoc
doesn't support markdown or something similar to make nice-looking
documentation, so the current state is better.

After thinking about this topic a bit more I've reached the conclusion
that implementing this doesn't make sense:
- The locking is all wrong: set_config(NULL) will also unlink encoders
and connectors, but those links are protected with the mode_config
mutex. In the ->disable_plane callback we only hold all modeset
locks, but eventually we want to switch to just grabbing the
per-crtc (and maybe per-plane) locks as needed, maybe based on
ww_mutexes. Having a callback which absolutely needs all modeset
locks is bad for this conversion.
Note that the same isn't true for the provided ->update_plane since
we've audited the crtc helpers to make sure that not encoder or
connector links are changed.
- There's no way to re-enable the plane with an ->update_plane: The
connectors/encoder links are lost and so we can't re-enable the
CRTC. Even without that issue the driver might have reassigned some
shared resources (as opposed to e.g. DPMS off, where drivers are not
allowed to do that to make sure the CRTC can be enabled again).
- The semantics don't make much sense: Userspace asked to scan out
black (or some other color if the driver supports a background
color), not that the screen be disabled.
- Implementing proper primary plane support (i.e. actually disabling
the primary plane without disabling the CRTC) is really simple, at
least if all the hw needs is flipping a bit. The big task is
auditing all the interactions with other ioctls when the CRTC is on
but there's no primary plane (e.g. pageflips). And some of that work
still needs to be done.

Commit 457e77b26428ab4a24998eecfb99f27fa4195397 added two checks applied to a
value received from nv_rd32(bios, 0x619f04). But after this new piece of code
is executed, the addr local variable does not hold the same value it used to
hold before the commit. Here is what is was assigned in the original code:
(u64)(nv_rd32(bios, 0x619f04) & 0xffffff00) << 8
in the committed code it ends up with this value:
(u64)(nv_rd32(bios, 0x619f04) >> 8) << 8
These expressions are obviously not equivalent.
My Nvidia video card does not show anything on the display when I boot a
kernel containing this commit.
The patch fixes the code so that the new checks are still done, but the
side effect of an incorrect addr value is gone.

drm/tegra: Fixes for v3.15-rc2
This contains a fix for the host1x driver writing to non-existent syncpt
registers.
A second commit removes an excess pad field in the parameter structure
for the DRM_TEGRA_SUBMIT IOCTL. Archeaology on earlier versions of this
file indicates that this was once there to pad an uneven number of u32
u32 fields, of which one was subsequently removed. Unfortunately nobody
remembered to get rid of the padding when that happened.
Both of these commits are Cc: stable because they fix issues that were
introduced back in v3.10.

BIT_WORD() truncates rather than rounds, so the loops in
syncpt_thresh_isr() and _host1x_intr_disable_all_syncpt_intrs() use <=
rather than < in an attempt to process the correct number of registers
when rounding of the conversion of count of bits to count of words is
necessary. However, when rounding isn't necessary because the value is
already a multiple of the divisor (as is the case for all values of
nb_pts the code actually sees), this causes one too many registers to
be processed.
Solve this by using and explicit DIV_ROUND_UP() call, rather than
BIT_WORD(), and comparing with < rather than <=.

With the recent primary-plane changes for drm, the primary plane's
framebuffer needs to be ref counted the same way as for
non-primary-planes. This was not done by the omapdrm driver, which
caused the ref count to drop to 0 too early, causing problems.
This patch moves the fb unref and ref from omap_plane_update to
omap_plane_mode_set. This way the fb refs are updated for both primary
and non-primary cases, as omap_plane_update calls omap_plane_mode_set.

omap_crtc->old_fb is used to check whether the previous page flip has completed
or not. However, it's never initialized to anything, so it's always NULL. This
results in the check to always succeed, and the page_flip to proceed.
Initialize old_fb to the fb that we intend to flip to through page_flip, and
therefore prevent a future page flip to proceed if the last one didn't
complete.

A waiter of the type OMAP_GEM_READ should wait for a buffer to be completely
written, and only then proceed with reading it. A similar logic applies for
waiters with OMAP_GEM_WRITE flag.
Currently the function is_waiting() waits on the read_complete/read_target
counts in the sync object.
This should be the other way round, as a reader should wait for users who are
'writing' to this buffer, and vice versa.
Make readers of the buffer(OMAP_GEM_READ) wait on the write counters, and
writers to the buffer(OMAP_GEM_WRITE) wait on the read counters in is_waiting()

At the moment the omap_crtc_pre_apply() handles the enabling, disabling
and configuring of encoders and panels separately from the CRTC (i.e.
the overlay manager).
However, this doesn't work correctly. The encoder driver has to be in
control of its video input (i.e. the crtc) for correct operation.
This problem causes bugs with (at least) HDMI: the HDMI encoder supplies
pixel clock for DISPC, and DISPC supplies video stream for HDMI. The
current code first enables the HDMI encoder, and CRTC after that.
However, the encoder expects the video stream to start during the
encoder's enable, and if it doesn't, there will be sync lost errors.
The encoder enables its video source by calling src->enable(), and this
call goes to omapdrm (omap_crtc_enable), but omapdrm doesn't do anything
in that function. Similarly for disable, which goes to
omap_crtc_disable().
This patch moves the code to setup and enable/disable the crtc to
omap_crtc_enable. and omap_crtc_disable().

