Changes since 20210915:

The bpf-next tree still had its build failure so I used the version from
next-20210913.  

Arnaldo,

could you please push Andrii's fix into your tree asap
and then cleanup/follow up with a better fix if  necessary?  

It's there since yesterday:

https://git.kernel.org/pub/scm/linux/kernel/git/acme/linux.git/commit/?h=perf/core&id=00e0ca3721cf2ddcb38cf676a3de61933640d31d

Replying just now since it's a holiday here and I was AFK.

But that is not in any tree that is included in linux-next (and when it
does appear, it will be in the tip tree which gets merged well after
the bpf-next tree).  I will include that patch as a merge fix up for
the bpf-next tree until that patch has gone into Linus' tree ... so,
someone has to ensure that this patch get into Linus tree *before* the
bpf-next tree.

So, do you see the problem?  Linus' tree is fine on its own.  The
bpf-next tree has a patch that breaks Linus' tree, but the breakage is
not seen in the bpf-next tree because it is base on v5.14 and the
interacting patch is in v5.15-rc1.
