[PATCH 0/3] mm, memory_hotplug: fix few soft lockups in memory hotadd

Johannes has noticed few soft lockups when adding a large nvdimm
device. All of them were caused by a long loop without any explicit
cond_resched which is a problem for !PREEMPT kernels. The fix is quite
straightforward. Just make sure that cond_resched gets called from time
to time.

Could you consider these for merging?
