Frederic,
I noticed that an allnoconfig x86 build builds perf events.
I think it comes from this commit of yours:

hw-breakpoints: Fix hardware breakpoints -> perf events dependency
The kbuild's select command doesn't propagate through the config
dependencies.
Hence the current rules of hardware breakpoint's config can't
ensure perf can never be disabled under us.
Given that perf is quite big these days, and there are likely a lot of systems
which don't need it (everything which noone does development with)
that seems very drastic.
Is there a way to solve your old build problem without that
unconditional select?
