Punit Agrawal 4ea5af5311 KVM: arm64: Support dirty page tracking for PUD hugepages ... In preparation for creating PUD hugepages at stage 2, add support for write protecting PUD hugepages when they are encountered. Write protecting guest tables is used to track dirty pages when migrating VMs. Also, provide trivial implementations of required kvm_s2pud_* helpers to allow sharing of code with arm32.
