At this point, there is nothing left to fail. And submit already has a
fence assigned and is added to the submit_list. Any problems from here
on out are asynchronous (ie. hangcheck/recovery).

The MDP4 driver tries to request and set voltages for regulators required
by the DSI PLLs.
Firstly, the MDP4 driver shouldn't manage the DSI regulators, this should
be handled in the DSI driver. Secondly, it shouldn't try to set a fixed
voltage for regulators. Voltage constraints should be specified on the
regulator via DT and managed by the regulator core.
Remove all the DSI PLL regulator related code from the MDP4 driver. It's
managed in the DSI driver for MSM8960/APQ8064 already.

The eDP driver tries to set a fixed voltage for one of its regulators(vdda)
before enabling it. This shouldn't be done by the driver, the voltage
constraints should be specified on the regulator via DT and managed by
the regulator core. A driver should call regulator_set_voltage only if
it needs to change the voltage during runtime. Drop the
regulator_set_voltage call. Mention in a comment the voltage that the
regulator expects.

The voltage changing code in this driver is broken and should be
removed. The driver sets a single, exact voltage on probe. Unless
there is a very good reason for this (which should be documented in
comments) constraints like this need to be set via the machine
constraints, voltage setting in a driver is expected to be used in cases
where the voltage varies at runtime.
In addition client drivers should almost never be calling
regulator_can_set_voltage(), if the device needs to set a voltage it
needs to set the voltage and the regulator core will handle the case
where the regulator is fixed voltage. If the driver simply skips
setting the voltage if it doesn't have permission then it should just
not bother in the first place.
Originally authored by Mark Brown <broonie@kernel.org>
Remove the min/max voltage data entries per SoC managed by the driver.
These aren't needed as we don't try to set voltages any more. Mention in
comments the voltages that each regulator expects.

Here, a location is reset to NULL before being passed to PTR_ERR.
So, PTR_ERR should be called before its argument is reassigned
to NULL. Further to simplify things use PTR_ERR_OR_ZERO instead
of PTR_ERR and IS_ERR.

A recent cleanup removed the only user of the 'kms' variable in
msm_preclose(), causing a harmless compiler warning:
drivers/gpu/drm/msm/msm_drv.c: In function 'msm_preclose':

It is no longer true that we discard all in-flight submits on recover
(these days we only discard the first one that hung). After the first
re-submitted batch completes it would overwrite the fence with a correct
value, but there would be a window of time which showed all re-submitted
batches as already complete.

This was only used for atomic commit these days. So instead just give

Better encapsulate the per-timeline stuff into fence-context. For now
there is just a single fence-context, but eventually we'll also have one

Split up locking and pinning buffers in the submit path. This is needed
because we'll want to insert fencing in between the two steps.
This makes things end up looking more similar to etnaviv submit code
(which was originally modelled on the msm code but has already added
'struct fence' support).

Since we already track the array of bo's in the submit object, just
unconditionally take and drop ref's per submit (rather than only taking
ref's if bo is not already active). This simplifies later patches.

In the atomic modesetting path, each driver simply wants to grab a ref
to the exclusive fence from a reservation object to store in the incoming
drm_plane_state, without doing the whole RCU dance. Since each driver
will need to do this, lets make a helper.

If the DMAs are not being quiesced properly, it may lead to

M-Audio Profire 610 has an unexpected value in version field of its config
ROM, thus ALSA dice driver is not assigned to the model due to a mismatch
of modalias.
This commit adds an entry to support the model. I expect the entry is
also for Profire 2626.
I note that Profire 610 uses TCD2220 (so-called Dice Jr.), and supports a
part of Extended Application Protocol (EAP).

Payloads of NM entries are not supposed to contain NUL. When we run
into such, only the part prior to the first NUL goes into the
concatenation (i.e. the directory entry name being encoded by a bunch
of NM entries). We do stop when the amount collected so far + the
claimed amount in the current NM entry exceed 254. So far, so good,
but what we return as the total length is the sum of *claimed*
sizes, not the actual amount collected. And that can grow pretty
large - not unlimited, since you'd need to put CE entries in
between to be able to get more than the maximum that could be
contained in one isofs directory entry / continuation chunk and
we are stop once we'd encountered 32 CEs, but you can get about 8Kb
easily. And that's what will be passed to readdir callback as the
name length. 8Kb __copy_to_user() from a buffer allocated by
__get_free_page()

When cxgb4 is enabled with CONFIG_CHELSIO_T4_DCB set, VI enable command
gets called with DCB enabled. But when we have a back to back setup with
DCB enabled on one side and non-DCB on the Peer side. Firmware doesn't
send any DCB_L2_CFG, and DCB priority is never set for Tx queue.
But driver resets the queue priority and state machine whenever there
is a link down, this patch fixes it by adding a check to reset only if
cxgb4_dcb_enabled() returns true.

The reason is: in recovery flow, we use delayed iput mechanism for directory
which has recovered dentry block. It means the reference of inode will be
held until last dirty dentry page being writebacked.
But when we mount f2fs with inline_dentry option, during recovery, dirent
may only be recovered into dir inode page rather than dentry page, so there
are no chance for us to release inode reference in ->writepage when
writebacking last dentry page.
We can call paired iget/iput explicityly for inline_dentry case, but for
non-inline_dentry case, iput will call writeback_single_inode to write all
data pages synchronously, but during recovery, ->writepages of f2fs skips
writing all pages, result in losing dirent.
This patch fixes this issue by obsoleting old mechanism, and introduce a
new dir_list to hold all directory inodes which has recovered datas until
finishing recovery.

This patch allows fscrypto to handle a second key prefix given by filesystem.
The main reason is to provide backward compatibility, since previously f2fs
used "f2fs:" as a crypto prefix instead of "fscrypt:".
Later, ext4 should also provide key_prefix() to give "ext4:".
One concern decribed by Ted would be kinda double check overhead of prefixes.
In x86, for example, validate_user_key consumes 8 ms after boot-up, which turns
out derive_key_aes() consumed most of the time to load specific crypto module.
After such the cold miss, it shows almost zero latencies, which treats as a
negligible overhead.
Note that request_key() detects wrong prefix in prior to derive_key_aes() even.

The following panic occurs when truncating inode which has inline
xattr to max filesize.

The reason is truncate_blocks tries to truncate all node and data blocks
start from specified block offset with value of (max filesize / block
size), but actually, our valid max block offset is (max filesize / block
size) - 1, so f2fs detects such invalid block offset with BUG_ON in
truncation path.
This patch lets f2fs skip truncating data which is exceeding max
filesize.

Currently, generic_block_bmap is used in f2fs_bmap, its semantics is when
the mapping is been found, return position of target physical block,
otherwise return zero.
But, previously, when there is no mapping info for specified logical block,
f2fs_bmap will map target physical block to a uninitialized variable, which
should be wrong. Fix it.

Even if an inode failed to release its blocks, it should be kept in an orphan
inode list, so it will be released later.
