kzalloc() is a memory allocation function which can return NULL when
some internal memory errors happen. So it is better to check it to
prevent potential wrong memory access.

Update IDT VersaClock 5 driver to support 5P49V6975. The 5P49V6975 is a
member of the VersaClock 6E family and supports four fractional dividers
(FODs), five clock outputs and an internal oscillator.

In order to enable namespaces or any sort of isolation within
user_events the register lock and pages need to be broken up into
groups. Each event and file now has a group pointer which stores the
actual pages to map, lookup data and synchronization objects.
This only enables a single group that maps to init_user_ns, as IMA
namespace has done. This enables user_events to start the work of
supporting namespaces by walking the namespaces up to the init_user_ns.
Future patches will address other user namespaces and will align to the
approaches the IMA namespace uses.

Pull RCU updates from Paul McKenney:
- Documentation updates.
This is the first in a series from an ongoing review of the RCU
documentation. "Why are people thinking -that- about RCU? Oh. Because
that is an entirely reasonable interpretation of its documentation."
- Miscellaneous fixes.
- Improved memory allocation and heuristics.
- Improve rcu_nocbs diagnostic output.
- Add full-sized polled RCU grace period state values.
These are the same size as an rcu_head structure, which is double
that of the traditional unsigned long state values that may still be
obtained from et_state_synchronize_rcu(). The added size avoids
missing overlapping grace periods. This benefit is that call_rcu()
can be replaced by polling, which can be attractive in situations
where RCU-protected data is aged out of memory.
Early in the series, the size of this state value is three unsigned
longs. Later in the series, the fastpaths in synchronize_rcu() and
synchronize_rcu_expedited() are reworked to permit the full state to
be represented by only two unsigned longs. This reworking slows these
two functions down in SMP kernels running either on single-CPU
systems or on systems with all but one CPU offlined, but this should
not be a significant problem. And if it somehow becomes a problem in
some yet-as-unforeseen situations, three-value state values can be
provided for only those situations.
Finally, a pair of functions named same_state_synchronize_rcu() and
same_state_synchronize_rcu_full() allow grace-period state values to
be compared for equality. This permits users to maintain lists of
data structures having the same state value, removing the need for
per-data-structure grace-period state values, thus decreasing memory
footprint.
- Polled SRCU grace-period updates, including adding tests to
rcutorture and reducing the incidence of Tiny SRCU grace-period-state
counter wrap.
- Improve Tasks RCU diagnostics and quiescent-state detection.
* tag 'rcu.2022.09.30a' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu: (55 commits)

Masami has been maintaining kprobes for a while now and that code has
been an integral part of tracing. He has also been an excellent reviewer
of all the tracing code and contributor as well.
The tracing subsystem needs another active maintainer to keep it running
smoothly, and I do not know anyone more qualified for the job than Masami.
Ingo has also told me that he has not been active in the tracing code for
some time and said he could be removed from the TRACING portion of the
MAINTAINERS file.

'commit c193707dde77 ("tracing: Remove code which merges duplicates")'
This commit removed the code which merges duplicates in detect_dups(),
but forgot to delete the variable 'dups' which used to merge
duplicates in the loop.
Now only 'total_dups' is needed, remove 'dups' for clean code.

Since I'm actively involved in a number of arch bits that intersect
ftrace (e.g. the actual arch implementation on arm64, stacktracing,
entry management, and general instrumentation safety), add myself as a
reviewer of the core ftrace code so that I have the change to catch any
potential problems early.
I spoke with Steven about this at LPC, and it seemed to make sense to
add me as a reviewer.

ASoC: Updates for v6.1
This has been a very quiet release for the core but quite a busy one for
drivers with a big crop of new drivers and lots of feature additions and
fixes to existing ones:
- A new string helper parse_int_array_user().
- Improvements to the SOF IPC4 code, especially around trace.
- Support for AMD Rembrant DSPs, AMD Pink Sardine ACP 6.2, Apple Silcon
systems, Everest ES8326, Intel Sky Lake and Kaby Lake, MediaTek
MT8186 support, NXP i.MX8ULP DSPs, Qualcomm SC8280XP, SM8250 and SM8450
and Texas Instruments SRC4392
There is a conflict with the conversion of I2C remove functions to void
in the cs42l42 driver which is fairly straightforward to resolve but
should be highlighted to Linus.

