Re: [PATCH v2 6/6] x86/percpu: Share decrypted storage before guest CPU setup

[sashiko-bot@kernel.org]

> Convert every possible CPU's decrypted section after per-CPU setup and
> before the boot CPU registers its buffers. This replaces KVM's object
> loop and shares VMware steal-time storage without a driver conversion
> path or readiness state.
> 
> UP KVM registers inside setup_arch(), so convert before guest_late_init()
> there and move VMware's UP registration to that hook. Stop boot on a
> conversion failure: inconsistent page state must not be published to the
> hypervisor. Host SME keeps its existing mappings. Skip Hyper-V vTOM
> per-CPU storage: its visibility callbacks require later Hyper-V
> initialization.
