Merge branch 'dt/schema-cleanups' into dt/linus

Merge branch 'x86/entry' into ras/core

to fixup conflicts in arch/x86/kernel/cpu/mce/core.c so MCE specific follow
up patches can be applied without creating a horrible merge conflict
afterwards.

tools, bpftool: Minor fixes for documentation

Bring minor improvements to bpftool documentation. Fix or harmonise
formatting, update map types (including in interactive help), improve
description for "map create", fix a build warning due to a missing line
after the double-colon for the "bpftool prog profile" example,
complete/harmonise/sort the list of related bpftool man pages in
footers.

v2:
- Remove (instead of changing) mark-up on "value" in bpftool-map.rst,
when it does not refer to something passed on the command line.
- Fix an additional typo ("hexadeximal") in the same file.

Merge branch 'bpf_link-observability'

Andrii Nakryiko says:

====================
This patch series adds various observability APIs to bpf_link:
- each bpf_link now gets ID, similar to bpf_map and bpf_prog, by which
user-space can iterate over all existing bpf_links and create limited FD
from ID;
- allows to get extra object information with bpf_link general and
type-specific information;
- implements `bpf link show` command which lists all active bpf_links in the
system;
- implements `bpf link pin` allowing to pin bpf_link by ID or from other
pinned path.

v2->v3:
- improve spin locking around bpf_link ID (Alexei);
- simplify bpf_link_info handling and fix compilation error on sh arch;
v1->v2:
- simplified `bpftool link show` implementation (Quentin);
- fixed formatting of bpftool-link.rst (Quentin);
- fixed attach type printing logic (Quentin);
rfc->v1:
- dropped read-only bpf_links (Alexei);
- fixed bug in bpf_link_cleanup() not removing ID;
- fixed bpftool link pinning search logic;
- added bash-completion and man page.
