The cpu_any*() APIs comment states that it returns a "random" cpu within
the given cpumask. Hoever it's not actually random as random itself
stands a meaning for uniform distribution.

cpu_any*() APIs are a naming convention for the caller to states that it
doesn't care which CPU it gets, so change "random" to "arbitrary" would
be more appropriate.

Hi I Hsin,

Can you please fix this typo, drop quotes around the 'arbitrary' word,
as suggested by Mark, and send v2?

Please also keep Mark in the loop.

Thanks,
Yury
