In the current code for powernv_add_idle_states, there is a lot of code
duplication while initializing an idle state in powernv_states table.
Add an inline helper function to populate the powernv_states[] table

Add necessary plumbing at the slave network device level to have switch
drivers implement ndo_setup_tc() and most particularly the cls_matchall
classifier. We add support for two switch operations:
port_add_mirror and port_del_mirror() which configure, on a per-port
basis the mirror parameters requested from the cls_matchall classifier.
Code is largely borrowed from the Mellanox Spectrum switch driver.

Packets arriving in a VRF currently are delivered to UDP sockets that
aren't bound to any interface. TCP defaults to not delivering packets
arriving in a VRF to unbound sockets. IP route lookup and socket
transmit both assume that unbound means using the default table and
UDP applications that haven't been changed to be aware of VRFs may not
function correctly in this case since they may not be able to handle
overlapping IP address ranges, or be able to send packets back to the
original sender if required.
So add a sysctl, udp_l3mdev_accept, to control this behaviour with it
being analgous to the existing tcp_l3mdev_accept, namely to allow a
process to have a VRF-global listen socket. Have this default to off
as this is the behaviour that users will expect, given that there is
no explicit mechanism to set unmodified VRF-unaware application into a
default VRF.

Since commit f3b0946d62 ("genirq/msi: Make sure PCI MSIs are
activated early"), we can end-up activating a PCI/MSI twice (once
at allocation time, and once at startup time).
This is normally of no consequences, except that there is some
HW out there that may misbehave if activate is used more than once
(the GICv3 ITS, for example, uses the activate callback
to issue the MAPVI command, and the architecture spec says that
"If there is an existing mapping for the EventID-DeviceID
combination, behavior is UNPREDICTABLE").
While this could be worked around in each individual driver, it may
make more sense to tackle the issue at the core level. In order to
avoid getting in that situation, let's have a per-interrupt flag
to remember if we have already activated that interrupt or not.

For IR wakeup, a driver has to program the hardware to wakeup at a
specific IR sequence, so it makes no sense to allow multiple wakeup
protocols to be selected. In the same manner the sysfs interface only
allows one scancode to be provided.
In addition, we need to know the specific variant of the protocol.
In short, these changes are made to the wakeup_protocols sysfs entry:
- list all the protocol variants rather than the protocol groups,
e.g. "nec nec-x nec-32" rather than just "nec".
- only allow one protocol variant to be selected rather than multiple
- wakeup_filter can only be set once a protocol has been selected in
wakeup_protocols.
This is an API change, however the only user of this API is the img-ir,
but the wakeup code was never merged to mainline, so it was never used.

cpuctx->unique_pmu == cpuctx->pmu in non-software task contexts since they
have only one pmu per cpuctx. Since perf_pmu_sched_task() is only called in
hw contexts, this patch replaces cpuctx->unique_pmu by cpuctx->pmu in it.

This patch follows from a conversation in CQM/CMT's last series about
speeding up the context switch for cgroup events:
https://patchwork.kernel.org/patch/9478617/
This is a low-hanging fruit optimization. It replaces the iteration over
the "pmus" list in cgroup switch by an iteration over a new list that
contains only cpuctxs with at least one cgroup event.
This is necessary because the number of PMUs have increased over the years
e.g modern x86 server systems have well above 50 PMUs.
The iteration over the full PMU list is unneccessary and can be costly in
heavy cache contention scenarios.
Below are some instrumentation measurements with 10, 50 and 90 percentiles
of the total cost of context switch before and after this optimization for
a simple array read/write microbenchark.
Contention
Level Nr events Before (us) After (us) Median
L2 L3 types (10%, 50%, 90%) (10%, 50%, 90% Speedup
--------------------------------------------------------------------------
Low Low 1 (1.72, 2.42, 5.85) (1.35, 1.64, 5.46) 29%
High Low 1 (2.08, 4.56, 19.8) (1720, 2.20, 13.7) 51%
High High 1 (2.86, 10.4, 12.7) (2.54, 4.32, 12.1) 58%
Low Low 2 (1.98, 3.20, 6.89) (1.68, 2.41, 8.89) 24%
High Low 2 (2.48, 5.28, 22.4) (2150, 3.69, 14.6) 30%
High High 2 (3.32, 8.09, 13.9) (2.80, 5.15, 13.7) 36%
where:
1 event type = cycles
2 event types = cycles,intel_cqm/llc_occupancy/
Contention L2 Low: workset < L2 cache size.
High: " >> L2 " " .
Contention L3 Low: workset of task on all sockets < L3 cache size.
High: " " " " " " >> L3 " " .
Median Speedup is (50%ile Before - 50%ile After) / 50%ile Before
Unsurprisingly, the benefits of this optimization decrease with the number
of cpuctxs with a cgroup events, yet, is never detrimental.

I was under the misconception that the sysfs dev stuff can be fully
set up, and then registered all in one step with device_add. That's
true for properties and property groups, but not for parents and child
devices. Those must be fully registered before you can register a
child.
Add a bit of tracking to make sure that asynchronous mst connector
hotplugging gets this right. For consistency we rely upon the implicit
barriers of the connector->mutex, which is taken anyway, to ensure
that at least either the connector or device registration call will
work out.
Mildly tested since I can't reliably reproduce this on my mst box

This patch adds devm_alloc_etherdev_mqs function and devm_alloc_etherdev
macro. These can be used for simpler netdev allocation without having to
care about calling free_netdev.
Thanks to this change drivers, their error paths and removal paths may
get simpler by a bit.

Add two stats in SCM_TIMESTAMPING_OPT_STATS:
TCP_NLA_DATA_SEGS_OUT: total data packets sent including retransmission
TCP_NLA_TOTAL_RETRANS: total data packets retransmitted
The names are picked to be consistent with corresponding fields in
TCP_INFO. This allows applications that are using the timestamping
API to measure latency stats to also retrive retransmission rate
of application write.