Christophe Leroy reported a ~80ms latency spike
happening at first TCP connect() time.
This is because __inet_hash_connect() uses get_random_once()
to populate a perturbation table which became quite big
after commit 4c2c8f03a5ab ("tcp: increase source port perturb table to 2^16")
get_random_once() uses DO_ONCE(), which block hard irqs for the duration
of the operation.
This patch adds DO_ONCE_SLOW() which uses a mutex instead of a spinlock
for operations where we prefer to stay in process context.
Then __inet_hash_connect() can use get_random_slow_once()
to populate its perturbation table.
Fixes: 4c2c8f03a5ab ("tcp: increase source port perturb table to 2^16")

above the wwan_register_ops call. This also makes the order of

Subbaraya Sundeep says:
====================
net: Introduce macsec hardware offload for cn10k platform
CN10K-B and CNF10K-B variaints of CN10K silicon has macsec block(MCS)
to encrypt and decrypt packets at MAC/hardware level. This block is a
global resource with hardware resources like SecYs, SCs and SAs
and is in between NIX block and RPM LMAC. CN10K-B silicon has only
one MCS block which receives packets from all LMACS whereas
CNF10K-B has seven MCS blocks for seven LMACs. Both MCS blocks are
similar in operation except for few register offsets and some
configurations require writing to different registers. This patchset
introduces macsec hardware offloading support. AF driver manages hardware
resources and PF driver consumes them when macsec hardware offloading
is needed.
Patch 1 adds basic pci driver for both CN10K-B and CNF10K-B
silicons and initializes hardware block.
Patches 2 and 3 adds mailboxes to init, reset and manage
resources of the MCS block
Patch 4 adds a low priority rule in MCS TCAM so that the
traffic which do not need macsec processing can be sent/received
Patch 5 adds macsec stats collection support
Patch 6 adds interrupt handling support and any event in which
AF consumer is interested can be notified via mbox notification
Patch 7 adds debugfs support which helps in debugging packet
path
Patch 8 introduces macsec hardware offload feature for
PF netdev driver.
v3 changes:
Fixed clang and sparse warnings
v2 changes:
Fix build error by changing #ifdef CONFIG_MACSEC to
#if IS_ENABLED(CONFIG_MACSEC)

This patch introduces the macsec offload feature to cn10k
PF netdev driver. The macsec offload ops like adding, deleting
and updating SecYs, SCs, SAs and stats are supported. XPN support
will be added in later patches. Some stats use same counter in hardware
which means based on the SecY mode the same counter represents different
stat. Hence when SecY mode/policy is changed then snapshot of current
stats are captured. Also there is no provision to specify the unique
flow-id/SCI per packet to hardware hence different mac address needs to
be set for macsec interfaces.

Hardware triggers an interrupt for events like PN wrap to zero,
PN crosses set threshold. This interrupt is received
by the MCS_AF. MCS AF then finds the PF/VF to which SA is mapped
and notifies them using mcs_intr_notify mbox message.
PF/VF using mcs_intr_cfg mbox can configure the list
of interrupts for which they want to receive the
notification from AF.

This patch optimizes the RX buffer management by using the page
pool. The purpose for this change is to prepare for the following
XDP support. The current driver uses one frame per page for easy
management.
Added __maybe_unused attribute to the following functions to avoid
the compiling warning. Those functions will be removed by a separate
patch once this page pool solution is accepted.
- fec_enet_new_rxbdp
- fec_enet_copybreak
The following are the comparing result between page pool implementation
and the original implementation (non page pool).
--- small packet (64 bytes) testing are almost the same
--- no matter what the implementation is
--- on both i.MX8 and i.MX6SX platforms.
