    perf cpumap: Introduce cpu_map__snprint_mask() · 4400ac8a
    Namhyung Kim authored
    The cpu_map__snprint_mask() generates a string representation of a
    cpumask bitmap.  For cpu 0 to 11, it'll return "fff".
    
    Committer notes:
    
    Fix compiler warning on some toolchains:
    
        19 fedora:24-x-ARC-uClibc: FAIL
    
        CC       /tmp/build/perf/util/cpumap.o
      util/cpumap.c: In function 'hex_char':
      util/cpumap.c:679:2: error: comparison is always true due to limited range of data type [-Werror=type-limits]
        if (0 <= val && val <= 9)
        ^
      cc1: all warnings being treated as errors
    
    Applying patch from Namhyung that makes function receive an 'unsigned
    char', that is what the callers are passing to this function.
