Commit 8211dad627 ("s390: add pte_free_defer() for pgtables sharing
page") added a warning to pte_free_defer(), on our request. It was meant
to warn if this would ever be reached for KVM guest mappings, because
the page table would be freed w/o a gmap_unlink(). THP mappings are not
allowed for KVM guests on s390, so this should never happen.
However, it is possible that the warning is triggered in a valid case as
false-positive.
s390_enable_sie() takes the mmap_lock, marks all VMAs as VM_NOHUGEPAGE and
splits possibly existing THP guest mappings. mm->context.has_pgste is set
to 1 before that, to prevent races with the mm_has_pgste() check in
MADV_HUGEPAGE.
khugepaged drops the mmap_lock for file mappings and might run in parallel,
before a vma is marked VM_NOHUGEPAGE, but after mm->context.has_pgste was
set to 1. If it finds file mappings to collapse, it will eventually call
pte_free_defer(). This will trigger the warning, but it is a valid case
because gmap is not yet set up, and the THP mappings will be split again.
Therefore, remove the warning and the comment.

Add 50ms disable delay for NV116WHM-N49, NV122WUM-N41, and MNC207QS1-1
to satisfy T9+T10 timing. Add 50ms disable delay for MNE007JA1-2
as well, since MNE007JA1-2 copies the timing of MNC207QS1-1.
Specifically, it should be noted that the MNE007JA1-2 panel was added
by someone who did not have the panel documentation, so they simply
copied the timing from the MNC207QS1-1 panel. Adding an extra 50 ms
of delay should be safe.

In January 2015, tracefs was created to allow access to the tracing
infrastructure without needing to compile in debugfs. When tracefs is
configured, the directory /sys/kernel/tracing will exist and tooling is
expected to use that path to access the tracing infrastructure.
To allow backward compatibility, when debugfs is mounted, it would
automount tracefs in its "tracing" directory so that tooling that had hard
coded /sys/kernel/debug/tracing would still work.
It has been over 10 years since the new interface was introduced, and all
tooling should now be using it. Start the process of deprecating the old
path so that it doesn't need to be maintained anymore.
A new config is added to allow distributions to disable automounting of
tracefs on debugfs.
If /sys/kernel/debug/tracing is accessed, a pr_warn() will trigger stating:
"NOTICE: Automounting of tracing to debugfs is deprecated and will be removed in 2030"
Expect to remove this feature in 5 years (2030).

The Event_Type field in an LE Extended Advertising Report uses bits 5
and 6 for data status (e.g. truncation or fragmentation), not the PDU
type itself.
The ext_evt_type_to_legacy() function fails to mask these status bits
before evaluation. This causes valid advertisements with status bits set
(e.g. a truncated non-connectable advertisement, which ends up showing
as PDU type 0x40) to be misclassified as unknown and subsequently
dropped. This is okay for most checks which use bitwise AND on the
relevant event type bits, but it doesn't work for non-connectable types,
which are checked with '== LE_EXT_ADV_NON_CONN_IND' (that is, zero).
In terms of behaviour, first the device sends a truncated report:
> HCI Event: LE Meta Event (0x3e) plen 26
LE Extended Advertising Report (0x0d)
Entry 0
Event type: 0x0040
Data status: Incomplete, data truncated, no more to come
Address type: Random (0x01)
Address: 1D:12:46:FA:F8:6E (Non-Resolvable)
SID: 0x03
RSSI: -98 dBm (0x9e)
Data length: 0x00
Then, a few seconds later, it sends the subsequent complete report:
> HCI Event: LE Meta Event (0x3e) plen 122
LE Extended Advertising Report (0x0d)
Entry 0
Event type: 0x0000
Data status: Complete
Address type: Random (0x01)

SID: 0x03
RSSI: -97 dBm (0x9f)
Data length: 0x60

These devices often send multiple truncated reports per second.
This patch introduces a PDU type mask to ensure only the relevant bits
are evaluated, allowing for the correct translation of all valid
extended advertising packets.

The firmware raises an alive interrupt upon sending the HCI_RESET or
BTINTEL_HCI_OP_RESET command. As part of handling the reset command,
firmware initializes the hardware and data path and raises the alive
interrupt. Upon receiving the alive interrupt, the driver must enable
the data path and grant RX buffers to the firmware before sending any
commands.
The alive context maintained in the driver must be updated before
sending BTINTEL_HCI_OP_RESET or HCI_OP_RESET to prevent a potential race
condition where the context is also updated in the threaded IRQ.
The issue was observed in a stress reboot usecase (1/25) using "sudo
reboot" command where the firmware download was failing as the driver
was not granting RX buffer to firmware due to race condition.

