Doesn't this clash with the same Kconfig symbol in arch/x86/Kconfig?
traditionally, perf has not required a kernel config to build it. The
above grabs some symbols for a standalone perf config. I guess that's a
question to be answered - should the kernel's config files should be
used for perf (or a tools target in general).
Also, perf can be built outside of the kernel tree. Tying the build to
the kernel config files would have an affect on that option.
Something to look at for the next version.
