If the whole object is already pinned by HW for use as scanout, we will

This fixes regression introduced by
commit 8d52af6795c0 ("mei: speed up the power down flow")
In power down or suspend flow a message can still be received
from the FW because the clients fake disconnection.
In normal case we interpret messages w/o destination as corrupted
and link reset is performed in order to clean the channel,
but during power down link reset is already in progress resulting
in endless loop. To resolve the issue under power down flow we
discard messages silently.

The touch sensors on the 2nd-gen Intuos tablets don't use a 4096x4096
sensor like other similar tablets (3rd-gen Bamboo, Intuos5, etc.).
The incorrect maximum XY values don't normally affect userspace since
touch input from these devices is typically relative rather than
absolute. It does, however, cause problems when absolute distances
need to be measured, e.g. for gesture recognition. Since the resolution
of the touch sensor on these devices is 10 units / mm (versus 100 for
the pen sensor), the proper maximum values can be calculated by simply
dividing by 10.

Card write threshold control is supposed to be set since controller
version 2.80a for data write in HS400 mode and data read in
HS200/HS400/SDR104 mode. However the current code returns without
configuring it in the case of data writing in HS400 mode.
Meanwhile the patch fixes that the current code goes to
'disable' when doing data reading in HS400 mode.

Sometimes when writing large size files to flash in direct/memory mapped
mode, it is seen that flash write enable command times out with error:
[ 503.146293] cadence-qspi 47040000.ospi: Flash command execution timed out.
This is because, we need to make sure previous direct write operation
is complete by polling for IDLE bit in CONFIG_REG before starting the
next operation.
Fix this by polling for IDLE bit after memory mapped write.

Currently, we use the ACPI processor ID only for the leaf/processor nodes
as the specification states it must match the value of the ACPI processor
ID field in the processor’s entry in the MADT.
However, if a PPTT structure represents a processors group, it
matches a processor container UID in the namespace and the
ACPI_PPTT_ACPI_PROCESSOR_ID_VALID flag indicates whether the
ACPI processor ID is valid.
Let's use UID whenever ACPI_PPTT_ACPI_PROCESSOR_ID_VALID is set to be
consistent instead of using table offset as it's currently done for
non-leaf nodes.

Remove dependencies on HAS_DMA where a Kconfig symbol depends on another
symbol that implies HAS_DMA, and, optionally, on "|| COMPILE_TEST".
In most cases this other symbol is an architecture or platform specific
symbol, or PCI.
Generic symbols and drivers without platform dependencies keep their
dependencies on HAS_DMA, to prevent compiling subsystems or drivers that
cannot work anyway.
This simplifies the dependencies, and allows to improve compile-testing.

Commit f2a8aa053c17 ("typec: tcpm: Represent source supply through
power_supply") moved the code to register a power_supply representing
the device supplying power to the type-C connector, from the fusb302
code to the generic tcpm code.
This has caused the power-supply registered by the fusb302 driver,
which determines how much current the bq24190 can draw, to change name
from "fusb302-typec-source" to "tcpm-source-psy-i2c-fusb302".

Commit f2a8aa053c17 ("typec: tcpm: Represent source supply through
power_supply") moved the code to register a power_supply representing
the device supplying power to the type-C connector, from the fusb302
code to the generic tcpm code so that we have a psy reporting the
supply voltage and current for all tcpm devices.
This broke the reporting of current and voltage through the psy interface
when supplied by a a non pd supply (5V, current as reported by
get_current_limit). The cause of this breakage is port->supply_voltage
and port->current_limit not being set in that case.
This commit fixes this by setting port->supply_voltage and
port->current_limit from tcpm_set_current_limit().
This commit also removes setting supply_voltage and current_limit
from tcpm_reset_port() as that calls tcpm_set_current_limit(0, 0)
which now already sets these to 0.

There have been several reports of LPM related hard freezes about once
a day on multiple Lenovo 50 series models. Strange enough these reports
where not disk model specific as LPM issues usually are and some users
with the exact same disk + laptop where seeing them while other users
where not seeing these issues.
It turns out that enabling LPM triggers a firmware bug somewhere, which
has been fixed in later BIOS versions.
This commit adds a new ahci_broken_lpm() function and a new ATA_FLAG_NO_LPM
for dealing with this.
The ahci_broken_lpm() function contains DMI match info for the 4 models
which are known to be affected by this and the DMI BIOS date field for
known good BIOS versions. If the BIOS date is older then the one in the
table LPM will be disabled and a warning will be printed.
Note the BIOS dates are for known good versions, some older versions may
work too, but we don't know for sure, the table is using dates from BIOS
versions for which users have confirmed that upgrading to that version
makes the problem go away.
Unfortunately I've been unable to get hold of the reporter who reported
that BIOS version 2.35 fixed the problems on the W541 for him. I've been
able to verify the DMI_SYS_VENDOR and DMI_PRODUCT_VERSION from an older
dmidecode, but I don't know the exact BIOS date as reported in the DMI.
Lenovo keeps a changelog with dates in their release notes, but the
dates there are the release dates not the build dates which are in DMI.
So I've chosen to set the date to which we compare to one day past the
release date of the 2.34 BIOS. I plan to fix this with a follow up
commit once I've the necessary info.

