2014-12-17tools: Adopt rounddown_pow_of_two and depsArnaldo Carvalho de Melo
Will be used to make sure we pass a power of two when automatically setting up the perf_mmap addr range length, as the kernel code validating input on /proc/sys/kernel/perf_event_mlock_kb accepts any integer, if we plain use it to set up the mmap lenght, we may get an EINVAL when passing a non power of two.
