Bug description:
The following upstream fix is requested to resolve issues with SEV
live-migration:
https://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git/commit/?id=ac3f9c9f1b37edaa7d1a9b908bc79d843955a1a2
More details in:
https://canonical.lightning.force.com/lightning/r/Case/5008e00000HNdQ8AAL/view
Testing:
- Boot-tested each of f/gcp, j/gcp and l/gcp
- GCP has tested each of them as well and reported that the live-migration
issue under SEV gets resolved.
Regression potential:
- The change affects arch/x86/kernel/kvm.c so KVM on x86 can be impacted. It
is a minimalistic change though, and regression risk is considered low.
