[PATCH kernel 0/2] powerpc/iommu: Stop crashing the host when VM is terminated

[Alexey Kardashevskiy]

Killing a VM on a host under memory pressure kills a host which is
annoying. 1/2 reduces the chances, 2/2 eliminates panic() on
ioda2.


This is based on sha1
f40ddce88593 Linus Torvalds "Linux 5.11".

Please comment. Thanks.
