radeon_copy_dma and radeon_copy_blit must be called with
a valid reservation object. Otherwise a crash will be provoked.
We borrow the object from destination BO.

If acceleration is disabled, it does not make sense
to init gpuvm since nothing will use it. Moreover,
if radeon_vm_init() gets called it uses accel to try
and clear the pde tables, etc. which results in a bug.

This is a workaround for RS880 and older chips which seem to have
an additional limit on the minimum PLL input frequency.

It seems in the past we have BDW with PCH not been propperly identified
and we force it to be LPT and we were warning !IS_HASWELL on propper identification.
Now that products are out there we are receiveing logs with this incorrect WARN.
And also according to local tests on all production BDW here ULT or HALO we don't
need this force anymore. So let's clean this block for real.
v2: Fix LPT_LP WARNs to avoid wrong warns on BDW_ULT (By Jani).

When creating a fence for a tiled object, only fence the area that
makes up the actual tiles. The object may be larger than the tiled
area and if we allow those extra addresses to be fenced, they'll
get converted to addresses beyond where the object is mapped. This
opens up the possiblity of writes beyond the end of object.
To prevent this, we adjust the size of the fence to only encompass
the area that makes up the actual tiles. The extra space is considered
un-tiled and now behaves as if it was a linear object.

commit 6dda730e55f412a6dfb181cae6784822ba463847
Author: Jani Nikula <jani.nikula@intel.com>
Date: Tue Jun 24 18:27:40 2014 +0300
drm/i915: respect the VBT minimum backlight brightness
introduced a bug which resulted in inconsistent brightness levels on
different machines. If a suspended was entered with the screen off some
machines would resume with the screen at minimum brightness and others
at maximum brightness.
The following commands can be used to produce this behavior.
xset dpms force off
sleep 1
sudo systemctl suspend
(resume ...)
The root cause of this problem is a comparison which checks to see if
the backlight level is zero when the panel is enabled. If it is zero,
it is set to the maximum level. Unfortunately, not all machines have a
minimum level of zero. On those machines the level is left at the
minimum instead of begin set to the maximum.
Fix the bug by updating the comparison to check for the minimum
backlight level instead of zero. Also, expand the comparison for
the possible case when the level is less than the minimum.

Commit 82460d972 ("drm/i915: Rework ppgtt init to no require an aliasing
ppgtt") introduced a regression on Broadwell, triggering the following
IOMMU fault at startup:
vgaarb: device changed decodes: PCI:0000:00:02.0,olddecodes=io+mem,decodes=io+mem:owns=io+mem
dmar: DRHD: handling fault status reg 2
dmar: DMAR:[DMA Write] Request device [00:02.0] fault addr 880000
DMAR:[fault reason 23] Unknown
fbcon: inteldrmfb (fb0) is primary device
Further commentary from Daniel:
I sugggested this change to David after staring at the offending patch
for a while. I have no idea and theory whatsoever why this would upset
the gpu less than the other way round. But it seems to work. David
promised to chase hw people a bit more to get a more meaningful answer.
Wrt the comment that this deletes: I've done some digging and afaict
loading context before ppgtt enable was once required before our recent
restructuring of the context/ppgtt init code: Before that context sw
setup (i.e. allocating the default context) and hw setup was smashed
together. Also the setup of the default context was the bit that
actually allocated the aliasing ppgtt structures. Which is the reason
for the context before ppgtt depency.
Or was, since with all the untangling there's no no real depency any
more (functional, who knows what the hw is doing), so the comment is
just stale.

VT switch back/forth from console to xserver (for example) has potential
to go horribly wrong if a dynamic DP MST connector ends up in the saved
modeset that is restored when switching back to fbcon.
When removing a dynamic connector, don't forget to clean up the saved
state.
v1: original
v2: null out set->fb if no more connectors to avoid making i915 cranky

You can't modify the metadata in these modes. It's better to fail these

metadata blocks. Otherwise these failed metadata changes will trigger
'needs_check' to get set in the metadata superblock -- requiring repair
using the thin_check utility.

