Heiko Carstens 36c2733c43 s390/mm,ptdump: hold memory hotplug lock while walking for kernel page table dump 
This is the s390 variant of commit bf2b59f60e ("arm64/mm: Hold
memory hotplug lock while walking for kernel page table dump").

Right now this doesn't fix any real bug, however as soon as kvm
patches get merged which make use of memory remove we might end up
dereferencing/accessing freed page tables.

Therefore fix this potential bug already now.
