smp: Add a smp_cond_func_t argument to smp_call_function_many()
on_each_cpu_cond_mask() allocates a new CPU mask. The newly allocated
mask is a subset of the provided mask based on the conditional function.
This memory allocation can be avoided by extending smp_call_function_many()
with the conditional function and performing the remote function call based
on the mask and the conditional function.
Rename smp_call_function_many() to smp_call_function_many_cond() and add
the smp_cond_func_t argument. If smp_cond_func_t is provided then it is
used before invoking the function. Provide smp_call_function_many() with
cond_func set to NULL. Let on_each_cpu_cond_mask() use
smp_call_function_many_cond().