This function call was being optimized out during nfs_fhget(), leading
to situations where we have a valid fileid but still want to use the
mounted_on_fileid. For example, imagine we have our server configured
like this:
server % df
Filesystem Size Used Avail Use% Mounted on
/dev/vda1 9.1G 6.5G 1.9G 78% /
/dev/vdb1 487M 2.3M 456M 1% /exports
/dev/vdc1 487M 2.3M 456M 1% /exports/vol1
/dev/vdd1 487M 2.3M 456M 1% /exports/vol2
If our client mounts /exports and tries to do a "chown -R" across the
entire mountpoint, we will get a nasty message warning us about a circular
directory structure. Running chown with strace tells me that each directory
has the same device and inode number:
newfstatat(AT_FDCWD, "/nfs/", {st_dev=makedev(0, 38), st_ino=2, ...}) = 0
newfstatat(4, "vol1", {st_dev=makedev(0, 38), st_ino=2, ...}) = 0
newfstatat(4, "vol2", {st_dev=makedev(0, 38), st_ino=2, ...}) = 0
With this patch the mounted_on_fileid values are used for st_ino, so the
directory loop warning isn't reported.

We only support swap file calling nfs_direct_IO. However, application
might be able to get to nfs_direct_IO if it toggles O_DIRECT flag
during IO and it can deadlock because we grab inode->i_mutex in
nfs_file_direct_write(). So return 0 for such case. Then the generic
layer will fall back to buffer IO.

This effectively reverts the last hunk of 392a9dad7e77 ("rbd: detect
when clone image is flattened").
The problem with parent_overlap != 0 condition is that it's possible
and completely valid to have an image with parent_overlap == 0 whose
parent state needs to be cleaned up on unmap. The next commit, which
drops the "clone image now standalone" logic, opens up another window
of opportunity to hit this, but even without it
# cat parent-ref.sh
#!/bin/bash
rbd create --image-format 2 --size 1 foo
rbd snap create foo@snap
rbd snap protect foo@snap
rbd clone foo@snap bar
rbd resize --allow-shrink --size 0 bar
rbd resize --size 1 bar
DEV=$(rbd map bar)
rbd unmap $DEV
leaves rbd_device/rbd_spec/etc and rbd_client along with ceph_client
hanging around.
My thinking behind calling rbd_dev_parent_put() unconditionally is that
there shouldn't be any requests in flight at that point in time as we
are deep into unmap sequence. Hence, even if rbd_dev_unparent() caused
by flatten is delayed by in-flight requests, it will have finished by
the time we reach rbd_dev_unprobe() caused by unmap, thus turning
unconditional rbd_dev_parent_put() into a no-op.

The comment for rbd_dev_parent_get() said
* We must get the reference before checking for the overlap to
* coordinate properly with zeroing the parent overlap in
* rbd_dev_v2_parent_info() when an image gets flattened. We
* drop it again if there is no overlap.
but the "drop it again if there is no overlap" part was missing from
the implementation. This lead to absurd parent_ref values for images
with parent_overlap == 0, as parent_ref was incremented for each
img_request and virtually never decremented.
Fix this by leveraging the fact that refresh path calls
rbd_dev_v2_parent_info() under header_rwsem and use it for read in
rbd_dev_parent_get(), instead of messing around with atomics. Get rid
of barriers in rbd_dev_v2_parent_info() while at it - I don't see what
they'd pair with now and I suspect we are in a pretty miserable
situation as far as proper locking goes regardless.

When the last subscriber to a "Through" port has been removed, the
subscribed destination ports might still be active, so it would be
wrong to send "all sounds off" and "reset controller" events to them.
The proper place for such a shutdown would be the closing of the actual
MIDI port (and close_substream() in rawmidi.c already can do this).
This also fixes a deadlock when dummy_unuse() tries to send events to
its own port that is already locked because it is being freed.

ASoC: Fixes for v3.19
There's a lot more fixes here than I'd like since I've been lax in
sending things throughout the release cycle but there's only two in
generic code and they've had quite some time to cook in -next so
hopefully on balance are OK.
The two generic fixes are a fix for crashes on capture DAIs in the
compress code and a fix for error handling on probe failures which would
have been harmless in the past but now oopses with the new dynamic probe
code.

If asoc_simple_card_probe() fails, asoc_simple_card_unref() may be
called before dev_set_drvdata(), causing a NULL pointer dereference in
asoc_simple_card_unref():
Unable to handle kernel NULL pointer dereference at virtual address 000000d4
...
PC is at asoc_simple_card_unref+0x14/0x48
LR is at asoc_simple_card_probe+0x3d4/0x40c
This typically happens because asoc_simple_card_parse_of() returns
-EPROBE_DEFER, but other failure modes are possible.
devm_snd_soc_register_card()/snd_soc_register_card() may fail either
before or after dev_set_drvdata().
Pass a snd_soc_card pointer instead of a platform_device pointer to
asoc_simple_card_unref() to fix this.
Note that if CONFIG_OF_DYNAMIC=n, of_node_put() is a dummy, and gcc may
optimize away the loop over card->dai_link, never actually dereferencing
card, and thus avoiding the crash...

