[PATCH v11 6/6] KVM: arm64: Document MTE capability and ioctl

A new capability (KVM_CAP_ARM_MTE) identifies that the kernel supports granting a guest access to the tags, and provides a mechanism for the VMM to enable it. A new ioctl (KVM_ARM_MTE_COPY_TAGS) provides a simple way for a VMM to access the tags of a guest without having to maintain a PROT_MTE map

[PATCH v11 5/6] KVM: arm64: ioctl to fetch/store tags in a guest

The VMM may not wish to have it's own mapping of guest memory mapped with PROT_MTE because this causes problems if the VMM has tag checking enabled (the guest controls the tags in physical RAM and it's unlikely the tags are correct for the VMM). Instead add a new ioctl which allows the VMM to easi

Add a new VM feature 'KVM_ARM_CAP_MTE' which enables memory tagging for a VM.

[PATCH v11 1/6] arm64: mte: Sync tags for pages where PTE is untagged

A KVM guest could store tags in a page even if the VMM hasn't mapped the page with PROT_MTE. So when restoring pages from swap we will need to check to see if there are any saved tags even if !pte_tagged(). However don't check pages which are !pte_valid_user() as these will not have been swapped o
