Jiri Olsa says:
====================
bpf: Introduce kprobe_multi session attach
hi,
adding support to attach kprobe program through kprobe_multi link
in a session mode, which means:
- program is attached to both function entry and return
- entry program can decided if the return program gets executed
- entry program can share u64 cookie value with return program
The initial RFC for this was posted in [0] and later discussed more
and which ended up with the session idea [1]
Having entry together with return probe for given function is common
use case for tetragon, bpftrace and most likely for others.
At the moment if we want both entry and return probe to execute bpf
program we need to create two (entry and return probe) links. The link
for return probe creates extra entry probe to setup the return probe.
The extra entry probe execution could be omitted if we had a way to
use just single link for both entry and exit probe.
In addition the possibility to control the return program execution
and sharing data within entry and return probe allows for other use
cases.
v2 changes:
- renamed BPF_TRACE_KPROBE_MULTI_SESSION to BPF_TRACE_KPROBE_SESSION
[Andrii]
- use arrays for results in selftest [Andrii]
- various small selftests and libbpf changes [Andrii]
- moved the verifier cookie setup earlier in check_kfunc_call [Andrii]
- added acks

Introduce a new compatible support in the Amlogic PWM driver.
The PWM HW is actually the same for all SoCs supported so far. A specific
compatible is needed only because the clock sources of the PWMs are
hard-coded in the driver.
It is better to have the clock source described in DT but this changes the
bindings so a new compatible must be introduced.
When all supported platform have migrated to the new compatible, support
for the legacy ones may be removed from the driver.
The addition of this new compatible makes the old ones obsolete, as
described in the DT documentation.
Adding a callback to setup the clock will also make it easier to add
support for the new PWM HW found in a1, s4, c3 and t7 SoC families.

stm32_pwm_config() took the duty_cycle and period values with the type
int, however stm32_pwm_apply() passed u64 values there. Expand the
function parameters to u64 to not discard relevant bits and adapt the
calculations to the wider type.
To ensure the calculations won't overflow, check in .probe() the input
clk doesn't run faster than 1 GHz.

While mathematically it's ok to calculate the number of cyles for the
duty cycle as:
duty_cycles = period_cycles * duty_ns / period_ns
this doesn't always give the right result when doing integer math. This
is best demonstrated using an example: With the input clock running at
208877930 Hz a request for duty_cycle = 383 ns and period = 49996 ns
results in
period_cycles = clkrate * period_ns / NSEC_PER_SEC = 10443.06098828
Now calculating duty_cycles with the above formula gives:
duty_cycles = 10443.06098828 * 383 / 49996 = 80.00024719
However with period_cycle truncated to an integer results in:
duty_cycles = 10443 * 383 / 49996 = 79.99977998239859
So while a value of (a little more than) 80 would be the right result,
only 79 is used here. The problem here is that 14443 is a rounded result
that should better not be used to do further math. So to fix that use
the exact formular similar to how period_cycles is calculated.

After assigning chip = pwm->chip; the compiler is free to assume that
pwm is non-NULL and so can optimize out the check for pwm against NULL.
While it's probably a programming error to pass a NULL pointer to
pwm_put() this shouldn't be dropped without careful consideration and
wasn't intended.
So assign chip only after the NULL check.

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.

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.

If a DMI table entry is shorter than 4 bytes, it is invalid. Due to
how DMI table parsing works, it is impossible to safely recover from
such an error, so we have to stop decoding the table.

platform/x86: ISST: Add Grand Ridge to HPM CPU list
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.
