Some of the HW registers are privileged and cannot be written to from
non-privileged batch buffers coming from userspace unless they are added to
the HW whitelist. This whitelist is maintained by HW and it is different from
SW whitelist. Userspace need write access to them to implement preemption
related WA.
The reason for using this approach is, the register bits that control
preemption granularity at the HW level are not context save/restored; so even
if we set these bits always in kernel they are going to change once the
context is switched out. We can consider making them non-privileged by
default but these registers also contain other chicken bits which should not
be allowed to be modified.
In the later revisions controlling bits are save/restored at context level but
in the existing revisions these are exported via other debug registers and
should be on the whitelist. This patch adds changes to provide HW with a list
of registers to be whitelisted. HW checks this list during execution and
provides access accordingly.
HW imposes a limit on the number of registers on whitelist and it is
per-engine. At this point we are only enabling whitelist for RCS and we don't
foresee any requirement for other engines.
The registers to be whitelisted are added using generic workaround list
mechanism, even these are only enablers for userspace workarounds. But by
sharing this mechanism we get some test assets without additional cost (Mika).
v2: rebase
v3: parameterize RING_FORCE_TO_NONPRIV() as _MMIO() should be limited to
i915_reg.h (Ville), drop inline for wa_ring_whitelist_reg (Mika).
v4: improvements suggested by Chris Wilson.
Clarify that this is HW whitelist and different from the one maintained in
driver. This list is engine specific but it gets initialized along with other
WA which is RCS specific thing, so make it clear that we are not doing any
cross engine setup during initialization.
Make HW whitelist count of each engine available in debugfs.

Commit 5bab6f60cb4d ("drm/i915: Serialise updates to GGTT with access
through GGTT on Braswell") depended upon a working stop_machine() and
so forced the selection of STOP_MACHINE. However, commit 86fffe4a61dd
("kernel: remove stop_machine() Kconfig dependency") removed the option
STOP_MACHINE from init/Kconfig and ensured that stop_machine()
universally works. Due to the order in which the patches were applied,
removing the select from DRM_I915 got lost during merging.
Remove the now obsolete select statement.

There is no guarantee that on fsl_ssi module load
SSI registers will have their power-on-reset values.
In fact, if the driver is reloaded the values in
registers will be whatever they were set to previously.
However, the cache needs to be fully populated at probe
time to avoid non-atomic allocations during register
access.
Special case here is imx21-class SSI, since
according to datasheet it don't have SACC{ST,EN,DIS}
regs.
This fixes hard lockup on fsl_ssi module reload,
at least in AC'97 mode.

With CONFIG_V4L2=m and VIDEO_SAMSUNG_EXYNOS4_IS=y, we can select the
individual drivers as built-in code when that should not be possible:
drivers/built-in.o: In function `s5pcsis_set_fmt':
policy.c:(.text+0x13afdc): undefined reference to `v4l_bound_align_image'
drivers/built-in.o: In function `s5pcsis_probe':

policy.c:(.text+0x13b72c): undefined reference to `v4l2_subdev_init'
Changing VIDEO_SAMSUNG_EXYNOS4_IS to tristate means that the dependency
from CONFIG_V4L2 propates to the individual Kconfig symbols and they
can only be built as loadable modules if V4L2 or any other of the
dependencies itself is a module.

The FIFO is used for ir_raw_event records, however for some historic
reason the FIFO is used on a per byte basis. IMHO this adds unneeded
complexity. Therefore set up the FIFO for ir_raw_event records.
This also allows to define the FIFO statically as part of
ir_raw_event_ctrl instead of having to allocate the FIFO dynamically.
In addition:
- When writing into the FIFO and it's full return ENOSPC instead of
ENOMEM thus making it easier to tell between "FIFO full" and
"Dynamic memory allocation failed" when the error is propagated to
a higher level.
Also add an error message.
- When reading from the FIFO check whether it's empty.
This is not strictly needed here but kfifo_out is annotated
"must check" anyway.
Successfully tested it with the nuvoton-cir driver.

