61f6f68447 remoteproc: k3-r5: Wait for core0 power-up before powering up core1
PSC controller has a limitation that it can only power-up the second core
when the first core is in ON state. Power-state for core0 should be equal
to or higher than core1, else the kernel is seen hanging during rproc
loading.

Make the powering up of cores sequential, by waiting for the current core
to power-up before proceeding to the next core, with a timeout of 2sec.
Add a wait queue event in k3_r5_cluster_rproc_init call, that will wait
for the current core to be released from reset before proceeding with the
next core.

2ca178f02b libbpf: Add support for kprobe session attach
Adding support to attach program in kprobe session mode
with bpf_program__attach_kprobe_multi_opts function.

Adding session bool to bpf_kprobe_multi_opts struct that allows
to load and attach the bpf program via kprobe session.

Also adding new program loader section that allows:
 SEC("kprobe.session/bpf_fentry_test*")

and loads/attaches kprobe program as kprobe session.

5c919acef8 bpf: Add support for kprobe session cookie
Adding support for cookie within the session of kprobe multi
entry and return program.

The session cookie is u64 value and can be retrieved be new
kfunc bpf_session_cookie, which returns pointer to the cookie
value. The bpf program can use the pointer to store (on entry)
and load (on return) the value.

The cookie value is implemented via fprobe feature that allows
to share values between entry and return ftrace fprobe callbacks.

adf46d88ae bpf: Add support for kprobe session context
Adding struct bpf_session_run_ctx object to hold session related
data, which is atm is_return bool and data pointer coming in
following changes.

Placing bpf_session_run_ctx layer in between bpf_run_ctx and
bpf_kprobe_multi_run_ctx so the session data can be retrieved
regardless of if it's kprobe_multi or uprobe_multi link, which
support is coming in future. This way both kprobe_multi and
uprobe_multi can use same kfuncs to access the session data.

Adding bpf_session_is_return kfunc that returns true if the
bpf program is executed from the exit probe of the kprobe multi
link attached in wrapper mode. It returns false otherwise.

Adding new kprobe hook for kprobe program type.

535a3692ba bpf: Add support for kprobe session attach
Adding support to attach bpf program for entry and return probe
of the same function. This is common use case which at the moment
requires to create two kprobe multi links.

Adding new BPF_TRACE_KPROBE_SESSION attach type that instructs
kernel to attach single link program to both entry and exit probe.

It's possible to control execution of the bpf program on return
probe simply by returning zero or non zero from the entry bpf
program execution to execute or not the bpf program on return
probe respectively.

6f572a8054 drm/nouveau/gsp: Use the sg allocator for level 2 of radix3
Currently we allocate all 3 levels of radix3 page tables using
nvkm_gsp_mem_ctor(), which uses dma_alloc_coherent() for allocating all of
the relevant memory. This can end up failing in scenarios where the system
has very high memory fragmentation, and we can't find enough contiguous
memory to allocate level 2 of the page table.

Currently, this can result in runtime PM issues on systems where memory
fragmentation is high - as we'll fail to allocate the page table for our
suspend/resume buffer:

Luckily, we don't actually need to allocate coherent memory for the page
table thanks to being able to pass the GPU a radix3 page table for
suspend/resume data. So, let's rewrite nvkm_gsp_radix3_sg() to use the sg
allocator for level 2. We continue using coherent allocations for lvl0 and
1, since they only take a single page.

V2:
* Don't forget to actually jump to the next scatterlist when we reach the
  end of the scatterlist we're currently on when writing out the page table
  for level 2

got the very same PCI SSID while the hardware implementations are
completely different (the former is with TI TAS2781 codec while the
latter is with Cirrus CS35L41 codec).  The former model got broken by
the recent fix for the latter model.

For addressing the regression, check the codec SSID and apply the
proper quirk for each model now.

7033ada04e i40e: Refactor argument of i40e_detect_recover_hung()
Commit 07d44190a3 ("i40e/i40evf: Detect and recover hung queue
scenario") changes i40e_detect_recover_hung() argument type from
i40e_pf* to i40e_vsi* to be shareable by both i40e and i40evf.
Because the i40evf does not exist anymore and the function is
exclusively used by i40e we can revert this change.

