| H A D | tdp_mmu.h | 46044f72 Wed Oct 14 13:26:57 CDT 2020 Ben Gardon <bgardon@google.com> kvm: x86/mmu: Support write protection for nesting in tdp MMU
To support nested virtualization, KVM will sometimes need to write
protect pages which are part of a shadowed paging structure or are not
writable in the shadowed paging structure. Add a function to write
protect GFN mappings for this purpose.
Tested by running kvm-unit-tests and KVM selftests on an Intel Haswell
machine. This series introduced no new failures.