At module unload, omap_fbdev_free() gets called which releases the
framebuffers. However, the framebuffers are still used by crtcs, and
will be released only later at vsync. The driver doesn't wait for this,
and goes on to release the rest of the resources, which often
causes a crash.
This patchs adds a omap_crtc_flush() function which waits until the crtc
has finished with its apply queue and page flips.
The function utilizes a simple polling while-loop, as the performance is
not an issue here.

At the moment it's quite easy to get the following errors when the HDMI
output is enabled or disabled:
[drm:omap_crtc_error_irq] *ERROR* tv: errors: 00008000
The reason for the errors is that the omapdrm driver doesn't properly
handle the sync-lost irqs that happen when enabling the DIGIT crtc,
which is used for HDMI and analog TV. The driver does disable the
sync-lost irq properly, but it fails to wait until the output has been
fully enabled (i.e. the first vsync), so the sync-lost errors are still
seen occasionally.
This patch makes the omapdrm act the same way as the omapfb does:
- When enabling a display, we'll wait for the first vsync.
- When disabling a display, we'll wait for framedone if available, or
odd and even vsyncs.
These changes make sure the output is fully enabled or disabled at the
end of the function.

This patch fixes I/O errors with the sym53c8xx_2 driver when the disk
returns QUEUE FULL status.
When the controller encounters an error (including QUEUE FULL or BUSY
status), it aborts all not yet submitted requests in the function
sym_dequeue_from_squeue.
This function aborts them with DID_SOFT_ERROR.
If the disk has full tag queue, the request that caused the overflow is
aborted with QUEUE FULL status (and the scsi midlayer properly retries
it until it is accepted by the disk), but the sym53c8xx_2 driver aborts
the following requests with DID_SOFT_ERROR --- for them, the midlayer
does just a few retries and then signals the error up to sd.
The result is that disk returning QUEUE FULL causes request failures.
The error was reproduced on 53c895 with COMPAQ BD03685A24 disk
(rebranded ST336607LC) with command queue 48 or 64 tags. The disk has
64 tags, but under some access patterns it return QUEUE FULL when there
are less than 64 pending tags. The SCSI specification allows returning
QUEUE FULL anytime and it is up to the host to retry.

Pull PCIe non-transparent bridge fixes and features from Jon Mason:
"NTB driver bug fixes to address issues in list traversal, skb leak in
ntb_netdev, a typo, and a leak of msix entries in the error path.
Clean ups of the event handling logic, as well as a overall style
cleanup. Finally, the driver was converted to use the new
pci_enable_msix_range logic (and the refactoring to go along with it)"
* tag 'ntb-3.15' of git://github.com/jonmason/ntb:
ntb: Use pci_enable_msix_range() instead of pci_enable_msix()

Pull vfs updates from Al Viro:
"The first vfs pile, with deep apologies for being very late in this
window.
Assorted cleanups and fixes, plus a large preparatory part of iov_iter
work. There's a lot more of that, but it'll probably go into the next
merge window - it *does* shape up nicely, removes a lot of
boilerplate, gets rid of locking inconsistencie between aio_write and
splice_write and I hope to get Kent's direct-io rewrite merged into
the same queue, but some of the stuff after this point is having
(mostly trivial) conflicts with the things already merged into
mainline and with some I want more testing.
This one passes LTP and xfstests without regressions, in addition to
usual beating. BTW, readahead02 in ltp syscalls testsuite has started
giving failures since "mm/readahead.c: fix readahead failure for
memoryless NUMA nodes and limit readahead pages" - might be a false
positive, might be a real regression..."

This patch fixes the initialization of an array used in the TX
datapath that was mistakenly initialized together with the
RX datapath arrays. An out of range array access could happen
when RX and TX rings had different sizes.

Jeff Kirsher says:
====================
Intel Wired LAN Driver Updates
This series contains updates to e1000, e1000e, igb, igbvf, ixgb, ixgbe,
ixgbevf and i40evf.
Mark fixes an issue with ixgbe and ixgbevf by adding a bit to indicate
when workqueues have been initialized. This permits the register read
error handling from attempting to use them prior to that, which also
generates warnings. Checking for a detected removal after initializing
the work queues allows the probe function to return an error without
getting the workqueue involved. Further, if the error_detected
callback is entered before the workqueues are initialized, exit without
recovery since the device initialization was so truncated.
Francois Romieu provides several patches to all the drivers to remove
the open coded skb_cow_head.
Jakub Kicinski provides a fix for igb where last_rx_timestamp should be
updated only when Rx time stamp is read.
Mitch provides a fix for i40evf where a recent change broke the RSS LUT
programming causing it to be programmed with all 0's.

When the device is unplugged, the driver would try to disable the
device. Add checking the flag of RTL8152_UNPLUG to skip setting
the device when it is unplugged. This could shorten the time of
unloading the driver.
