a97d8ffac8 Merge tag 'qcom-drivers-for-5.11' of git://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into arm/drivers
Qualcomm driver updates for v5.11

This adds support for the core power domains on MSM8916, MSM8939, SDM660
and SDX55. It adds SM8150 support to the last-level cache controller
driver and it makes it possible to build the Command DB and RPMh drivers
as modules.

It also contains a slew of smaller cleanups, style and bug fixes
throughout the various drivers.

f119cc9818 net: stmmac: overwrite the dma_cap.addr64 according to HW design
The current IP register MAC_HW_Feature1[ADDR64] only defines
32/40/64 bit width, but some SOCs support others like i.MX8MP
support 34 bits but it maps to 40 bits width in MAC_HW_Feature1[ADDR64].
So overwrite dma_cap.addr64 according to HW real design.

a39d2ef78d Qualcomm ARM64 DT updates for 5.11
For SM8250 the recently introduced support for handling boot-loader
 stream mappings in the ARM SMMU allow us to enable this, and thereby USB
 controller and PHY, SDHCI controller and FastRPC, as well as support for
 the SM8250 HDK board has been added. Additionally PRNG and RTC is
 enabled.
 
 Similarly for SM8150, the ARM SMMU could be added which allows the
 secondary USB controller and PHYs, as well as WiFi to be added and
 support for the SM8150 HDK board to be introduced. Additionally
 Coresight and support for the last-level cache controller was added.
 
 MSM8916 finally has VDDCX and VDDMX removed as regulators and are now
 handled by the rpmpd driver for the devices controlling them. The
 Longsheer L8150 gains touchscreen, sensors, vibrator and LED support.
 
 MSM8992 gains USB and SDHCI support as well as an I2C controller and the
 associated RMI4 based touchscreen for the Lumia 950.
 
 MSM8994 also gains USB and SDHCI support, as well as VADC and temp-alarm
 support. Then support for the Lumia 950 XL is added.
 
 SDM845 gains interconnect properties for a number of devices and the
 GENI wrappers gains iommu stream configuration, which means DMA
 operations on e.g. I2C now works. The Lenovo Yoga C630 finally has the
 SMMU enabled, a few fixes and the description of the eDP bridge and
 panel means that the laptop can now boot mainline with working display,
 GPU, WiFi and audio.
 
 SC7180 gains a slew of smaller improvements and fixes.

007ab53455 bonding: fix feature flag setting at init time
Don't try to adjust XFRM support flags if the bond device isn't yet
registered. Bad things can currently happen when netdev_change_features()
is called without having wanted_features fully filled in yet. This code
runs both on post-module-load mode changes, as well as at module init
time, and when run at module init time, it is before register_netdevice()
has been called and filled in wanted_features. The empty wanted_features
led to features also getting emptied out, which was definitely not the
intended behavior, so prevent that from happening.

Originally, I'd hoped to stop adjusting wanted_features at all in the
bonding driver, as it's documented as being something only the network
core should touch, but we actually do need to do this to properly update
both the features and wanted_features fields when changing the bond type,
or we get to a situation where ethtool sees:

    esp-hw-offload: off [requested on]

I do think we should be using netdev_update_features instead of
netdev_change_features here though, so we only send notifiers when the
features actually changed.

Fixes: a3b658cfb6 ("bonding: allow xfrm offload setup post-module-load")

fefe8527a1 iommu/io-pgtable: Remove tlb_flush_leaf
The only user of tlb_flush_leaf is a particularly hairy corner of the
Arm short-descriptor code, which wants a synchronous invalidation to
minimise the races inherent in trying to split a large page mapping.
This is already far enough into "here be dragons" territory that no
sensible caller should ever hit it, and thus it really doesn't need
optimising. Although using tlb_flush_walk there may technically be
more heavyweight than needed, it does the job and saves everyone else
having to carry around useless baggage.

7b3d5a90cb btrfs: introduce ZONED feature flag
This patch introduces the ZONED incompat flag. The flag indicates that
the volume management will satisfy the constraints imposed by
host-managed zoned block devices (aligned chunk allocation, append-only
updates, reset zone after filled).

As the zoned support will happen incrementally due to enhancing some
core infrastructure like super block writes, tree-log, raid support, the
feature will appear in sysfs only on debug builds. It will be enabled
once the support is feature complete and applications can reliably check
whether zoned support is present or not.

cc00bcaa58 netfilter: x_tables: Switch synchronization to RCU
When running concurrent iptables rules replacement with data, the per CPU
sequence count is checked after the assignment of the new information.
The sequence count is used to synchronize with the packet path without the
use of any explicit locking. If there are any packets in the packet path using
the table information, the sequence count is incremented to an odd value and
is incremented to an even after the packet process completion.

The new table value assignment is followed by a write memory barrier so every
CPU should see the latest value. If the packet path has started with the old
table information, the sequence counter will be odd and the iptables
replacement will wait till the sequence count is even prior to freeing the
old table info.