The offset of block allocator, ba->offset, should not be changed during
fixed address allocating, for the caller may treat it as the offset of
allocated memory and use it. In the case that we allocate more than 1
blocks, we should make sure this offset is correct.
Here introduces a temp allocator for the later continuous allocating.

The following crash happens when trying to unload the snd_soc_imx_wm8962 module
while playback is active:

...
In order to avoid such problem, fill the card owner field as suggested by
Lars-Peter Clausen:
"But looking at the source it seems that this is a core feature of ALSA and at
least for the card module itself it will do the ref-counting when a stream is
started/stopped. And we even support setting the owner of a card in ASoC.
It's just that pretty much no ASoC card driver bothers to set the owner field
in the snd_soc_card struct. So this particular problem can be fixed by updating
the imx-wm8962 driver to set the owner field."
By doing as suggested, we no longer see the crash when attempting to unload the
snd_soc_imx_wm8962 module while playback is active:

In soc_new_compress() when rtd->dai_link->dynamic is set, we create the pcm
substreams with this call:
ret = snd_pcm_new_internal(rtd->card->snd_card, new_name, num,
1, 0, &be_pcm);
which passes 0 as capture_count leading to
be_pcm->streams[SNDRV_PCM_STREAM_CAPTURE].substream
being NULL, hence when trying to set rtd a few lines below we get an oops.
Fix by using rtd->dai_link->dpcm_playback and rtd->dai_link->dpcm_capture as
playback_count and capture_count to snd_pcm_new_internal().

Today we expect that all the bank are enabled, and count the number of banks
used by the pinctrl based on it instead of using the last bank id enabled.
So switch to it, set the chained IRQ at runtime based on enabled banks
and wait only the number of enabled gpio controllers at probe time.

The stack guard page error case has long incorrectly caused a SIGBUS
rather than a SIGSEGV, but nobody actually noticed until commit
fee7e49d4514 ("mm: propagate error from stack expansion even for guard
page") because that error case was never actually triggered in any
normal situations.
Now that we actually report the error, people noticed the wrong signal
that resulted. So far, only the test suite of libsigsegv seems to have
actually cared, but there are real applications that use libsigsegv, so
let's not wait for any of those to break.

The core VM already knows about VM_FAULT_SIGBUS, but cannot return a
"you should SIGSEGV" error, because the SIGSEGV case was generally
handled by the caller - usually the architecture fault handler.
That results in lots of duplication - all the architecture fault
handlers end up doing very similar "look up vma, check permissions, do
retries etc" - but it generally works. However, there are cases where
the VM actually wants to SIGSEGV, and applications _expect_ SIGSEGV.
In particular, when accessing the stack guard page, libsigsegv expects a
SIGSEGV. And it usually got one, because the stack growth is handled by
that duplicated architecture fault handler.
However, when the generic VM layer started propagating the error return
from the stack expansion in commit fee7e49d4514 ("mm: propagate error
from stack expansion even for guard page"), that now exposed the
existing VM_FAULT_SIGBUS result to user space. And user space really
expected SIGSEGV, not SIGBUS.
To fix that case, we need to add a VM_FAULT_SIGSEGV, and teach all those
duplicate architecture fault handlers about it. They all already have
the code to handle SIGSEGV, so it's about just tying that new return
value to the existing code, but it's all a bit annoying.
This is the mindless minimal patch to do this. A more extensive patch
would be to try to gather up the mostly shared fault handling logic into
one generic helper routine, and long-term we really should do that
cleanup.
Just from this patch, you can generally see that most architectures just
copied (directly or indirectly) the old x86 way of doing things, but in
the meantime that original x86 model has been improved to hold the VM
semaphore for shorter times etc and to handle VM_FAULT_RETRY and other
"newer" things, so it would be a good idea to bring all those
improvements to the generic case and teach other architectures about
them too.

"This feels larger than I'd like but its for three reasons.
a) amdkfd finalising the API more, this is a new feature introduced
last merge window, and I'd prefer to make the tweaks to the API
before it first gets into a stable release.
b) radeon regression required splitting an internal API to fix
properly, so it just changed a few more lines
c) vmwgfx fix changes a lock from a mutex->spin lock, this is fallout
from the new sleep checking.
Otherwise there is just some tda998x fixes"
