cpumask: convert kernel/profile.c
Impact: Reduce kernel memory usage, use new cpumask API.
Avoid a static cpumask_t for prof_cpu_mask, and an on-stack cpumask_t
in prof_cpu_mask_write_proc. Both become cpumask_var_t.
prof_cpu_mask is only allocated when profiling is on, but the NULL
checks are optimized out by gcc for the !CPUMASK_OFFSTACK case.
Also removed some strange and unnecessary casts.