However, this assumes that the new table information assignment and the memory
barrier is actually executed prior to the counter check in the replacement
thread. If CPU decides to execute the assignment later as there is no user of
the table information prior to the sequence check, the packet path in another
CPU may use the old table information. The replacement thread would then free
the table information under it leading to a use after free in the packet
processing context-

Unable to handle kernel NULL pointer dereference at virtual
address 000000000000008e
pc : ip6t_do_table+0x5d0/0x89c

This could be fixed by forcing instruction order after the new table
information assignment or by switching to RCU for the synchronization.

fb01a2932e blk-mq: add new API of blk_mq_hctx_set_fq_lock_class
flush_end_io() may be called recursively from some driver, such as
nvme-loop, so lockdep may complain 'possible recursive locking'.
Commit b3c6a5997541("block: Fix a lockdep complaint triggered by
request queue flushing") tried to address this issue by assigning
dynamically allocated per-flush-queue lock class. This solution
adds synchronize_rcu() for each hctx's release handler, and causes
horrible SCSI MQ probe delay(more than half an hour on megaraid sas).

Add new API of blk_mq_hctx_set_fq_lock_class() for these drivers, so
we just need to use driver specific lock class for avoiding the
lockdep warning of 'possible recursive locking'.

Others need to be fixed, as kernel-doc markups should use this format:

6e0954b11c RDMA/uverbs: Allow drivers to create a new HW object during rereg_mr
mlx5 has an ugly flow where it tries to allocate a new MR and replace the
existing MR in the same memory during rereg. This is very complicated and
buggy. Instead of trying to replace in-place inside the driver, provide
support from uverbs to change the entire HW object assigned to a handle
during rereg_mr.

Since destroying a MR is allowed to fail (ie if a MW is pointing at it)
and can't be detected in advance, the algorithm creates a completely new
uobject to hold the new MR and swaps the IDR entries of the two objects.

The old MR in the temporary IDR entry is destroyed, and if it fails
rereg_mr succeeds and destruction is deferred to FD release. This
complexity is why this cannot live in a driver safely.

4d9b952857 Bluetooth: Change MGMT security info CMD to be more generic
For advertising, we wish to know the LE tx power capabilities of the
controller in userspace, so this patch edits the Security Info MGMT
command to be more generic, such that other various controller
capabilities can be included in the EIR data. This change also includes
the LE min and max tx power into this newly-named command.

The change was tested by manually verifying that the MGMT command
returns the tx power range as expected in userspace.

7c395ea521 Bluetooth: Query LE tx power on startup
Queries tx power via HCI_LE_Read_Transmit_Power command when the hci
device is initialized, and stores resulting min/max LE power in hdev
struct. If command isn't available (< BT5 support), min/max values
both default to HCI_TX_POWER_INVALID.

This patch is manually verified by ensuring BT5 devices correctly query
and receive controller tx power range.

9bf9f4b630 Bluetooth: Use intervals and tx power from mgmt cmds
This patch takes the min/max intervals and tx power optionally provided
in mgmt interface, stores them in the advertisement struct, and uses
them when configuring the hci requests. While tx power is not used if
extended advertising is unavailable, software rotation will use the min
and max advertising intervals specified by the client.

This change is validated manually by ensuring the min/max intervals are
propagated to the controller on both hatch (extended advertising) and
kukui (no extended advertising) chromebooks, and that tx power is
propagated correctly on hatch. These tests are performed with multiple
advertisements simultaneously.

1241057283 Bluetooth: Break add adv into two mgmt commands
This patch adds support for the new advertising add interface, with the
first command setting advertising parameters and the second to set
advertising data. The set parameters command allows the caller to leave
some fields "unset", with a params bitfield defining which params were
purposefully set. Unset parameters will be given defaults when calling
hci_add_adv_instance. The data passed to the param mgmt command is
allowed to be flexible, so in the future if bluetoothd passes a larger
structure with new params, the mgmt command will ignore the unknown
members at the end.

This change has been validated on both hatch (extended advertising) and
kukui (no extended advertising) chromebooks running bluetoothd that
support this new interface. I ran the following manual tests:
- Set several (3) advertisements using modified test_advertisement.py
- For each, validate correct data and parameters in btmon trace
- Verified both for software rotation and extended adv

Automatic test suite also run, testing many (25) scenarios of single and
multi-advertising for data/parameter correctness.

ASoC: SOF: trace: Add runtime trace filtering mechanism
The "filter" debugfs file defines the log levels used by
the firmware and reported by sof-logger.

The file contains the formatted entry list, where each entry
follows the following syntax in plain text:
log_level uuid_id pipe_id comp_id;

This file may be updated by userspace applications such sof-logger,
or directly by the user during debugging process.

An unused (wildcard) pipe_id or comp_id value should be set to -1,
uuid_id is hexadecimal value, so when unused then should be set to 0.

When the file is modified, an IPC command is sent to FW with new
trace levels for selected components in filter elements list.

e9a66489c3 media: doc: pixfmt-rgb: Clarify naming scheme for RGB formats
The naming scheme for the RGB pixel formats has been developed
organically, and isn't consistent between formats using less than 8 bits
per pixels (mostly stored in 1 or 2 bytes per pixel, except for RGB666
that uses 4 bytes per pixel) and formats with 8 bits per pixel (stored
in 3 or 4 bytes). For the latter category, the names use a components
order convention that is the opposite of the first category, and the
opposite of DRM pixel formats. This has led to lots of confusion in the
past, and would really benefit from being explained more precisely. Do
so, which also prepares for the addition of additional RGB pixels
formats.
