[PATCH 0/2] KVM: arm64: Tentative fixes for page-table lifetime issues

[Will Deacon <will@kernel.org>]

Hi all,

Sashiko highlighted a couple of potential page-table lifetime issues
in the upstream code while it was reviewing the pKVM protected memory
series. They make sense to me so I've had a crack at fixing them and
writing a better description of the problem in the commit message.

For the second issue, I've tested it by forcing the notifier
registration to fail and then watching the SecPageTables line in
/proc/meminfo after attempting to create VMs.

Cheers,

Will
