Merge v5.6-rc2 into drm-misc-next

Lyude needs some patches in 5.6-rc2 and we didn't bring drm-misc-next
forward yet, so it looks like a good occasion.

Merge branch 'runqslower'

Andrii Nakryiko says:

====================
Based on recent BPF CO-RE, tp_btf, and BPF skeleton changes, re-implement
BCC-based runqslower tool as a portable pre-compiled BPF CO-RE-based tool.
Make sure it's built as part of selftests to ensure it doesn't bit rot.

As part of this patch set, augment `format c` output of `bpftool btf dump`
sub-command with applying `preserve_access_index` attribute to all structs and
unions. This makes all such structs and unions automatically relocatable under
BPF CO-RE, which improves user experience of writing TRACING programs with
direct kernel memory read access.

Also, further clean up selftest/bpf Makefile output and make it conforming to
libbpf and bpftool succinct output format.

v1->v2:
- build in-tree bpftool for runqslower (Yonghong);
- drop `format core` and augment `format c` instead (Alexei);
- move runqslower under tools/bpf (Daniel).

tools/bpf: Add runqslower tool to tools/bpf

Convert one of BCC tools (runqslower [0]) to BPF CO-RE + libbpf. It matches
its BCC-based counterpart 1-to-1, supporting all the same parameters and
functionality.

runqslower tool utilizes BPF skeleton, auto-generated from BPF object file,
as well as memory-mapped interface to global (read-only, in this case) data.
Its Makefile also ensures auto-generation of "relocatable" vmlinux.h, which is
necessary for BTF-typed raw tracepoints with direct memory access.
