f628d79997 libceph: add sparse read support to OSD client 
Have get_reply check for the presence of sparse read ops in the
request and set the sparse_read boolean in the msg. That will queue the
messenger layer to use the sparse read codepath instead of the normal
data receive.

Add a new sparse_read operation for the OSD client, driven by its own
state machine. The messenger will repeatedly call the sparse_read
operation, and it will pass back the necessary info to set up to read
the next extent of data, while zero-filling the sparse regions.

The state machine will stop at the end of the last extent, and will
attach the extent map buffer to the ceph_osd_req_op so that the caller
can use it.

d396f89db3 libceph: add sparse read support to msgr1 
Add 2 new fields to ceph_connection_v1_info to track the necessary info
in sparse reads. Skip initializing the cursor for a sparse read.

Break out read_partial_message_section into a wrapper around a new
read_partial_message_chunk function that doesn't zero out the crc first.

Add new helper functions to drive receiving into the destinations
provided by the sparse_read state machine.

f36217e35c libceph: support sparse reads on msgr2 secure codepath 
Add a new init_sgs_pages helper that populates the scatterlist from
an arbitrary point in an array of pages.

Change setup_message_sgs to take an optional pointer to an array of
pages. If that's set, then the scatterlist will be set using that
array instead of the cursor.

When given a sparse read on a secure connection, decrypt the data
in-place rather than into the final destination, by passing it the
in_enc_pages array.

After decrypting, run the sparse_read state machine in a loop, copying
data from the decrypted pages until it's complete.

ec3bc567ea libceph: new sparse_read op, support sparse reads on msgr2 crc codepath 
Add support for a new sparse_read ceph_connection operation. The idea is
that the client driver can define this operation use it to do special
handling for incoming reads.

The alloc_msg routine will look at the request and determine whether the
reply is expected to be sparse. If it is, then we'll dispatch to a
different set of state machine states that will repeatedly call the
driver's sparse_read op to get length and placement info for reading the
extent map, and the extents themselves.

This necessitates adding some new field to some other structs:

- The msg gets a new bool to track whether it's a sparse_read request.

- A new field is added to the cursor to track the amount remaining in the
current extent. This is used to cap the read from the socket into the
msg_data

- Handing a revoke with all of this is particularly difficult, so I've
added a new data_len_remain field to the v2 connection info, and then
use that to skip that much on a revoke. We may want to expand the use of
that to the normal read path as well, just for consistency's sake.

a679e50f72 libceph: define struct ceph_sparse_extent and add some helpers 
When the OSD sends back a sparse read reply, it contains an array of
these structures. Define the structure and add a couple of helpers for
dealing with them.

Also add a place in struct ceph_osd_req_op to store the extent buffer,
and code to free it if it's populated when the req is torn down.

08b8a0440e libceph: add spinlock around osd->o_requests 
In a later patch, we're going to need to search for a request in
the rbtree, but taking the o_mutex is inconvenient as we already
hold the con mutex at the point where we need it.

Add a new spinlock that we take when inserting and erasing entries from
the o_requests tree. Search of the rbtree can be done with either the
mutex or the spinlock, but insertion and removal requires both.

[   96.389025] Chain exists of:

[   96.413429]  Possible unsafe locking scenario:

[   96.413446]

An ioctl call IOCTL_XENBUS_BACKEND_SETUP (record #1 in the report)
results in calling xenbus_alloc() -> xs_suspend() which introduces
ordering xs_watch_rwsem --> xs_response_mutex. The xenbus_thread()
operation (record #2) creates xs_response_mutex --> &u->msgbuffer_mutex.
An XS_WATCH write to the xenbus file then results in a complain about
the opposite lock order &u->msgbuffer_mutex --> xs_watch_rwsem.

The dependency xs_watch_rwsem --> xs_response_mutex is spurious. Avoid
it and the warning by changing the ordering in xs_suspend(), first
acquire xs_response_mutex and then xs_watch_rwsem. Reverse also the
unlocking order in xs_suspend_cancel() for consistency, but keep
xs_resume() as is because it needs to have xs_watch_rwsem unlocked only
after exiting xs suspend and re-adding all watches.

When switching from 10GBase-R/5GBase-R/USXGMII to one of the interface
modes provided by mtk-pcs-lynxi we need to make sure to always perform
a full configuration of the PHYA.

Implement pcs_disable op which resets the stored interface mode to
PHY_INTERFACE_MODE_NA to trigger a full reconfiguration once the LynxI
PCS driver had previously been deselected in favor of another PCS
driver such as the to-be-added driver for the USXGMII PCS found in
MT7988.

be80942465 selftests: bonding: do not set port down before adding to bond 
Before adding a port to bond, it need to be set down first. In the
lacpdu test the author set the port down specifically. But commit
a4abfa627c ("net: rtnetlink: Enslave device before bringing it up")
changed the operation order, the kernel will set the port down _after_
adding to bond. So all the ports will be down at last and the test failed.

In fact, the veth interfaces are already inactive when added. This
means there's no need to set them down again before adding to the bond.
Let's just remove the link down operation.

e332938e6f samples: ftrace: Replace bti assembly with hint for older compiler 
When cross-building the arm64 kernel with allmodconfig using GCC 9.4,
the following error occurs on multiple files under samples/ftrace/:

/tmp/ccPC1ODs.s: Assembler messages:
/tmp/ccPC1ODs.s:8: Error: selected processor does not support `bti c'

Fix this issue by replacing `bti c` with `hint 34`, which is compatible
for the older compiler.

