In the arm platform, we do not have the "CPU family" as X86.
In the linux kernel, it is hardcode to set the "CPU architecuture:8"
which should be changed for arm v9 in future.
This patch adds "bios_family" field, which we can get from the DMI table.
In the ampere Altra platform, we can get the new lscpu output:

The patch :367c85c47286 ("lscpu: use SMBIOS tables on ARM for lscpu")
relies on the existence of "/sys/firmware/dmi/entries/4-0/raw",
which may not exist in standard linux kernel.
But "/sys/firmware/dmi/tables/DMI" should exist and can provide the required
processor information.
This patch uses "/sys/firmware/dmi/tables/DMI"
to get the processor information:

Double-semicolon at the end of the option line results in description
being indented extra tab to the right. Replacing them with double-colons

The tree of *parent* and *owner* could be forests because *lsns*
cannot track a namespace having no process.
This change tries interpolating the missing namespaces by calling
ioctl(NS_GET_PARENT) and ioctl(NS_GET_USERNS) recursively.
The original output for -Tparent:
# ./lsns -Tparent
NS TYPE NPROCS PID USER COMMAND
4026531837 user 404 1 root /usr/lib/systemd/sy
├─4026532508 user 1 29376 yamato /usr/lib64/firefox/

4026533733 user 1 30839 yamato /opt/google/chrome-
4026533734 user 15 10076 yamato /opt/google/chrome-
user namespaces 4026533733 and 4026533734 are orphans.
lsns could not find their parents.
With this change:
# ./lsns-with-changes -Tparent
NS TYPE NPROCS PID USER COMMAND
4026531837 user 404 1 root /usr/lib/systemd/
├─4026532508 user 1 29376 yamato /usr/lib64/firefo

│ └─4026533734 user 14 10076 yamato /opt/google/chrom
Now user namespaces 4026533733 and 4026533734 are integrated to the
tree. lsns interpolates the missing namespace 4026532639 and
4026532637 for the integration.
The original output for -Towner:
# ./lsns -Towner
NS TYPE NPROCS PID USER COMMAND
4026531837 user 405 1 root /usr/lib/systemd/s
├─4026531835 cgroup 431 1 root /usr/lib/systemd/s

4026532638 pid 1 30839 yamato /opt/google/chrome
4026532640 pid 2 30837 yamato /opt/google/chrome
...
pid namespaces 4026532638 and 4026532640 are orphans.
lsns could not find their owners.
With this change:
# ./lsns-with-changes -Towner
NS TYPE NPROCS PID USER COMMAND
4026531837 user 403 1 root /usr/lib/systemd

Now pid namespaces 4026532638 and 4026532640 are integrated to the
tree. lsns interpolates the missing namespace 4026532639 and
4026532637 for the integration.

This is a preparation change for planed "tree interpolation" patch.
parentid, ownerid, parentns, and ownerns were members of
lsns_namespace struct. When interpolating missing namespaces
for building a unified name space tree, duplicated functions
are needed; one is for parentid and parentns members, and
another is for ownerid and ownerns members. To avoid the
duplication, this change unifies the members as following:
parentid and ownerid => related_id [2]
parentns and ownerns => related_ns [2]

Suggested by Karel Zak.
`--tree` option is introduced as replacement for `--nstree`.
In addition to `parent` and `owner`, `--tree` take `process` as the
option argument.

Introduce new option -T[parent|owner]|--nstree[=parent|=owner].
With this change, lsns prints parent/child relationship tree if
"-T parent" is given and owner/owned relationship tree if "-T owner is given.
Passing only "-T" is same as passing "-Towner."

I'm working on building initramfs images directly from normal
packages, which means that the pristine system rpms should behave
correctly as much as possible also in the initrd. There usually isn't
enough time for the timer to actually fire, but starting it gives a
line on the console and generally looks confusing and sloppy. So let's
skip the timer if it ever ends up being enabled in the initrd.
Checking for /etc/initrd-release is the standard condition that
systemd's initrd units use.
The command-line option --force is defined as "disable all checks",
but the current code does not follow this idea. We need a way how to
disable read from the device (for example for dm-integrity devices).

The mount() command associated with this error message is not about
unmounting the proc fs, but rather about changing the propagation
of mount events for the proc fs. Rewrite the error message to
reflect this.
* `RFKILL_EVENT_SIZE_V1` is defined as sizeof(struct rfkill_event), so let's use %zu
* cast `len` to size_t to make it usable with %zu
