There will likely be more info that we need to store in struct
pidfs_attr. We need to make sure that some of the information such as
exit info or coredump info that consists of multiple bits is either
available completely or not at all, but never partially. Currently we
use a pointer that we assign to. That doesn't scale. We can't waste a
pointer for each mulit-part information struct we want to expose. Use a
bitmask instead.

Some of the future fields in struct pidfd_info can be optional. If the
kernel has nothing to emit in that field, then it doesn't set the flag
in the reply. This presents a problem: There is currently no way to know
what mask flags the kernel supports since one can't always count on them
being in the reply.
Add a new PIDFD_INFO_SUPPORTED_MASK flag and field that the kernel can
set in the reply. Userspace can use this to determine if the fields it
requires from the kernel are supported. This also gives us a way to
deprecate fields in the future, if that should become necessary.

When PIDFD_INFO_COREDUMP is requested we raise it unconditionally in the
returned mask even if no coredump actually did take place. This was
done because we assumed that the later check whether ->coredump_mask as
non-zero detects that it is zero and then retrieves the dumpability
settings from the task's mm. This has issues though becuase there are
tasks that might not have any mm. Also it's just not very cleanly

Currently if a -ENOMEM from smc_wr_alloc_link_mem() is handled by
giving up and going the way of a TCP fallback. This was reasonable
before the sizes of the allocations there were compile time constants
and reasonably small. But now those are actually configurable.
So instead of giving up, keep retrying with half of the requested size
unless we dip below the old static sizes -- then give up! In terms of
numbers that means we give up when it is certain that we at best would
end up allocating less than 16 send WR buffers or less than 48 recv WR
buffers. This is to avoid regressions due to having fewer buffers
compared the static values of the past.
Please note that SMC-R is supposed to be an optimisation over TCP, and
falling back to TCP is superior to establishing an SMC connection that
is going to perform worse. If the memory allocation fails (and we
propagate -ENOMEM), we fall back to TCP.
Preserve (modulo truncation) the ratio of send/recv WR buffer counts.

- The 2nd one is triggered by the "Kernel panic - not syncing:
Hard LOCKUP" line printed with NBCON_PRIO_PANIC.
There are more than 2500 lines, at about 240kB, emitted between
the takeover and the 1st "WARNING" line in the emergency context.
This amount of pending messages had to be flushed by
nbcon_atomic_flush_pending() when WARN() printed its first line.
The atomic flush was holding the nbcon console context for too long so
that it triggered hard lockup on the CPU running the printk kthread
"pr/ttyS0". The kthread needed to reacquire the console ownership
for restoring the original serial port state in serial8250_console_write().
Prevent the hardlockup by releasing the nbcon console ownership after
each emitted record.
Note that __nbcon_atomic_flush_pending_con() used to hold the console
ownership all the time because it blocked the printk kthread. Otherwise
the kthread tried to flush the messages in parallel which caused repeated
takeovers and more replayed messages.
It is not longer a problem because the repeated takeovers are blocked
by the counter of emergency contexts, see nbcon_cpu_emergency_cnt.

In emergency contexts, printk() tries to flush messages directly even
on nbcon consoles. And it is allowed to takeover the console ownership
and interrupt the printk kthread in the middle of a message.
Only one takeover and one repeated message should be enough in most
situations. The first emergency message flushes the backlog and printk
kthreads get to sleep. Next emergency messages are flushed directly
and printk() does not wake up the kthreads.
However, the one takeover is not guaranteed. Any printk() in normal
context on another CPU could wake up the kthreads. Or a new emergency
message might be added before the kthreads get to sleep. Note that
the interrupted .write_thread() callbacks usually have to call
nbcon_reacquire_nobuf() and restore the original device setting
before checking for pending messages.
The risk of the repeated takeovers will be even bigger because
__nbcon_atomic_flush_pending_con is going to release the console
ownership after each emitted record. It will be needed to prevent
hardlockup reports on other CPUs which are busy waiting for
the context ownership, for example, by nbcon_reacquire_nobuf() or
__uart_port_nbcon_acquire().
The repeated takeovers break the output, for example:

A more robust solution is to block the printk kthread entirely whenever
*any* CPU enters an emergency context. This ensures that critical messages
can be flushed without contention from the normal, non-atomic printing
path.

