This 'DEBUG'-prefixed version of PERF_USE_VMALLOC is not used anywhere.
It appears to be leftovers from commit 906010b "perf_event: Provide
vmalloc() based mmap() backing" that introduced it.
Not sure what commit cb30711 "perf_event: Don't allow vmalloc() backed
perf on powerpc" was trying to do with it either.