And right he is! The Authenticode specification is a paragon amongst
technical documents, and has this pearl of wisdom to offer:
---------------------------------
Authenticode-Specific SignerInfo UnauthenticatedAttributes Structures
The following Authenticode-specific data structures are present in
SignerInfo authenticated attributes.
SpcSpOpusInfo
SpcSpOpusInfo is identified by SPC_SP_OPUS_INFO_OBJID
(1.3.6.1.4.1.311.2.1.12) and is defined as follows:
SpcSpOpusInfo ::= SEQUENCE {
programName [0] EXPLICIT SpcString OPTIONAL,
moreInfo [1] EXPLICIT SpcLink OPTIONAL,
} --#public--
SpcSpOpusInfo has two fields:
programName
This field contains the program description:
If publisher chooses not to specify a description, the SpcString
structure contains a zero-length program name.
If the publisher chooses to specify a
description, the SpcString structure contains a Unicode string.
moreInfo
This field is set to an SPCLink structure that contains a URL for
a Web site with more information about the signer. The URL is an
ASCII string.
---------------------------------
Which is to say that this is an optional *unauthenticated* field which
may be present in the Authenticated Attribute list. This is not how
pkcs7 is supposed to work, so when David implemented this, he didn't
appreciate the subtlety the original spec author was working with, and
missed the part of the sublime prose that says this Authenticated
Attribute is an Unauthenticated Attribute. As a result, the code in
question simply takes as given that the Authenticated Attributes should
be authenticated.
But this one should not, individually. Because it says it's not
authenticated.
It still has to hash right so the TBS digest is correct. So it is both
authenticated and unauthenticated, all at once. Truly, a wonder of
technical accomplishment.
Additionally, pesign's implementation has always attempted to be
compatible with the signatures emitted from contemporary versions of
Microsoft's signtool.exe. During the initial implementation, Microsoft
signatures always produced the same values for SpcSpOpusInfo -
{U"Microsoft Windows", "http://www.microsoft.com"} - without regard to
who the signer was.
Sometime between Windows 8 and Windows 8.1 they stopped including the
field in their signatures altogether, and as such pesign stopped
producing them in commits c0c4da6 and d79cb0c, sometime around June of
2012. The theory here is that anything that breaks with
pesign signatures would also be breaking with signtool.exe sigs as well,
and that'll be a more noticed problem for firmwares parsing it, so it'll
get fixed. The fact that we've done exactly this bug in Linux code is
first class, grade A irony.
So anyway, we should not be checking this field for presence or any
particular value: if the field exists, it should be at the right place,
but aside from that, as long as the hash matches the field is good.

Recently, it has been reported that D-Link DWA-582 cards, which use an
RTL8812AE chip are not able to scan for 5G networks. The problems started
with kernel 4.2, which is the first version that had commit d10101a60372
("rtlwifi: rtl8821ae: Fix problem with regulatory information"). With this
patch, the driver went from setting a default channel plan to using
the value derived from EEPROM.
Bug reports at https://bugzilla.kernel.org/show_bug.cgi?id=111031 and
https://bugzilla.redhat.com/show_bug.cgi?id=1279653 are examples of this
problem.
The problem was solved once I learned that the internal country code was
resulting in a regulatory set with only 2.4 GHz channels. With the RTL8821AE
chips available to me, the country code was such that both 2.4 and 5 GHz
channels are allowed. The fix is to allow both bands even when the EEPROM
is incorrectly encoded.

After power-up, the tvp5150 decoder is in a unknown state until the
RESETB pin is driven LOW which reset all the registers and restarts
the chip's internal state machine.
The init sequence has some timing constraints and the RESETB signal
can only be used if the PDN (Power-down) pin is first released.
So, the initialization sequence is as follows:
1- PDN (active-low) is driven HIGH so the chip is power-up
2- A 20 ms delay is needed before sending a RESETB (active-low) signal.
3- The RESETB pulse duration is 500 ns.
4- A 200 us delay is needed for the I2C client to be active after reset.
This patch used as a reference the logic in the IGEPv2 board file from
the ISEE 2.6.37 vendor tree.

Most PLL's don't actually have LOCK_ENABLE bits. However, most PLL's
also had that flag set, which meant that the clk code was trying to
enable locks, and inadvertantly flipping bits in other fields.
For PLLM, ensure the correct register is used for the misc_register.
PLL_MISC0 contains the EN_LCKDET bit which should be used for enabling
the lock, and PLLM_MISC1 shouldn't be used at all.
Lastly, remove some of the settings which would point to the EN_LCKDET
bits for some PLLs. There is no need to enable the locks, and that is
done as part of the set_defaults logic already.

In certain kernel configurations where the cdc_ether and option drivers
are compiled as modules there can occur a race condition in enumeration.
This causes the option driver to enumerate the ethernet(wwan) interface
as usb-serial interfaces.

The build of m32r allmodconfig fails with the error:
drivers/media/v4l2-core/videobuf2-dma-contig.c:484:2:
error: implicit declaration of function 'dma_get_cache_alignment'
The build of videobuf2-dma-contig.c depends on HAS_DMA and it is
correctly mentioned in the Kconfig but the symbol VIDEO_STI_BDISP also
selects VIDEOBUF2_DMA_CONTIG, so it is trying to compile
videobuf2-dma-contig.c even though HAS_DMA is not defined.

Some user space use cases result in kernel hangup on the HIC_OPEN_SENSOR
command write. In case when a minimalistic application is used for setting
up the streaming, the hangups occur only occasionally. In case of GStreamer
use cases it is always the case.

In order to allow for automatic media device entities linking
from the level of libv4l plugin the open system call shouldn't
fail, as the libv4l plugins can begin their job not until it
succeeds.
This patch allows for leaving the pipeline not linked on
open and postpones verifying it to the moment when streamon
callback is called.

VIDIOC_SUBDEV_G_FMT ioctl should return TRY format previously
set with VIDIOC_SUBDEV_S_FMT. Currently it is not the case as
only ACTIVE formats are saved in the driver. Since the driver
doesn't alter hardware state in the set_fmt op anyway, the
op can save the format in both TRY and ACTIVE case.

As of commit e488ca9f8d4f62c2 ("doc: dt: mtd: partitions: add compatible
property to "partitions" node"), the "partitions" subnode of an SPI
FLASH device node must have a compatible property. The partitions are no
longer detected if it is not present.
