Hi Vineet,
Just noticed that in comments for smp_call_function_many() it is said that
preemption must be disabled during its execution. And that function gets executed
among other ways like that:
-------------------------->8-----------------------
flush_tlb_range()
-> on_each_cpu_mask()
-> smp_call_function_many()
-------------------------->8-----------------------
In general I prefer not to - Peter what say you ?
I'm not seeing right now any real problem with current implementation but
some architectures do that thus the question.