The driver gets TX completions via the TX status ring. Each
status message points to the completed descriptor ring and
includes the number of completed descriptors in this ring.
Non TSO enhanced DMA TX descriptors are similar to legacy DMA

However, enhanced DMA TSO frames division is performed by the

Enhanced DMA design includes the following rings:
- Single RX descriptor ring is used for all VIFs
- Multiple RX status rings are supported, to allow RSS
- TX descriptor ring is allocated per connection
- A single TX status ring is used for all TX descriptor rings
This patch initializes and frees the above descriptor and
status rings.
The RX SKBs are handled by a new entity of RX buffers manager,
which handles RX buffers, each one points to an allocated SKB.
During Rx completion processing, the driver extracts a buffer
ID which is used as an index to the buffers array.
After the SKB is freed the buffer is moved from the 'active'
list to the 'free' list, indicating it can be used for another
descriptor. During Rx refill, SKBs are allocated and attached
to 'free' buffers. Those buffers are attached to new descriptors
and moved to the 'active' list.
New debugfs entries were added to allow edma configuration:
Run the following command to configure the number of status rings:
echo NUM_OF_STATUS_RINGS > num_rx_status_rings
Run the following command to use extended RX status message for
additional debug fields from HW:
echo 0 > compressed_rx_status
Run the following command to control the size of the TX status ring:
echo TX_STATUS_RING_ORDER > tx_status_ring_order
The status ring size will be 1 << tx_status_ring_order
Run the following command to control the size of the RX status ring:
echo RX_STATUS_RING_ORDER > rx_status_ring_order
Due to HW constrains RX sring order should be bigger than RX ring order
The status ring size will be 1 << rx_status_ring_order
Run the following command to change the number of RX buffer IDs:
echo RX_BUFF_ID_COUNT > rx_buff_id_count

In enhanced DMA the vrings are handled internally by the FW
and are not exposed to the driver.
Instead, the driver handles descriptor rings, which are mapped
by the FW to vrings.
The completions of the TX and RX descriptors are notified to
the driver using status rings. Each status ring descriptor
includes information of the completed descriptors and the ring id
of their descriptor ring.
This patch changes struct vring to generic wil_ring to allow
its reuse for enhanced DMA descriptor rings and adds the descriptor
and status rings specific descriptors.
The vring debugfs entries have changed as follows:
- dbg_vring_index has changed to dbg_ring_index
- vrings has changed to rings
- vring_idle_trsh has changed to ring_idle_trsh
- vring_index has changed to ring_index

We have
struct drbd_requests { ... struct bio *private_bio; ... }
to hold a bio clone for local submission.
On local IO completion, we put that bio, and in case we want to use the
result later, we overload that member to hold the ERR_PTR() of the
completion result,
Which, before v4.3, used to be the passed in "int error",
so we could first bio_put(), then assign.
v4.3-rc1~100^2~21 4246a0b63bd8 block: add a bi_error field to struct bio
changed that:
bio_put(req->private_bio);
- req->private_bio = ERR_PTR(error);
+ req->private_bio = ERR_PTR(bio->bi_error);
Which introduces an access after free,
because it was non obvious that req->private_bio == bio.
Impact of that was mostly unnoticable, because we only use that value
in a multiple-failure case, and even then map any "unexpected" error
code to EIO, so worst case we could potentially mask a more specific
error with EIO in a multiple failure case.
Unless the pointed to memory region was unmapped, as is the case with
CONFIG_DEBUG_PAGEALLOC, in which case this results in
BUG: unable to handle kernel paging request
v4.13-rc1~70^2~75 4e4cbee93d56 block: switch bios to blk_status_t
changes it further to
bio_put(req->private_bio);
req->private_bio = ERR_PTR(blk_status_to_errno(bio->bi_status));
And blk_status_to_errno() now contains a WARN_ON_ONCE() for unexpected
values, which catches this "sometimes", if the memory has been reused
quickly enough for other things.
Should also go into stable since 4.3, with the trivial change around 4.13.

Without this, when receiving a packet that has this flag set
from firmware, we will read invalid trailer data from the packet,
which will be shown as various errors, e.g. "sdio mbox lookahead
is zero" or "invalid rx packet" or "payload length x exceeds max
htc length".

All packets in a bundle should use the same endpoint id as the
first lookahead.
This matches how things are done is ath6kl, however,
this patch can theoretically handle several bundles
in ath10k_sdio_mbox_rx_process_packets().
Without this patch we get lots of errors about invalid endpoint id:
ath10k_sdio mmc2:0001:1: invalid endpoint in look-ahead: 224
ath10k_sdio mmc2:0001:1: failed to get pending recv messages: -12
ath10k_sdio mmc2:0001:1: failed to process pending SDIO interrupts: -12

This patch is fixes an issue that the SDHI_INTERNAL_DMAC_RX_IN_USE
flag cannot be cleared because tmio_mmc_core sets the host->data
to NULL before the tmio_mmc_core calls tmio_mmc_abort_dma().
So, this patch clears the SDHI_INTERNAL_DMAC_RX_IN_USE in
the renesas_sdhi_internal_dmac_abort_dma() anyway. This doesn't
cause any side effects.