 SoC, the BeagleV Ahead. As with the Lichee Pi 4a, this is sufficient
 only for booting to a console, with work on the mmc, clocks and ethernet
 sides of things under way. A relicense to a dual licence for the
 existing devicetree files is also done, for good measure.

b89c940f2a New boards are the NanoPC T6, Firefly Station P2, Radxa Rock 4SE. 
Many new peripherals for the still only basic supported rk3588 soc
 (PCIe2, PCIe3, USB2, SATA, Combo-Phys).
 
 Improvements to the Rock-5a development board based on this soc (saradc,
 i2c on dsi and csi, fan, eeprom, analog audio, leds, sd-card,
 some regulators, pmic).
 
 Improvements for the edgeble-neu6b (rs485, rs232, pwm-fan, rtc, sata,
 sata, sd-card, pmic)
 
 RK3399 got the PCIe endpoint node when used as a PCIe-client.
 
 And some minor changes for some boards: spi-flash for RockPi 4,
 SATA and fixed PCIe regulators for Radxa E25 and using enable-gpios
 on engicam and gru boards.

Merge tag 'v6.6-rockchip-dts64-1' of git://git.kernel.org/pub/scm/linux/kernel/git/mmind/linux-rockchip into soc/dt

New boards are the NanoPC T6, Firefly Station P2, Radxa Rock 4SE.

Many new peripherals for the still only basic supported rk3588 soc
(PCIe2, PCIe3, USB2, SATA, Combo-Phys).

Improvements to the Rock-5a development board based on this soc (saradc,
i2c on dsi and csi, fan, eeprom, analog audio, leds, sd-card,
some regulators, pmic).

Improvements for the edgeble-neu6b (rs485, rs232, pwm-fan, rtc, sata,
sata, sd-card, pmic)

RK3399 got the PCIe endpoint node when used as a PCIe-client.

And some minor changes for some boards: spi-flash for RockPi 4,
SATA and fixed PCIe regulators for Radxa E25 and using enable-gpios
on engicam and gru boards.

With this change the structure size is reduced by 8 bytes, below is the

};

The validation code in the netvsc driver is affected by changing the
struct size, but the effects have been examined and have been determined
to be appropriate.

78e04bbff8 Drivers: hv: vmbus: Don't dereference ACPI root object handle 
Since the commit referenced in the Fixes: tag below the VMBus client driver
is walking the ACPI namespace up from the VMBus ACPI device to the ACPI
namespace root object trying to find Hyper-V MMIO ranges.

However, if it is not able to find them it ends trying to walk resources of
the ACPI namespace root object itself.
This object has all-ones handle, which causes a NULL pointer dereference
in the ACPI code (from dereferencing this pointer with an offset).

This in turn causes an oops on boot with VMBus host implementations that do
not provide Hyper-V MMIO ranges in their VMBus ACPI device or its
ancestors.
The QEMU VMBus implementation is an example of such implementation.

I guess providing these ranges is optional, since all tested Windows
versions seem to be able to use VMBus devices without them.

Fix this by explicitly terminating the lookup at the ACPI namespace root
object.

Note that Linux guests under KVM/QEMU do not use the Hyper-V PV interface
by default - they only do so if the KVM PV interface is missing or
disabled.

9eb33ddedd Qualcomm driver updates for v6.6 
Compatible and clock handling in the Qualcomm SCM driver is cleaned up,
 together with a couple stylistic cleanups and transition to mark
 exported symbols GPL only.
 
 An abstraction for the RPM subsystem is introduced, to make align the
 structure of the SMD and GLINK nodes thereof with the structure when a
 remoteproc is involved. This is done to facilitate associating
 additional entities with the RPM subsystem.
 
 The qmp_send() API is modified to not expose hardware requirements onto
 the client drivers, and then further extended to allow command
 formatting directly in the API, to facilitate this typical use case.
 
 In the Qualcomm Command DB driver, NUL characters previously included in
 identifiers are dropped from the debugfs, to facilitate scripting.
 
 The thresholds of the BWMON driver are simplified to avoid hard coded
 starting values.
 
 The OCMEM driver is updated with some cleanups and fixes, and addition
 of MSM8226 support.
 
 PMIC_GLINK gains support for retimer switches, safe mode is selected
 when the cable is disconnected from altmode and the same is enabled for
 SM8550.
 
 An off-by-one string length check is corrected in the QMI encoder
 decoder library.
 
 The RPMh tracepoints are extended to include the state of the request,
 to provide needed context in the traced events.
 
 The series from Ulf creating a genpd framework is integrated, to
 facilitate the other changes to the cpr, rpmpd and rpmhpd driver.
 SDX75 support is added to the rpmhpd driver, and the rpmpd driver is
 extended with the same sync_state logic found in the rpmhpd driver.
 
 The socinfo driver gains knowledge about SM4450 and SM7125, the IPQ5019
 platform is dropped.
 
 Clock handling in the GSBI driver is cleaned up with the use of
 devm_clk_get_enabled().
 
 The list of VMIDs defined for the SCM assign memory interface is
 extended.

====================
bpf: Add multi uprobe link

hi,
this patchset is adding support to attach multiple uprobes and usdt probes
through new uprobe_multi link.

The current uprobe is attached through the perf event and attaching many
uprobes takes a lot of time because of that.

The main reason is that we need to install perf event for each probed function
and profile shows perf event installation (perf_install_in_context) as culprit.

The new uprobe_multi link just creates raw uprobes and attaches the bpf
program to them without perf event being involved.

In addition to being faster we also save file descriptors. For the current
uprobe attach we use extra perf event fd for each probed function. The new
link just need one fd that covers all the functions we are attaching to.

v7 changes:
  - fixed task release on error path and re-org the error
    path to be more straightforward [Yonghong]
  - re-organized uprobe_prog_run locking to follow general pattern
    and removed might_fault check as it's not needed in uprobe/task
    context [Yonghong]

There's support for bpftrace [2] and tetragon [1].
