This implements operations related to IDs for the loopback-ism device.
loopback-ism uses an Extended GID that is a 128-bit GID instead of the
existing ISM 64-bit GID, and uses the CHID defined with the reserved
value 0xFFFF.

This introduces a kind of Emulated-ISM device named loopback-ism for
SMCv2.1. The loopback-ism device is currently exclusive for SMC usage,
and aims to provide an SMC shortcut for sockets within the same kernel,
leading to improved intra-OS traffic performance. Configuration of this
feature is managed through the config SMC_LO.

The struct 'ism_client' is specialized for s390 platform firmware ISM.
So replace it with 'void' to make SMCD DMB registration helper generic
for both Emulated-ISM and existing ISM.

strncpy() is deprecated for use on NUL-terminated destination strings
[1] and as such we should prefer more robust and less ambiguous string
interfaces.
This kernel config option is simply assigned with the resume_file
buffer. It should be NUL-terminated but not necessarily NUL-padded as
per its further usage with other string apis:
| static int __init find_resume_device(void)
| {
| if (!strlen(resume_file))
| return -ENOENT;
|
| pm_pr_dbg("Checking hibernation image partition %s\n", resume_file);
Use strscpy() [2] as it guarantees NUL-termination on the destination
buffer. Specifically, use the new 2-argument version of strscpy()
introduced in Commit e6584c3964f2f ("string: Allow 2-argument
strscpy()").

[BUG]
When running generic/287, the following file extent items can be
generated:
item 16 key (258 EXTENT_DATA 2682880) itemoff 15305 itemsize 53
generation 9 type 1 (regular)
extent data disk byte 1378414592 nr 462848
extent data offset 0 nr 462848 ram 2097152
extent compression 0 (none)
Note that file extent item is not a compressed one, but its ram_bytes is
way larger than its disk_num_bytes.
According to btrfs on-disk scheme, ram_bytes should match disk_num_bytes
if it's not a compressed one.
[CAUSE]
Since commit b73a6fd1b1ef ("btrfs: split partial dio bios before
submit"), for partial dio writes, we would split the ordered extent.
However the function btrfs_split_ordered_extent() doesn't update the
ram_bytes even it has already shrunk the disk_num_bytes.
Originally the function btrfs_split_ordered_extent() is only introduced
for zoned devices in commit d22002fd37bd ("btrfs: zoned: split ordered
extent when bio is sent"), but later commit b73a6fd1b1ef ("btrfs: split
partial dio bios before submit") makes non-zoned btrfs affected.
Thankfully for un-compressed file extent, we do not really utilize the
ram_bytes member, thus it won't cause any real problem.
[FIX]
Also update btrfs_ordered_extent::ram_bytes inside
btrfs_split_ordered_extent().
Fixes: d22002fd37bd ("btrfs: zoned: split ordered extent when bio is sent")

This is an effort to get rid of all multiplications from allocation
functions in order to prevent integer overflows [1][2].
As the "ids" variable is a pointer to "struct sctp_assoc_ids" and this
structure ends in a flexible array:
struct sctp_assoc_ids {
[...]
sctp_assoc_t gaids_assoc_id[];
};
the preferred way in the kernel is to use the struct_size() helper to
do the arithmetic instead of the calculation "size + size * count" in
the kmalloc() function.
Also, refactor the code adding the "ids_size" variable to avoid sizing
twice.
This way, the code is more readable and safer.
This code was detected with the help of Coccinelle, and audited and
modified manually.

To enhance functionality, we now support reporting statistics through
the netdev-generic netlink (netdev-genl) queue stats interface. However,
this does not extend to all statistics, so a new field, qstat_offset,
has been introduced. This field determines which statistics should be
reported via netdev-genl queue stats.
Given that queue stats are retrieved individually per queue, it's
necessary for the virtnet_get_hw_stats() function to be capable of
fetching statistics for a specific queue.
As the document https://docs.kernel.org/next/networking/statistics.html#notes-for-driver-authors
We should not duplicate the stats which get reported via the netlink API in
ethtool. If the stats are for queue stat, that will not be reported by
ethtool -S.

The key size of ethtool -S is controlled by this macro.
ETH_GSTRING_LEN 32
That includes the \0 at the end. So the max length of the key name must
is 31. But the length of the prefix "rx_queue_0_" is 11. If the queue
num is larger than 10, the length of the prefix is 12. So the
key name max is 19. That is too short. We will introduce some keys
such as "gso_packets_coalesced". So we should change the prefix
to "rx0_".