The firmware raises an alive interrupt upon receiving the HCI_RESET or
BTINTEL_HCI_OP_RESET (Intel reset - 0xfc01) command. This change fixes
the driver to properly wait for the alive interrupt to avoid driver
sending commands to firmware before it is ready to process.
For details on the handshake between the driver and firmware, refer to
commit 05c200c8f0 ("Bluetooth: btintel_pcie: Add handshake between

As the driver needs to handle two interrupts for HCI_OP_RESET and
BTINTEL_HCI_OP_RESET, the firmware ensures that the TX completion
interrupt is always followed by the alive interrupt.

Currently both dev_coredumpv and skb_put_data in hci_devcd_dump use
hdev->dump.head. However, dev_coredumpv can free the buffer. From
dev_coredumpm_timeout documentation, which is used by dev_coredumpv:
> Creates a new device coredump for the given device. If a previous one hasn't
> been read yet, the new coredump is discarded. The data lifetime is determined
> by the device coredump framework and when it is no longer needed the @free
> function will be called to free the data.
If the data has not been read by the userspace yet, dev_coredumpv will
discard new buffer, freeing hdev->dump.head. This leads to
vmalloc-out-of-bounds error when skb_put_data tries to access
hdev->dump.head.

This adds uevents which will be generated whenever FW dump is triggered,
FW dump is complete and FW (re)download is done.
This feature is needed for IW612 chipset, which is a tri-radio chipset,
where WLAN runs on CPU1 and BT and Zigbee runs on CPU2.
Currently, whenever BT FW crashes, and FW dump is in progress, there is

it will be recovered.
With the help of these uevents and udev rules, the 15.4 app, or any
userspace application can be alerted whenever CPU2 goes in bad state and
recoveres after BTNXPUART reloads the firmware.

This adds proper handling for the independent reset command sent by the
driver after FW dump is complete.
In normal scenario, the independent reset vendor command gives a success
response before jumping to bootcode.
However, when FW goes in a bad state, and sends out FW dump packets, the
independent reset command does not get any response from the controller.

As a fix for such scenario, the independent reset vendor command is sent
using the __hci_cmd_send() API, which does not expect any response for
vendor commands.
__hci_cmd_send is non blocking, so before the tx_work is scheduled, it
sometimes gets canceled and 3F|FC command is never sent. Adding a small
delay after __hci_cmd_send allows the command to be sent to the
controller.

User applications need a way to track which ISO interval a given SDU

timestamps, and it's not guaranteed user application receives all packet
reports (small socket buffer, or controller doesn't send all reports
like Intel AX210 is doing).
Add socket option BT_PKT_SEQNUM that enables reporting of received
packet ISO sequence number in BT_SCM_PKT_SEQNUM CMSG.

This adds support for 4000000 as secondary baudrate.
This value is selected from device tree property "max-speed"
which is then used to download FW chunks, and as operational baudrate after
HCI initialization is done.
Earlier, the secondary baudrate was fixed to 3000000 in driver, but now
with "max-speed" property, this secondary baudrate can be set to
4000000.
The secondary baudrate is set by the driver by sending a vendor command
(3F 09) to the firmware, with secondary baudrate parameter, in
nxp_post_init().
Any other value set for max-speed other than 3000000 or 4000000 will
default to 3000000, which is supported by all legacy and new NXP chipsets.
This feature is applicable for all new V3 bootloader chips and w8987 V1
bootloader chip.
This property does not apply for w8997 compatible device, since it
downloads a helper.bin FW file that sets secondary baudrate as 3000000
only.
The switch to 4000000 baudrate is validated using a Saleae Logic Analyzer
and imx8m-mini with AW693 M.2 module.

Add support for 4000000 as secondary baudrate for NXP chipsets
supporting max baudrate as 4M, and are close to the host processor on
same PCB. This mainly helps with faster FW download.

HCI_EV_EXTENDED_INQUIRY_RESULT's comment wrongly uses 0x2d as its event
code.
Use right 0x2f instead.

Eliminate an unnecessary goto label by using break instead of goto to
exit the loop in hci_find_irk_by_addr().
