[PATCH 0/3] smp: Avoid memory allocation in on_each_cpu_cond()

[Sebastian Andrzej Siewior]

x86 is using on_each_cpu_cond_mask() in native_flush_tlb_others() in a
preempt disabled section. The memory allocation in
on_each_cpu_cond_mask() gives me a headache on RT.
This is an attempt to get rid of the memory allocation and potentially
accelerating the code path :)
