[PATCH v1 0/3] Bring back vmlinux.h generation

[PATCH v1 0/3] Bring back vmlinux.h generation

[Ian Rogers]

Commit 760ebc45746b ("perf lock contention: Add empty 'struct rq' to
satisfy libbpf 'runqueue' type verification") inadvertently created a
declaration of 'struct rq' that conflicted with a generated
vmlinux.h's:

```
util/bpf_skel/lock_contention.bpf.c:419:8: error: redefinition of 'rq'
struct rq {};
       ^
/tmp/perf/util/bpf_skel/.tmp/../vmlinux.h:45630:8: note: previous definition is here
struct rq {
       ^
1 error generated.
```

Fix the issue by moving the declaration to vmlinux.h. So this can't
happen again, bring back build support for generating vmlinux.h then
add build tests.

[PATCH v1 1/3] perf build: Add ability to build with a generated vmlinux.h

[Ian Rogers]

Commit a887466562b4 ("perf bpf skels: Stop using vmlinux.h generated
from BTF, use subset of used structs + CO-RE") made it so that
vmlinux.h was uncondtionally included from
tools/perf/util/vmlinux.h. This change reverts part of that change (so
that vmlinux.h is once again generated) and makes it so that the
vmlinux.h used at build time is selected from the VMLINUX_H
variable. By default the VMLINUX_H variable is set to the vmlinux.h
added in change a887466562b4, but if GEN_VMLINUX_H=1 is passed on the
build command line then the previous generation behavior kicks in.

The build with GEN_VMLINUX_H=1 currently fails with:
```
util/bpf_skel/lock_contention.bpf.c:419:8: error: redefinition of 'rq'
struct rq {};
       ^
/tmp/perf/util/bpf_skel/.tmp/../vmlinux.h:45630:8: note: previous definition is here
struct rq {
       ^
1 error generated.
```

[PATCH v1 2/3] perf bpf: Move the declaration of struct rq

[Ian Rogers]

struct rq is defined in vmlinux.h when the vmlinux.h is generated,
this causes a redefinition failure if it is declared in
lock_contention.bpf.c. Move the definition to vmlinux.h for
consistency with the generated version.