- Laurent converts the Raspberry Pi firmware DT binding to YAML, updates
the firmware driver to use the proper 'struct device' reference for
DMA mappings and drops unneeded properties from the DT node and
finishes by removing the duplicate firmware-clocks property to
bcm2835-rpi.dtsi. He also added support for the CAM1 camera interface
regulator.
- Uwe adds a pinctrl-based multiplexing description to allow the use of
I2C0 pins to allow usage between the 40-pin Raspberry Pi header and
the CSI and DSI connectors. He then describes the PCF85063 RTC device
available on the CM4 I/O board making use of that pinctrl-based
muxing.
- Arinc updates the Asus RT-AC3100 and RT-AC88U DTs to have proper LED
colors and function properties, NVMEM MAC addresses and removes
duplicates and unnecessary properties and does a few Device Tree
cleanups.. He then adds support for the Asus RT-AC3200 (BCM4709-based)
and RT-AC3500 routers.
- Jean-Michel adds DT nodes for the CSI Unicam camera interfaces on the
Raspberry Pi 4 / BCM2711 SoCs
- Florian adds support for the Ethernet LEDs on Raspberry Pi 4 B and
Raspberry Pi 4 CM boards.

With 'iommu=off' on the kernel command line and x2APIC enabled by the BIOS
the code which disables the x2APIC triggers an unchecked MSR access error:
RDMSR from 0x802 at rIP: 0xffffffff94079992 (native_apic_msr_read+0x12/0x50)
This is happens because default_acpi_madt_oem_check() selects an x2APIC
driver before the x2APIC is disabled.
When the x2APIC is disabled because interrupt remapping cannot be enabled
due to 'iommu=off' on the command line, x2apic_disable() invokes
apic_set_fixmap() which in turn tries to read the APIC ID. This triggers
the MSR warning because x2APIC is disabled, but the APIC driver is still
x2APIC based.
Prevent that by adding an argument to apic_set_fixmap() which makes the
APIC ID read out conditional and set it to false from the x2APIC disable
path. That's correct as the APIC ID has already been read out during early
discovery.

Russell King says:
====================
net: dsa: microchip: use phylink_mac_ops for ksz driver
This four patch series switches the Microchip KSZ DSA driver to use
phylink_mac_ops support, and for this one we go a little further
beyond a simple conversion. This driver has four distinct cases:
lan937x
ksz9477
ksz8
ksz8830
Three of these cases are handled by shimming the existing DSA calls
through ksz_dev_ops, and the final case is handled through a
conditional in ksz_phylink_mac_config(). These can all be handled
with separate phylink_mac_ops.
To get there, we do a progressive conversion.
Patch 1 removes ksz_dev_ops' phylink_mac_config() method which is
not populated in any of the arrays - and is thus redundant.
Patch 2 switches the driver to use a common set of phylink_mac_ops
for all cases, doing the simple conversion to avoid the DSA shim.
Patch 3 pushes the phylink_mac_ops down to the first three classes
(lan937x, ksz9477, ksz8) adding an appropriate pointer to the
phylink_mac_ops to struct ksz_chip_data, and using that to
populate DSA's ds->phylink_mac_ops pointer. The difference between
each of these are the mac_link_up() method. mac_config() and
mac_link_down() remain common between each at this stage.
Patch 4 splits out ksz8830, which needs different mac_config()
handling, and thus means we have a difference in mac_config()
methods between the now four phylink_mac_ops structures.
Build tested only, with additional -Wunused-const-variable flag.

Commit 47ea0ddb1f56 ("platform/chrome: cros_ec_lpc: Separate host
command and irq disable") re-ordered the resume sequence. Before that
change, cros_ec resume sequence is:
1) Enable IRQ
2) Send resume event
3) Handle events during suspend
After commit 47ea0ddb1f56 ("platform/chrome: cros_ec_lpc: Separate host
command and irq disable"), cros_ec resume sequence is:
1) Enable IRQ
2) Handle events during suspend
3) Send resume event.
This re-ordering leads to delayed handling of any events queued between
items 2) and 3) with the updated sequence. Also in certain platforms, EC
skips triggering interrupt for certain events eg. mkbp events until the
resume event is received. Such events are stuck in the host event queue
indefinitely. This change puts back the original order to avoid any
delay in handling the pending events.

Add a selftests validating that it's possible to have some struct_ops
callback set declaratively, then disable it (by setting to NULL)
programmatically. Libbpf should detect that such program should
not be loaded. Otherwise, it will unnecessarily fail the loading
when the host kernel does not have the type information.

If struct_ops has one of program callbacks set declaratively and host
kernel is old and doesn't support this callback, libbpf will allow to
load such struct_ops as long as that callback was explicitly nulled-out
(presumably through skeleton). This is all working correctly, except we
won't reset corresponding program slot to NULL before bailing out, which
will lead to libbpf not detecting that BPF program has to be not
auto-loaded. Fix this by unconditionally resetting corresponding program
slot to NULL.

Inclusion of the header linux/btf_ids.h relies on indirect inclusion of
the header linux/types.h. Including it directly on the top level helps
to avoid potential problems if linux/types.h hasn't been included
before.
The main motivation to introduce this it is to avoid similar problems that
have shown up in the bpftool where GNU libc indirectly pulls
linux/types.h causing compile error of the form:
error: unknown type name 'u32'
u32 cnt;
^~~

The strdup() function returns a pointer to a new string which is a
duplicate of the string "input". Memory for the new string is obtained
with malloc(), and need to be freed with free().
This patch adds these missing "free(input)" in parse_stats() to avoid
memory leak in veristat.c.