54c4664e48 i40e: Refactor argument of several client notification functions
Commit 0ef2d5afb1 ("i40e: KISS the client interface") simplified
the client interface so in practice it supports only one client
per i40e netdev. But we have still 2 notification functions that
uses as parameter a pointer to VSI of netdevice associated with
the client. After the mentioned commit only possible and used
VSI is the main (LAN) VSI.
So refactor these functions so they are called with PF pointer argument
and the associated VSI (LAN) is taken inside them.

c78c3644b7 usb: Fix regression caused by invalid ep0 maxpacket in virtual SuperSpeed device
A virtual SuperSpeed device in the FreeBSD BVCP package
(https://bhyve.npulse.net/) presents an invalid ep0 maxpacket size of 256.
It stopped working with Linux following a recent commit because now we
check these sizes more carefully than before.

Fix this regression by using the bMaxpacketSize0 value in the device
descriptor for SuperSpeed or faster devices, even if it is invalid.  This
is a very simple-minded change; we might want to check more carefully for
values that actually make some sense (for instance, no smaller than 64).

fe81f35484 usb: ohci: Prevent missed ohci interrupts
Testing ohci functionality with qemu's pci-ohci emulation often results
in ohci interface stalls, resulting in hung task timeouts.

The problem is caused by lost interrupts between the emulation and the
Linux kernel code. Additional interrupts raised while the ohci interrupt
handler in Linux is running and before the handler clears the interrupt
status are not handled. The fix for a similar problem in ehci suggests
that the problem is likely caused by edge-triggered MSI interrupts. See
commit 0b60557230 ("usb: ehci: Prevent missed ehci interrupts with
edge-triggered MSI") for details.

Ensure that the ohci interrupt code handles all pending interrupts before
returning to solve the problem.

Jakub Kicinski says:

====================
selftests: net: page_poll allocation error injection

Add a test for exercising driver memory allocation failure paths.
page pool is a bit tricky to inject errors into at the page allocator
level because of the bulk alloc and recycling, so add explicit error
injection support "in front" of the caches.

Add a test to exercise that using only the standard APIs.
This is the first useful test for the new tests with an endpoint.
There's no point testing netdevsim here, so this is also the first
HW-only test in Python.

I'm not super happy with the traffic generation using iperf3,
my initial approach was to use mausezahn. But it turned out to be
5x slower in terms of PPS. Hopefully this is good enough for now.

9da271f825 selftests: drv-net-hw: add test for memory allocation failures with page pool
Bugs in memory allocation failure paths are quite common.
Add a test exercising those paths based on qstat and page pool
failure hook.

Running on bnxt:

  # ./drivers/net/hw/pp_alloc_fail.py
  KTAP version 1
  1..1
  # ethtool -G change retval: success
  ok 1 pp_alloc_fail.test_pp_alloc
  # Totals: pass:1 fail:0 xfail:0 xpass:0 skip:0 error:0

I initially wrote this test to validate commit be43b7489a ("net/mlx5e:
RX, Fix page_pool allocation failure recovery for striding rq") but mlx5
still doesn't have qstat. So I run it on bnxt, and while bnxt survives
I found the problem fixed in commit 7301177307 ("eth: bnxt: fix counting
packets discarded due to OOM and netpoll").

The main use of the ip() wrapper over cmd() is that it can parse JSON.
cmd("ip -j link show") will return stdout as a string, and test has
to call json.loads(). With ip("link show", json=True) the return value
will be already parsed.

More tools (ethtool, bpftool etc.) support the --json switch.
To avoid having to wrap all of them individually create a tool()
helper.

Switch from -j to --json (for ethtool).
While at it consume the netns attribute at the ip() level.

spi: xlp: use 'time_left' variable with wait_for_completion_timeout()
There is a confusing pattern in the kernel to use a variable named 'timeout' to
store the result of wait_for_completion_timeout() causing patterns like:

	timeout = wait_for_completion_timeout(...)
	if (!timeout) return -ETIMEDOUT;

with all kinds of permutations. Use 'time_left' as a variable to make the code
self explaining.

Fix to the proper variable type 'unsigned long' while here.

spi: sun6i: use 'time_left' variable with wait_for_completion_timeout()
There is a confusing pattern in the kernel to use a variable named 'timeout' to
store the result of wait_for_completion_timeout() causing patterns like:

	timeout = wait_for_completion_timeout(...)
	if (!timeout) return -ETIMEDOUT;

with all kinds of permutations. Use 'time_left' as a variable to make the code
self explaining.

Fix to the proper variable type 'unsigned long' while here.
