The MPTCP receive path is hooked only into the TCP slow-path.
The DSS presence allows plain MPTCP traffic to hit that
consistently.
Since commit e1ff9e82e2 ("net: mptcp: improve fallback to TCP"),
when an MPTCP socket falls back to TCP, it can hit the TCP receive
fast-path, and delay or stop triggering the event notification.
Address the issue explicitly disabling the header prediction
for MPTCP sockets.

Normally, if a reset fails due to failover or other communication error
there is another reset (eg: FAILOVER) in the queue and we would process
that reset. But if we are unable to communicate with PHYP or VIOS after
H_FREE_CRQ, there would be no other resets in the queue and the adapter
would be in an undefined state even though it was in the OPEN state
earlier. While starting the reset we set the carrier to off state so
we won't even get the timeout resets.
If the last queued reset fails, retry it as a hard reset (after the
usual 60 second settling time).

ptp: support virtual clocks and timestamping
Current PTP driver exposes one PTP device to user which binds network
interface/interfaces to provide timestamping. Actually we have a way
utilizing timecounter/cyclecounter to virtualize any number of PTP
clocks based on a same free running physical clock for using.
The purpose of having multiple PTP virtual clocks is for user space
to directly/easily use them for multiple domains synchronization.
user
space: ^ ^
| SO_TIMESTAMPING new flag: | Packets with
| SOF_TIMESTAMPING_BIND_PHC | TX/RX HW timestamps
v v
+--------------------------------------------+
sock: | sock (new member sk_bind_phc) |
+--------------------------------------------+
^ ^
| ethtool_get_phc_vclocks | Convert HW timestamps

v v
+--------------+--------------+--------------+
vclock: | ptp1 | ptp2 | ptpN |
+--------------+--------------+--------------+
pclock: | ptp0 free running |
+--------------------------------------------+
The block diagram may explain how it works. Besides the PTP virtual
clocks, the packet HW timestamp converting to the bound PHC is also
done in sock driver. For user space, PTP virtual clocks can be
created via sysfs, and extended SO_TIMESTAMPING API (new flag
SOF_TIMESTAMPING_BIND_PHC) can be used to bind one PTP virtual clock
for timestamping.
The test tool timestamping.c (together with linuxptp phc_ctl tool) can
be used to verify:

This patch is to extend SO_TIMESTAMPING API to support

SOF_TIMESTAMPING_BIND_PHC. When PTP virtual clocks are
in use, user space can configure to bind one for

If one entered io_req_task_work_add() not seeing PF_EXITING, it will set
a ->task_state bit and try task_work_add(), which may fail by that
moment. If that happens the function would try to cancel the request.
However, in a meanwhile there might come other io_req_task_work_add()
callers, which will see the bit set and leave their requests in the
list, which will never be executed.
Don't propagate an error, but clear the bit first and then fallback
all requests that we can splice from the list. The callback functions
have to be able to deal with PF_EXITING, so poll and apoll was modified
via changing io_poll_rewait().

When task_work_add() fails, we use ->exit_task_work to queue the work.
That will be run only in the cancellation path, which happens either
when the ctx is dying or one of tasks with inflight requests is exiting
or executing. There is a good chance that such a request would just get
stuck in the list potentially hodling a file, all io_uring rsrc
recycling or some other resources. Nothing terrible, it'll go away at
some point, but we don't want to lock them up for longer than needed.

In perf annotate, when 's' is pressed on a line containing source code,
it shows the message "Only available for assembly lines".
This patch gets rid of the error, moving the cursr to the next available
asm line (or the closest previous one if no asm line is found moving
forwards), before hiding source code lines.
Changes in v2:
- handle case of no asm line found in
annotate_browser__find_next_asm_line by returning NULL and
handling error in caller.

filter_event_early() can be more than 30% faster than filter_event()
because it is called before internal filtering. In other respects it
is the same as filter_event(), except that it will be passed events
that have yet to be filtered out.

In some cases, users want to filter very large amounts of data (e.g.
from AUX area tracing like Intel PT) looking for something specific.
While scripting such as Python can be used, Python is 10 to 20 times
slower than C. So define a C API so that custom filters can be written
and loaded.

Zhihao sent a patch but it made llvm__compile_bpf() return what
asprintf() returns on error, which is just -1, but since this function
returns -errno, fix it by returning -ENOMEM for this case instead.
Fixes: cb76371441 ("perf llvm: Allow passing options to llc ...")
Fixes: 5eab5a7ee0 ("perf llvm: Display eBPF compiling command ...")
