[PATCH 12/28] perf tools: Replace STR() calls with __stringify()

From: Arnaldo Carvalho de Melo
Date: Wed Apr 19 2017 - 12:25:18 EST


From: Arnaldo Carvalho de Melo <acme@xxxxxxxxxx>

Both do the same thing, the later is the one we get from
linux/stringify.h, i.e. we now use the same function name/practice as
the kernel sources.