The GSO segmentation functions for ESP tunnel mode
(xfrm4_tunnel_gso_segment and xfrm6_tunnel_gso_segment) were
determining the inner packet's L2 protocol type by checking the static
x->inner_mode.family field from the xfrm state.
This is unreliable. In tunnel mode, the state's actual inner family
could be defined by x->inner_mode.family or by
x->inner_mode_iaf.family. Checking only the former can lead to a
mismatch with the actual packet being processed, causing GSO to create
segments with the wrong L2 header type.
This patch fixes the bug by deriving the inner mode directly from the
packet's inner protocol stored in XFRM_MODE_SKB_CB(skb)->protocol.
Instead of replicating the code, this patch modifies the
xfrm_ip2inner_mode helper function. It now correctly returns
&x->inner_mode if the selector family (x->sel.family) is already
specified, thereby handling both specific and AF_UNSPEC cases
appropriately.
With this change, ESP GSO can use xfrm_ip2inner_mode to get the
correct inner mode. It doesn't affect existing callers, as the updated
logic now mirrors the checks they were already performing externally.

In the output path, xfrm_dev_offload_ok and xfrm_get_inner_ipproto
need to determine the protocol family of the inner packet (skb) before
it gets encapsulated.
In xfrm_dev_offload_ok, the code checked x->inner_mode.family. This is
unreliable because, for states handling both IPv4 and IPv6, the
relevant inner family could be either x->inner_mode.family or
x->inner_mode_iaf.family. Checking only the former can lead to a
mismatch with the actual packet being processed.
In xfrm_get_inner_ipproto, the code checked x->outer_mode.family. This
is also incorrect for tunnel mode, as the inner packet's family can be
different from the outer header's family.
At both of these call sites, the skb variable holds the original inner
packet. The most direct and reliable source of truth for its protocol
family is its destination entry. This patch fixes the issue by using
skb_dst(skb)->ops->family to ensure protocol-specific headers are only
accessed for the correct packet type.

Based on available evidence, the USB ID 4c4a:4155 used by multiple
devices has been attributed to Jieli. The commit 1a8953f4f7
("HID: Add IGNORE quirk for SMARTLINKTECHNOLOGY") affected touchscreen
functionality. Added checks for manufacturer and serial number to
maintain microphone compatibility, enabling both devices to function
properly.

Subbaraya Sundeep says:
====================
Add CN20K NIX and NPA contexts
The hardware contexts of blocks NIX and NPA in CN20K silicon are
different than that of previous silicons CN10K and CN9XK. This
patchset adds the new contexts of CN20K in AF and PF drivers.
A new mailbox for enqueuing contexts to hardware is added.
Patch 1 simplifies context writing and reading by using max context
size supported by hardware instead of using each context size.
Patch 2 and 3 adds NIX block contexts in AF driver and extends
debugfs to display those new contexts
Patch 4 and 5 adds NPA block contexts in AF driver and extends
debugfs to display those new contexts
Patch 6 omits NDC configuration since CN20K NPA does not use NDC
for caching its contexts
Patch 7 and 8 uses the new NIX and NPA contexts in PF/VF driver.
Patch 9, 10 and 11 are to support more bandwidth profiles present in
CN20K for RX ratelimiting and to display new profiles in debugfs

Receive queue points to a bandwidth profile for rate limiting.
Since cn20k has additional bandwidth profiles use them
too while mapping receive queue to bandwidth profile.

CN20K has 16k of leaf profiles, 2k of middle profiles and
256 of top profiles. This patch modifies existing receive
queue and bandwidth profile context structures to accommodate
additional profiles of cn20k.

For cn20k, NPA block doesn't use the general purpose
NDC (Near Coprocessor Bus Data cache Unit) for caching,
hence skip the NDC related operations.
Also refactor NDC configuration code to a helper function.

have nothing to do within the SoC node.
Extract it from the SoC node and let IPs nodes in the Soc node.

* sti-controller -> display-controller
* sti-tvout -> encoder
