[PATCH 02/17] drivers: rename num_*_cpus variables

Yury Norov
2021-12-18T21:20:40Z

Some drivers declare num_active_cpus and num_present_cpus,
despite that kernel has macros with corresponding names in
linux/cpumask.h, and the drivers include cpumask.h

The following patches switch num_*_cpus() to real functions,
which causes build failures for the drivers.
