[PATCH v2 0/3] KVM: arm64: Tidy up is_created

[Fuad Tabba]

Hi folks,

Changes since v1 [1]:
- Carried Keir's Reviewed-by. No code changes.

This small series tidies up the host-side kvm->arch.pkvm.is_created flag,
which tracks whether the hypervisor-side (EL2) VM has been instantiated.

It comes out of the ongoing pKVM (protected KVM) upstreaming work and runs
in parallel with it. The changes only remove dead or redundant code around
the flag, not any of the functional paths that work touches, so there is no
dependency in either direction and the two can be applied in any order.

is_created stays: the pKVM handle is reserved early (so host MMU-notifier
TLB invalidations have a valid handle before the first vCPU run), so a
non-zero handle no longer implies the EL2 VM exists. is_created is what
distinguishes "reserved" from "created", and the teardown path relies on it.
Only the cruft around it goes.

Cheers,
/fuad
